Laser radar guns measure the time it takes for infrared light to leave its source, reach a car, rebound off, and go back. These tools can determine how far distant an object is by multiplying this time by the speed of light. Because this type of radar sends out many bursts of light to determine several distances, the system can determine how fast the car is moving by comparing these samples. However, since laser speed detectors have a much more focused beam and sense lasers over great distances, police force laser guns are usually more difficult to avoid. While modern radar detectors often include a light-sensitive section that detects these light beams, the detector (and thus car) is more often than not already in the beams sights. While conventional detectors worked by alerting the driver to the existence of the radar or laser, the last few years have seen a rise in radars that also give out a blocking signal. This signal duplicates the original signal from the law enforcement radar gun and mixes it with extra radio noise, which confuses the radar receiver, and prevents the police officer from preventing an exact speed reading. Some detectors also use a laser jammer, or light emitting diodes (LEDs), that produce a light beam of their own. This beam prevents the receiver from recognizing any reflected light to get a clear reading on the vehicles speed. Even if you get a speeding ticket, it is still possible to argue your case against the ticket if the evidence was obtained using radar. discount radar detector
