L1000 LASER PROFILER
Subsea Profiler for 3D Data Capture
Overview
Laser Profiling System for Subsea Vehicles
The L1000 Laser Profiling System includes the Cathx
Ocean M12 A1000 Stills camera and Green Line
Laser. The Green line laser is a 520nm long range
laser which produces a straight line with uniform
intensity over a long range due to its optimal
wavelength for water penetration.
This system can capture UHD Still images and laser
profiles in a rapid sequence providing laser xyz data
with co-registered still images.
3-D Point Cloud
A pre-calibrated laser system can be configured for
high density 3D point cloud data capture using a
downward facing Green line Laser and an M12 A1000
Camera at a suitable angle for optimum
measurement and within the physical limits of the
vehicle.
Range and Scale Measurement
A laser system for range and scale can easily be set
up using the M12 Camera downward facing and a
parallel Green line laser.

Cathx L-1000 System
M12 A1000 Camera
Laser
LED Lighting
12.5MP camera designed as a dual image system capturing laser point cloud
with co-registered still images. The A1000’s high sensitivity combined with
low exposures and progressive scan imaging produces the sharpest image
detail available from moving vehicles.
150mW Class 3B green line laser producing a
straight line with uniform intensity. The laser is
fixed in position at an angle to the camera. The
A1000 camera triggers the laser at up to 40Hz and
captures a laser profile.
Cathx LED lighting systems are triggered by the M12 A1000 camera in
a dual mode laser and white light system. LED lights with a 7000 and
28000 Lumen output are available.
A high powered strobe light with 70,000 lumen output suitable for
long range imaging is in development and due for release in Q2 2015.
