Abstract:

A number of configurations of a Doppler velocimeter based on a semiconductor laser with a fiber channel have been implemented and the main parameters related to the fiber specificity of the outer arm of the optical system were analyzed. The efficiency of a homodyne optical system with a semiconductor laser as a radiation source and a fiber channel in the outer arm of the velocimeter in the velocity range of 0.1–100 mm/s is demonstrated. The maximum signal-to-noise values at the Doppler shift frequency of more than 15–20 dB allow us to conclude that it is possible to implement an effective system for measuring the velocity of scattering objects, provided that there is an additional pre-amplification in the signal processing channel and that the noise excitation of the laser emitter is prevented.
