Abstract
In the previous communication1 we have realized the measurements sensitivity of small phase modulation or small modulation of the re- search object anisotropy on the the shot-noise level and equal -.17 -1/2 2 . The photoelastic modulator of phase shift 1.10 rad/Hz and differential registration scheme have been used in these measure- ments. The following analysis providesthe conditions sufficient for the noise suppression below the shot-noise level by the use of squeezed states of light in the measurements schemes of such type. Consider an optical mixing device (beamsplitter, intrferometer etc.) with two input and two output channels (see fig. la).
