ABSTRACT:
A modulator (2) is provided for the periodic frequency modulation of laser light. Disposed downstream of a photo detector means (13, 14) is an electronic signal processing means (15, 18, 20, 20', 21, 21', 22, 26, 27) for detecting and evaluating the amplitude modulation of electric signals caused by frequency modulation of the laser light.
