Abstract

The work represents a new method of measurement of displacements, based on the coherent interaction of a surface acoustic wave (SAW) and a stationary reference grating (SRO) which modulates the intensity of an optical beam at the same frequency as the SAW. The experimental setup showed, that the resolution was defined by the noise level of electronic part and it reached 0,0IMm when the phasic method of measurement was used.
