LASER scanners and LiDARs for underwater operations:
A resource guide (Page 1 of 3)
LASER stands for ‘Light Amplification by Stimulated Emission of
Radiation’. It is a highly coherent, monochromatic (single-wavelength),
and directional beam of light emitted by a specific device through a
quantum-mechanical process. Unlike ordinary light, which spreads in
all directions and contains many wavelengths, LASER light has the
following properties:
•
Coherent - All waves are in phase with each other.
•
Monochromatic - It consists of a single, precise wavelength (color).
•
Collimated - It travels in a tight, parallel beam with minimal
divergence.
•
Intense - A lot of energy must be concentrated in a small area to
produce a beam of light with these characteristics.
The creation of a LASER can be understood through the following key
concepts and steps:
1.
Energy levels and photon emission:
Electrons in atoms occupy specific, discrete energy levels. When
an electron absorbs energy, it can move from a lower-energy
level, commonly called the ‘ground state’, to a higher-energy level,
also called the ‘excited state’.
This excited state is temporary because it is unstable. Therefore,
when the electron returns to a lower energy level or the ground
state, it releases the absorbed energy as light (a photon). This
light has specific wavelengths, unique to each element, producing
an emission spectrum.
2.
Stimulated emission and LASER light:
According to Einstein’s theory, an excited atom struck by a photon
of the right energy can be stimulated to emit a second photon,
which is identical in wavelength, direction, and phase to the first
one. This process creates a cascade of identical photons,
producing coherent light.
Enough energy should be “pumped” into the medium to create the
process above, so that more atoms are in the ‘excited state’ than
the ‘ground state’, which is called “population inversion”. This is
achieved using electricity, another light source, or chemical
reactions.
3.
LASER resonator setup:
The gain medium is placed between two mirrors: one fully
reflective and one partially transparent. Photons bounce back and
forth, stimulating more emissions, building an avalanche of
coherent light.
The partially transparent mirror allows a fraction of the amplified
light to escape as the LASER beam.
Introduction to LASER: Meaning and Creation Process
LASER Classification by Wavelengths (colors)
LASERs are commonly categorized by their emission wavelength, which
may be visible or invisible, and are expressed in nanometres.
•
Visible LASERs include the following spectrum of colors that range
from 380 to 700 nm (380 nm and 700 nm being the boundaries
between non-visible and visible lights):
- Violet is emitted by wavelengths from 380 to 450 nm. LASERS
emitting such wavelengths are used for high-density optical data
storage (e.g., Blu-ray players), fluorescence microscopy, biological
imaging, and counterfeit detection.
- Blue emits wavelengths from 450 to 495 nm. These wavelengths
are used for laser pointers and displays, medical applications such
as phototherapy, data storage, high-resolution printing, underwater
imaging and scanning (particularly where water clarity is high),
and high-resolution metrology.
- Green is emitted at wavelengths from 495 to 570 nm. It is
commonly used for laser pointers because of its high visibility to
the human eye, laser light shows and entertainment, alignment
and surveying tools, bathymetry (aerial and underwater),
measurements (in air and underwater), as well as medical
treatments such as photocoagulation in ophthalmology.
- Yellow is emitted at wavelengths between 570 and 590 nm. These
LASER lights are often used for dermatological treatments and
various scientific research.
- Orange light is emitted at wavelengths from 590 to 620 nm and is
used for a few medical applications. It must be noted that it is a
relatively less commonly used range compared to others.
- Red is emitted at wavelengths from 620 to 700 nm. These
wavelengths are commonly found in laser pointers and barcode
scanners, optical communication, printers, CD/DVD players,
photodynamic therapy, and other medical applications.
•
Non-perceived colors include:
- Ultraviolet (UV), whose wavelengths are < 380 nm, is commonly
used for sterilization and semiconductor lithography
- Infrared (IR), with wavelengths > 700 nm, is commonly used for
detection, telecommanding, and other telecom applications.
•
To summarise, on the topic of this presentation, LASER colors used
for bathymetric and underwater applications are blue and green:
- Blue lasers are sometimes preferred for specific underwater
imaging or scanning tasks, particularly where water clarity is high.
- Green lasers are a common choice for underwater operations
because they balance well with water penetration and detector
sensitivity.
LASER scanners and LiDARs
“LASER scanners” and “LiDAR (Light Detection and Ranging)” are LASER-
based measuring and monitoring tools whose terminology is often
confused in marketing and job presentations, leading to
misunderstandings about their precise definitions and applications. This
confusion typically arises because both tools employ the same basic
principle described above. However, the way this principle is applied
differs based on the specific purpose for which each tool is designed.
