Measurement of phase functions of 1-D and 2-D Fourier spectra
By using a coherent optical information processing system with two orthogonal polarization channels we have measured the Fourier phases experimentally for one and two dimensional real objects. For a shifted slit and a shifted square, the Fourier phase values measured by experiment are in agreement with the calculated phase values quite well. Another object is a binary alphabet, the real and imaginary part of its Fourier spectrum has been investigated.
