Canadian DragonEye Speed LIDAR

Operator Manual

The LIDAR's laser beam is invisible, but will be contained within the

aiming reticle. This is your aim point for target vehicles.

Roadside Setup

When first learning to use the DragonEye Speed LIDAR®, it is best to

select a straight stretch of roadway with a line of sight of 150 metres

or more. (or follow your provincial program)

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 Appendix A of this manual. (Note: The cosine effect applies to

both stationary 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 vehicles lane of travel. For example, if the operator is 9 metres

from the vehicle's lane of travel, the vehicle should be targeted at 90

metres or greater. This would result in a measured speed reading

which was approximately 0.5% less than actual.

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.

You may hear an intermittent audible tone as the LIDAR searches for

a valid target signal. You will also see "----"displayed in the HUD

indicating the laser is firing and a reading is being acquired. Once

target vehicle data is identified, the LIDAR will produce a continuous
