摘要

The device has a transmitter (1) producing a series of measuring light pulses (2) with a pulse repetition rate greater than 0.16 MHz. An evaluating device (6) comprises a filter filtering electrical signals in unconverted, received measuring light pulses (4) of a target object (3) at a receiver (5). Bandwidth of the filter is less than that of the light pulses. The evaluating device scans the light pulses with respect to small phase shifts, which are smaller than a sample period. An entire phase shift of the light pulses is smaller than or equal to the sample period. The transmitter is formed as a semiconductor light source such as laser diode or LED. The receiver is formed as a positive intrinsic negative (PIN) diode or avalanche photo diode (APD).
