• Make sure the LIDAR's brightness setting is on medium
or high if working in daylight .) .
The LIDAR's laser beam is invisible, but will be contained within the
aiming reticle . This is your aim point for target vehicles .
5.5 Roadside Setup
When first learning to use the DragonEye Compact LIDAR, it is best to
select a straight stretch of roadway with a line of sight of 500 ft
(150 m) or more .
Approaching or receding vehicles should be targeted such that your
line of sight through the HUD is as parallel as possible to the path of
the target vehicle . This will minimize the "cosine effect" as described
in Chapter 10 of this manual .
• The cosine effect applies to both RADAR and LIDAR
systems and always results in a slightly lower than
actual reading . .
A good rule of thumb for approximately straight roadways is to
target a vehicle at a range which is at least ten times the operator's
perpendicular distance to the vehicle's lane of travel . For example,
if the operator is 30 feet (9 m) from the vehicle's lane of travel, the
vehicle should be targeted at 300 feet (90 m), or greater . This would
result in a measured speed reading which was approximately 0 .5%
less than actual .
5.6 Measuring Vehicle Speeds
For approaching targets, aim the LIDAR's reticle at the front grill or
front license plate of the vehicle . Good targets for receding vehicles
are the license plate or tail lights . Use the boundaries of the reticle
pattern to ensure only the intended vehicle is being targeted .
Squeeze and hold the laser fire trigger while maintaining your aim .
