Abstract
The use of transmission grating for measurement of rough body tangential velocity is discussed. The possibility of obtaining narrow component in the spectrum of scattered from rough surface and transmitted through the grating radiation is confirmed both theoretically and experimentally. The availability of a narrow component in the spectrum of scattered radiation with (Delta) f/f < 2 10-2 enables one to measure tangential velocity of the diffuse object within +/- 0.5% accuracy.
