2D and 3D laser scanners. 8frame/sec, 220 degree view, 4600
points/sec. Accuracy +/- 20mm (1 sigma) from 0.5 - 500? 24W power.
System specs can be configured for variety of applications
"LaserMax "
Rochester, NY
tel: 716.272.5420
Manufactures semiconductor laser diode packages and cylindrical
lenses. Packages and small and rugged.
"Odetics "
1515 South Manchester Ave
Anaheim, CA 92802-2907
tel: 714.758.0300
Odetics has made a number of smaller laser scanners. That is, smaller
than their larger ERIM and Perceptron brethren. I have not heard any
independent reviews of the product however.

The Dynasight sensor is a 3-D optical radar that provides real-time
3-D measurements of passive targets with sub-millimeter resolution.
Automatic search and track is provided, eye-safe operation and no
adjustments or alignment required. Original application was head
tracking of computer users but end- effector tracking is also viable.
Operatin range depends on target size 0.1-1.5m for 7mm target, 0.3-4m
for 25mm target and 1 to 6m for 75mm targets. RS-232 interface.
Accuracies 1mm cross range and 4mm down range, resolutions 0.1mm cross
range and 0.4mm down range.
A number of labs have built light stripe devices using projected light
LCD shutters and laser line projectors determine distance through
geometry (as opposed to directly measuring distance through
time-of-flight means) One common need is that of generating the laser
line.

A spin-off of ERIM, Perceptron has also built a number of AM laser
rangefinders. CMU and Caterpillar have used these for map building and
obstacle avoidance work in rough terrain navigation.
LASAR product - provides range and reflectance. Programmable field of
view (15 to 60 deg) Vertical viewing angle from 3 to 72 degrees. Depth
of field from 2 to 40 meters. Up to 1024 x 2048 pixels per image
(programmable) and 360,000 pixels/second data acquisition. VME and
PC-compatible interface cards available. Windows software provides
starting point for custom applications. Less than $50K with a variety
of performance and interface options.

[company HQ is Dr. Johannes Riegl GmbH, 85 km, NW of Vienna, Austria]
Laser range finders, laser speed sensors, laser distance meters, motor
scanners, laser radar systems. Pulsed laser devices. One of the
neatest is the Laser Scout, which gives range, azimuth and inclination
to the target and can be used with GPS to give position coordinates of
the device you are pointing at. $10K. Accuracy up to +/- 10cm
(depending on model)
Laser Radar Scanner (LRS 90-3) is a 1D scanner with 36 deg field of
view and a +/- 3cm accuracy. 2-80m distance, $10K. There are several
other distance models as well.
"Schwarz Electro-Optics "
3404 N. Orange Blossom Trail
Orlando, FL 32804
tel: 407.298.1802
fax: 407.297.1794
Schwarz makes some very nice point range laser ranging devices. These
devices are slightly bigger than a soda can. About $6-12K. CMU
experience for use in simulated unmanned air vehicle platform worked
well. Their MARS (marine angle range system) is a rotating laser
device that reflects off targets in the environment. Max range up to
1000meters using corner prisms. Accuracy +/- 1m. Erebus (Dante)
Scanner used Schwarz device as base.

Z+F are a spinoff from the Technical Univeristy of Munich and have
developed some nice 2 and 3D scanning devices but primarily devlop the
laser electronics. Initially for tunnelling inspection and
verification. Two-frequency phase shift device (10/80MHz) with 15m
depth of field. Resolution to .45mm, accuracy to 5mm, and 500KHz
smapling rate. scanner mechanism provides 360 degree profiles and 2500
pixels/profile and 200 profiles/second. 4.5mW laser (Class 1 >3m). 3D
camera provides 58 deg horz (321 pixels) and 52 deg vert (232 lines)
15-bit range value, 12bit gray level value from reflection signal.
12kg 3D unit.
