A laser pulse is first emitted by a laser emitting diode aimed at the target. After reflection from the target the laser light is scattered in all directions. Some of the scattered light is returned to the sensor receiver, where it is received by the optical system and imaged onto an avalanche photodiode.
diode. An avalanche photodiode is an optical sensor with internal amplification so that it can detect extremely weak light signals and convert them into corresponding electrical signals. A common example is the laser
distance sensors, which determine the distance to a target by recording and processing the time elapsed from the time the light pulse is emitted to the time it returns to be received. Laser sensors must determine the transmission time extremely accurately because the speed of light is so fast.
Unlike traditional background suppression sensors, the LA-Z series of intelligent CMOS background suppression sensors, which adopt the new array PD technology and triangulation principle, achieve black-and-white equidistant and are completely independent of colour, and are dedicated to stable detection.
The LA-Z series of intelligent CMOS background suppression sensors is completely colour-neutral and is dedicated to stability detection, demonstrating outstanding performance!
