Anti-laser and Lidar

1. Anti-laser and Lidar By Mego Easley Jake Landess and Andrew Newberry

2. Anti-Laser • Outer unit Sensor circuit special infrared lens that focuses laser light onto the detection amplification Circuit admits only lidar It admits impulses that are equal to the laser impulses

3. Anti-Laser Inner unit The Inner unit contains an audio visual and processing circuit In the center of the unit the processing unit recieves signals from the sensor circuit

4. How Lidar Works • The laser beam which is narrower then a radar beam, is how it can be used for heavy traffic • The moment the trigger is activated, lidar starts, and in the next .5 seconds it takes 50 measurements and calculates speed • Also the range of the lidar is decreased when the weather conditions are bad and the target area, and the licence plate reflection of the lidar is halved

5. Specs. Of AntiLaser • 85x22x40mm is the inner unit • 50x20x50mm is the outer unit • 904nm- laser wave length • 10,5V-15V- power • 300mA max. current consumption • 85 dB speaker volume • 1M laser class

6. Continued specs of Anti-Laser • LTI Marksman 20.20, Multilaser LTI UltraLyte, LR,100,100LR,200,200LR, COMPACT, LRB Multinova- Starlaser Robot-TrafficPatrol, V Sagem-Mester laser Stalker-Lz1 Laser Atlanta- Speedlaser,s,r,Stealth Mode Traffic Observer- LMS 291/221/04/05

7. Types of Speed Detection Systems • Radar devices, loop technology, light beams, video systems(fixed and mobile), and finally Lidar

8. Lidar • Lidar is Light detection and Ranging Lidar is a small laser that is focused on an object and then calculated in order to tell the speed an automobile is traveling at

9. Installation • The outer unit of the Anti laser is put on the front of the vehicle the outer is made to withstand many harmful conditions • The inner unit has to be put some were accesible and some where were you can turn it on and off very easily

10. Radar • Radar is an electronic tool which uses electromagnetic waves to detect and locate moving or fixed objects

11. Police Radar • Utilizes radio waves and the Doppler Effect • Police Laser Radar(Lidar) utilizes light waves and the pulse principle

12. Doppler Principle • States that the measured frequency of a wave is relative to the motion between the source and the observer

13. How Radar Works • The Radar Gun is used to send out radio waves of specific frequencies in a chosen direction • The waves bounce off objects and return to the radar gun(when the waves reflect it is known as Doppler Shift) • The radar gun computer then uses the frequency to calculate the speed

14. Radar Detectors • The idea behind them, are that they look for radar “beams” and find them before they can return a strong enough reflection to “illuminate” you • Radars are essentially microwave radio receivers that make noise or flash lights when they sense an incoming signal on specific frequencies

15. Radar Beam • The radar antenna transmits the signal in a directional beam similar to the configuration of a flashlight beam • Police traffic radar beam is conical in shape and continues outward indefinitely from the antenna until it is reflected, refracted, or absorbed
