摘要: A laser Doppler speed measuring apparatus comprises a laser light source, a photodetector, an FM demodulator, and an integrated filter circuit. A selector switch is interposed between the FM demodulator and the integrated filter circuit so as to ensure switching between an output of the FM demodulator and a terminal for directly receiving an external signal.
