two methods of initial estimates are proposed: (1) using real time image subtraction scheme and a micro motion compensation mechanism to take zero constantly as initial estimates;
with a phase grating located at fourier frequency plane, optical image subtraction is obtained as a result of the coherent superposition of the zeroth and the first order of the diffracted light.
