Laser Sensor

Laser Sensor

Principle: The emitting part of the laser sensor is a 180KHz oscillator emitted by an oscillator tube, amplified by a triode, the laser tube emits light, and the receiving part receives the returned light intensity from a matching 180KHz receiver tube. Since the laser sensor uses modulation processing, the receiving tube can only accept the reflected light of the same frequency, so the influence of visible light on the reflected laser can be effectively prevented.
