Abstract

The mechanism of speckle interferometer output signal forming for biovibration measurements is discussed. Statistical characteristics analysis of output signal amplitude is carried out. The factors creating parasitic amplitude-phase modulation of the output signal are investigated. The possibility of differential homodyne speckle interferometers application in Tibetan pulse diagnostics is shown.
