Abstract

The laser Doppler velocimetry measuring system on the basis of injection semiconductor cw laser has been investigated. The system is capable of analyzing the local velocity distribution of moving object in the range 1 mm/s - 5 m/s with the sensitivity threshold up to 0.1 nW and signal-to-noise ratio 30 - 40 dB for solid targets and 5 - 15 dB for dense aerosol flows.
