Paper Abstract

By using a Fourier-optical system with two orthogonal polarization channels we have separated the real part and the imaginary-part and measured the phase function of the Fourier spectrum. For a real asymmetrical object function f(x,y);(Fig. la), its Four-ier spectrum is a complex function of the spatial frequency and the phase function is the goal for us to measure experimentally. First, related to the original function f(x,y) we construct a new function f'(x,y) (Fig. lb) which is symmetrical with respect to the origin of the coordiate axes