To resolve this confusion it is necessary to consider the principles used
to calculate distances and reconstruct 3D point clouds.
•
Time-of-Flight (TOF) Measurement Systems:
These systems measures the time it takes for the laser pulse to
travel to a surface and back: A laser pulse is emitted, and the
scanner measures the time it takes for the pulse to return after
reflecting off the surface targeted. The distance is then calculated
using the speed of light and the formula “(speed of light x round trip
travel time) / 2 “. This is done through a LASER source that emits
millions of pulses per second that are bounced off a mirror rotating
at high speeds which covers the full field of view. When a pulse hits
an object, the light scatters, and a portion of it reflects back toward
the scanner’s sensor. Usually, the scanner head rotates 360°
horizontally while the mirror rotates vertically, creating a spherical
capture of the surroundings.
Systems using this principle of distance calcuation are to be
classified “ LiDARs”
We can refer 3 categories of LiDARS:
- Terrestrial LiDARs are used in air only. They exploit wavelenghts
from 785 nm to 1550 nm, and are used in construction, urbanism,
monument monitoring, archeology, mapping and similar activities.
They can be installed at ground level, or on aerial vehicles,
depending on the work to be performed.
- Bathymetric LiDARs are typically mounted on aerial platforms
(aircraft or drones). Unlike terrestrial LiDARs, they use a
dual wavelength system integrated into the same instrument:
1) The infrared/near-Infrared (NIR) channel (approximately 1064
nm) measures the water surface, similar to terrestrial LiDAR.
2) The green channel (approximately 532 nm, within 495–570
nm) penetrates the water column to measure the bottom of
rivers, lakes, or coastal seas.
The system calculates the depth by subtracting the distance to the
water surface (measured by the infrared channel) from the
distance to the bottom (measured by the green channel). This
system is effective in clear water to a depth of about 50 meters.
However, its performance decreases in turbid water due to
scattering and absorption.
- Underwater LiDARs use the same principles than terrestrial
LiDARs excepth they use green and blue wavelenghts (450 to 570
nm). it must be noted that operational scanning distances vary
from 1-3 m in turpid waters to up to 30 m in very clear waters
It is worth noting that the refraction of water must be taken into
account with Bathymetric and underwater LIDARs. This is done
using Snell’s law, which describes how light bends when it passes
from one medium to another for Bathymetric LIDARs, and adjust
TOF calculations for slower light speed and window refraction
(refractive index of water =1.33, instead of 1.0003 in air) for
underwater LiDARs.
•
LASER Scanners Utilizing Triangulation Calculations:
This distance calculation principle, mainly used for underwater
LASER scanners, involves a laser that emits spots or lines onto a
target, and a camera or position-sensitive detector that views the
spot from a known offset angle. Unlike time-of-flight (TOF) systems,
the emitter and detector in this setup are not collinear, with typical
baselines ranging from a few centimeters to several tens of
centimeters, depending on the equipment.
By utilizing the known baseline between the emitter and the detector,
the angle between the emitted and received lines can be measured
to form a triangle. This enables the distance to the laser light to be
calculated using the triangulation formula.
It is important to note that since the system is designed for
underwater use, the triangulation geometry is pre-calibrated for the
refractive index of water. This calibration allows the camera or
detector to account for the displacement of the spot caused by
refraction.
Operational distances to the target are typically less than 5m in clear
water. However, these systems generally achieve an accuracy of
better than 1 mm, unlike TOF-based systems.
In addition to the definitions and operating principles mentioned above,
it is essential to consider the history of LASER discovery and the
development of the tools this article discusses (LiDAR and underwater
LASER scanners) to better understand their use, chronology, and
possible near-future evolution.
It is worth noting that, for convenience, only the main steps and
scientists involved in the development of such research are mentioned.
•
Initial theories and research:
Max Planck (1858-1947) proposed that energy is emitted in discrete
packets called quanta, laying the groundwork for quantum
mechanics in his paper "On the Law of the Energy Distribution in the
Normal Spectrum," first published in German in 1901.
Albert Einstein then theorized the principle of LASER in his 1916-
1917 paper "On the quantum theory of radiation", built on Max
Planck's work. The phenomena described by Albert Einstein were
confirmed by Rudolf Ladenburg (1882-1952) in 1928.
Postwar fundamental research was undertaken in the USA, UK,
France, Germany, and the Soviet Union to advance Albert Einstein's
theory. Among the numerous research undertaken, we can note the
laboratory demonstration of the theory of Albert Einstein by Willis E.
