OPERATION
NOTE: The following guide to operating the
ProLaser III lidar system is not intended to be a
training program. Before operating this unit or any
other speed measuring system, Kustom Signals urges
all operators to have prior training in lidar speed
monitoring devices. Such courses are offered by
Kustom Signals, various state and local agencies and
either IPTM (Institute of Police Technologies and
Management) or Northwestern University. Contact
your District Manager or Kustom Signals at 1-800-
4KUSTOM for further details.
SETUP
There are several factors to be taken into account
when setting up to make speed or distance measurements
with the ProLaser III. They have to do with the location of
the instrument relative to the roadway upon which traffic
is moving, and with the actual setup in or around the
patrol car.
In selecting a location for monitoring traffic, be aware
that the ProLaser III is subject to the
cosine effect
in the
same manner as conventional microwave radar and other
laser-based speed measuring systems. The cosine effect is
a principle which states that the apparent measured
speed of a target will be decreased from its actual speed,
depending upon the angle between the direction of
observation and the true direction of travel.
