Abstract
In this paper we analyze the probability density function of the super heterodyne signal obtained in a two-wavelength interferometer from the beat of a local oscillator laser beam with a speckled return beam The oretical investigation shows that, by using an increased number of spa tially one can improve noticeably the detection probability of the sup erheterodyne Experimental results obtained with a four-quadrant detect or are in good agreement with theory.
