Section #7 - Glossary
beam divergence: The tendency of a laser beam to expand in
diameter as it moves away from the source,
measured in milliradians (mrad).
Continuous Mode: Alternate speed measurement mode. Allows you
to take several successive readings of a target
vehicle. Re-trigger for each new target. See page 22.
Delta Distance Test: Uses two measurements each to a known
distance to verify the measurement accuracy of
the TruSpeed. See page 28.
Display Integrity Test: Allows you to verify that all segments of the LCD
screen are operating. See page 24.
Fixed Distance Test: Uses one measurement to a known distance to
verify the measurement accuracy of the
TruSpeed. See page 27.
laser:
Light Amplification by Stimulated Emission of
Radiation.
lidar: A device that is similar in operation to radar, but
emits pulsed laser light instead of radio waves.
microcontroller: The computer processor that controls all of the
functions of the TruSpeed.
Receive Lens: Located on the front panel of the TruSpeed, it is
the bottom lens and receives the signals back
from the target and then feeds the signal
information to the microcontroller.
reticle: A scale located in the sighting scope that helps
you aim to your target. It is visible when the
TruSpeed is powered ON. You may need to press
the TRIGGER to see the reticle. See page 5.
Transmit Lens: Located on the front panel of the TruSpeed, it is
the top lens and transmits the infrared laser
signals.
Weather Mode: Alternate speed measurement mode. The laser
only acquires targets that are beyond the range
where weather affects the laser’s ability to
capture a speed reading. Targets must be at a
distance greater than 200 feet. See page 21.
