Paper Abstract

This paper gives an expression that describes correlation between sinusoidal —modulated signal and average of interference signal in sinusoidal phase-modulated heterodyne interference. The expression can be used for estimating frequency-modulated coefficient of LD(laser diode)and the influence caused by sinusoidal modulation for the intensity of output LD. Experiments are carried out. The correlation is also used for the distance, the displace and the surface profile measurement.
