How the LRC 100 works

LRC 100 is an active laser detector and laser jammer. It transmits a series of laser light pulses that prevent a laser gun from calculating a vehicle’s speed. LRC 100’s receiver is designed so that it will not give false alarms, but when a laser gun is pointed at your vehicle, LRC 100 responds.

What happens? When LRC 100 acquires a laser gun, it immediately returns a 5-second jamming signal, gives the driver a visual warning, and emits a 100dB audible alert. For 5-seconds, the laser gun’s display will not produce a speed reading, more than enough time for the driver to check, and if necessary, adjust vehicle speed safely. The diode then shuts down, and the jammer acts as a passive detector for the next 60 seconds while you clear the laser speed trap. After recycling, the LRC 100 is ready to do its job again.

Laser guns typically use narrow spectral filters that eliminate interference from nonlaser sources, such as inexpensive light-emitting diodes (LEDs), headlights, and solar glints. LRC 100 uses an indium gallium arsenide laser diode similar to the one used in laser guns. This laser diode transmits a powerful laser signal at the same wavelength the laser gun’s are designed to receive. Due to the strength and timing of LRC 100’s signal, the laser gun ignores its reflections, and tries unsuccessfully to calculate the speed of the LRC 100’s signal.

How a Laser Gun Works

A laser gun works best when aimed at highly reflective surfaces such as headlights or front license plates. Its internal computer measures the time it takes for the pulse it sent out to return. After doing this many times, it can display how the target vehicles distance is changing with time (speed). A laser gun usually transmits about 100 individual pulses of infrared light in the one-third second it takes to calculate a vehicle’s speed. With pinpoint accuracy, its narrow beam can pick out one vehicle in a group. This means the laser gun’s beam (signal footprint) is normally 3–4 feet wide at a distance of 1,000 feet. A radar beam’s wave-length is longer and, therefore, much wider. Laser detectors mounted on the windshield give little or no warning because they are outside a laser gun’s beam. If these detectors do sound an alert it could be too late. The laser gun may have already clculated the vehicles speed. Laser guns generally target between 600 to 1,200 feet. targeting vehicles at distances greater than 1,000 feet is very difficult.
