Laser based distance measuring system has optical system for regulating transmission coefficient |
摘要 |
The distance measuring system has a laser diode (3) and the output is fed through an optical fibre (4) to transmitter electronics (5) and to an interface that generates stray particles that are used as reference light source. A rotating attenuation disc (9) is moved to vary the transmission coefficient of the signal.