Lamb (1902-1988) & Robert C. Retherford (1921-?) in 1947, and the
method for optical pumping (see the explanation of LASER) proposed
in 1950 by Alfred Kastler (1902-1984).
•
Chronological development of LASER technology:
Theodore Maiman (1927-2007), an American physicist at Hughes
Research Laboratories, built and operated the first working laser in
1960. Other researchers, including those at the French Centre
National d'Études des Télécommunications (CNET), contributed to the
development of the first semiconductor laser in 1962. Additionally,
German teams at the Technical University of Berlin also built early
lasers. Similar research has been conducted in various countries,
including the Soviet Union (now the Russian Federation), since the
1960s.
LiDAR (Light Detection and Ranging) technology emerged following
Maiman’s 1960 demonstration and rapidly evolved, with early
prototypes emerging soon after. Throughout the 1960s and 1970s,
key innovations included mechanisms to steer laser beams across a
field of view, the use of highly sensitive detectors such as avalanche
photodiodes (APDs) and photomultiplier tubes (PMTs), and methods to
generate extremely short, high-intensity laser pulses. Furthermore,
advances in electronics and miniaturization during the 1990s led to
the development of a variety of portable terrestrial scanners.
The first LiDAR systems for underwater imaging were developed by
the US Navy to address the limitations of the existing SONARs (Sound
Navigation and Ranging) for tasks that require precise imaging.
Among these developments, note Fraunhofer IPM's (Germany) early
pulsed time-of-flight systems for subsea use. The company "3D at
Depth" (USA) demonstrated the first subsea scanning LiDAR in 2009,
with ROV-integrated prototypes by 2012.
Development continued with the development of commercial
underwater LASER scanner systems (see the description above), in
addition to those made on underwater and bathymetric LiDARs. As
an example, recent projects include research by the Swiss Center
for Electronics and Microtechnology (CSEM) and the Institut Français
de Recherche pour l'Exploitation de la Mer (French Research Institute
for Exploitation of the Sea), commonly called IFREMER, for seafloor
mapping (2025) and green-wavelength systems penetrating 10-
20m in turbid water.
While LiDAR had been used for scientific and military applications for
decades, its most transformative commercial application emerged
from underwater vehicles used for mapping and inspections, both
offshore and onshore, and in sensitive facilities such as nuclear
plants.
•
Advantages and future progress
Underwater LiDAR and LASER scanners enable more effective
operational planning, depending on the project, and allow continuous
monitoring and imaging of ongoing operations. Their 3D, high-
resolution images provide greater detail of inspected elements and
can quickly and faithfully represent targeted objects. Also, the
development of low-cost aerial vehicles enables rapid bathymetric of
shallow mapping areas at reasonable cost, producing results similar
to those obtained underwater with small or medium autonomous
vehicles and divers.
The evolution of these tools is therefore tied to improvements in
sensor quality and performance, as well as to better hardware
integration, often driven by miniaturization.
Future improvements may also stem from software advances that
enable fusion of data from these tools with information from other
systems, such as SONARs and photogrammetry described earlier in
this section, improving accuracy under variable conditions. That
could result from their systematic integration into underwater
vehicles alongside other systems. This fused data may also be
transmitted to divers’ helmets via systems such as the Diver
Augmented Vision Display (DAVD), allowing a diver to directly view
images captured during his dive, increasing awareness of the details
of the piece being worked on.
History, advantages of these tools, and future evolution
The Newton Labs M3200UW and
M310UW are laser scanners

Training
LASER technologies are highly specialized and relatively new in our
industry, resulting in a limited number of establishments capable of
offering relevant training. For this reason, manufacturers usually
provide training on their premises but also on those of their customers.
E-learning modules are also often proposed, notably regarding the
control of various applications.
In addition to the above, reputable organizations and universities also
offer academic programs. Regarding the training provided by these
institutions, it is worth noting that while manufacturer courses focus on
the devices they design, academic training is often open to a variety of
equipment, depending on the course's focus. For companies seeking
personnel skilled in specific tools, this may lead to more general
training, resulting in the inconvenience that the student may not be fully
acquainted with the company's equipment. Also note that universities
usually offer training programs as part of long-term curricula that
include other modules. Therefore, LASER-derived tools are rarely
taught in isolation at these institutions, and the courses they offer are
often more theoretical and aligned with other modules that should
result in the formation of high-level technicians and engineers.
As the previous section lists manufacturers, this section focuses only
on academic or similar formations. They are classified by the areas in
which they are located, with each presentation indicating whether the
