Page 18: Roadside Setup
• 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... -
Page 19: Speed Display Lock
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 product a continuous lower frequency tone . When the data from the vehicle reaches an acceptable accuracy level, audible tone will switch to a continuous, higher frequency and the vehicle speed reading will be displayed in the HUD and on the side panel . • At typical distances the acquisition sequence can happen very quickly and you may simply hear the high frequency tone and see the speed display immediately . A positive speed reading will be shown for an approaching vehicle, while receding vehicles are indicated with a negative reading . (Both the HUD and the back panel will show a "-" sign for receding vehicles.) The DragonEye Compact LIDAR will continuously update the target's speed reading at an approximate rate of 3 times-per-second as long as the trigger is depressed and the data quality is acceptable . While not required, it is recommended to track the vehicle for at least 1 second to establish robust confidence in the speed reading . 5.7 Speed Display Lock Once a desired speed reading is acquired, the operator can "lock" the speed reading on the side panel display by simply releasing the laser... -
Page 20: Range Mode
speed reading is locked, the unit will go into a sleep mode, turning off the HUD and displaying "Power-Save" on the side panel along with the locked reading . In the Power-Save state, a first laser trigger press and release will "wake" the LIDAR but retain the locked reading . A second trigger press will then clear the reading . This feature is intended to aid in preventing the operator from accidentally clearing the locked reading . 5.9 Range Mode The LIDAR system can be used to measure distances to a variety of targets . To enter Range Mode, press the Mode Button until the side panels displays: Figure 5.9 Side Panel indicating Range Mode active Use the aiming reticle in the HUD to select your desired target . Squeeze and hold the trigger down until a range reading is displayed in the HUD and on the side panel display . The trigger may be continuously held down as the unit is moved from target to target for quickly checking multiple ranges . The last range reading in the display is locked when the trigger is released . Range readings are displayed in tenths of a foot on the side panel and in the HUD up to 999 .9 feet (or 999 .9 m) . Above this, range readings are displayed to the nearest integer foot or meter . The maximum target distance is 3000 feet (914 m) which can be obtained from highly reflective surfaces such as retro-reflective road signs or vehicle tail lights/license plates . The range to non-retro- reflective targets will vary depending upon their infrared reflectivity . -

The side panel will also display the indication "Approach" or "Recede" to indicate that a vehicle has been targeted traveling in a direction opposite to that of the Filter . -
Page 24: Differential Distance: Lidar In English Units (Mph)
6.5.1 Differential Distance: LIDAR in English Units (MPH) The (MPH) Differential Distances Test uses two fixed targets separated by a precisely known distance . Using the LIDAR's range function to determine the separation between the targets, coupled with the internal acquisition period of the LIDAR's speed mode, the test provides a simulated speed reading (in MPH) which should be double the target separation measured in feet . Use two flat targets, approximately 2 ft x 2 ft square, painted flat white . Place the targets at precise distances from a "zero" point where the LIDAR will be positioned . The targets should be set at integer feet values from the LIDAR zero point and should be approximately 25 ft apart . Recommended target distances are 50 .0 ft and 75 .0 ft from the LIDAR unit . Ensure the front end of the LIDAR unit is positioned exactly at the zero point, using a tripod if necessary . On the LIDAR unit, press the Menu button then use the up/ down arrows until "Diff Distance" is displayed . Press Enter Carefully obtain a range reading from the first target and then press Enter . Carefully obtain a range reading from the second target and then press Enter . The LIDAR will then display the simulated speed on the rear display . The speed reading should be within +/-1 MPH or twice the range separation as measured in feet . For example, using the target distances of 50 .0 and 75 .0 ft, the simulated speed reading should be 2 x 25 .0 = 50 MPH +/-1 MPH . -
Page 25: Differential Distance: Lidar In Metric Units (Kph)
6.5.2 Differential Distance: LIDAR in Metric Units (KPH) The (KPH) Differential Distance Test uses two fixed targets separated by a precisely known distance . Using the LIDAR's range function to determine the separation between the targets, the KPH Differential Distance test provides a quick check of the LIDAR's ability to measure the distance between two targets . Use two flat targets approximately 0 .5 m x 0 .5 m square, painted flat white . Place the targets at precise distances from a "zero" point where the LIDAR will be positioned . The targets should be set at integer feet values from the LIDAR zero point and should be approximately 10m apart . Recommended target distances are 20 .0 m and 30 .0 m from the LIDAR unit . Ensure the front end of the LIDAR unit is positioned exactly at the zero point, using a tripod if necessary . On the LIDAR unit, press the Menu button then use the up/ down arrows until "Diff Distance" is displayed . Press Enter Carefully obtain a range reading from the first target and then press Enter .

If the LIDAR does not pass the test, carefully recheck the distances and reposition the targets and LIDAR if necessary then repeat the test . If the unit continues to fail the test, please contact customer... - Page 26 Timed Distance Shoot Object Figure 6.6 Side Panel indicating Timed Distance Mode active The operator may now enter the reference distance in feet (meters) between the two reference objects using the up/down arrows . Alternatively, the operator may shoot the two reference points to determine the distance to be traveled . • The reference distance must be at least 200 feet (60 meters) . • If the operator elects to shoot the distance to the reference objects, please ensure both reference points are on one side of the operator and in a straight line with the operator's position . The LIDAR will subtract the two readings to determine the distance . To shoot the distances, simply aim at the longer range reference object first and pull the trigger to obtain a distance reading . Release the trigger to lock in the distance reading . If you are not satisfied with the reading, you may simply aim and shoot the first reference object again . Once you are satisfied with the reading, press Enter . The unit will prompt you to shoot the second reference object . If the second reference object is located where you are standing with the LIDAR, simply press Enter . Otherwise shoot the second reference object and press Enter when satisfied with the distance reading . The unit will show the distance between the reference objects .
