Paper Abstract

We propose an optical implementation of iterative Fourier transform algorithm using a spatial light modulator and phaseshifting digital holography technique. It is shown that the optically implemented iterative Fourier transform system can improve quality of target diffraction images in real time by the same way the numerical iterative Fourier transform algorithm does in the numerical simulation. In the proposed implementation, the wave front of diffraction field is directly measured by the phase shifting digital holography technique and the phase modulation of light field is performed by a phase-type spatial light modulator. The feasibility and more general applicability of the proposed implementation of the iterative Fourier transform algorithm for digital holography techniques are discussed.
