These Components Are Used to Measure Speed

07.09.2016

Pulsed Laser Diodes and Avalanche Photodiodes


The measurement of speed is used by both athletes and the automobile industry in particular. Integrated into modern systems, the distance to the car ahead, for example, can be controlled, which significantly increases driving safety and comfort. This adaptive cruise control (ACC) is implemented using a light detection and ranging (LIDAR)-based sensor that calculates the position and speed of the car ahead via runtime measurements. The same technology is used by the police in speed traps that are carried out using a laser pistol.

The sensor consists of an emitter (pulsed laser diode, PLD) and a receiver (avalanche photodiode, APD).

As sender pulsed laser diodes are used. To make the beam invisible to the human eye, near infrared emitting PLDs are used. 905 PLDs are available with a peak power of up to 650 W; for distance and speed measurements in sports applications, low-cost versions with an output of a few tens of watts are completely sufficient. LASER COMPONENTS manufactures both versions in Canada.

The reflected signal is detected by a Si PIN or Si avalanche photodiode. LASER COMPONENTS‘ SARF500Fx series with integrated 905 nm bandpass filter is very popular for those applications as the filter suppresses all scattered light and sunlight.
