Laser tachometer

Laser tachometer The laser tachometer reads the optical pattern from a disc’s position at any time or from a dashed band by using the reflex method and makes it available as a TTL pulse train. The tachometer also outputs a speed-proportional frequency, similar to the scanning of a gear wheel with a magnetic sensor. To facilitate the positioning of the sensor head, the wavelength is in the visible range so that the position of the measuring spot appears as a red dot. To process different reflection factors, the electronics are equipped with a signal processor which continuously monitors the received light.
