Paper Abstract

The record of the interference pattern of the object wave and the reference wave is done by the application of high resolution photoplates in holography. After developing the photoplate the reconstruction of the object wave can be realized illuminating the hologram by the reference beam. In digital holography the photographic process is eliminated for the interference patterns are recorded by a CCD camera and the reconstruction can be done virtually using a computer. In general in-line reference beam is used coding the phases for the low resolution of the available CCD devices. The phase-shift technique (or application of two reference beams) can be applied to recover the phase and the amplitude of the image wve at the plane of the CCD matrix. The FFT algorithm is widely used for the reconstruction. Now it is proposed to apply the Monte-Carlo method simulating the diffracted wave to get the intensity distribution at the image plane. The application of Monte-Carlo simulation has a drawback, that is it can be slower than FFT, but its advantages can be significant, namely the intensity pattern of the diffracted wave can be determined along an inclined plane, just a part of the object can be examined if it is required and additionally there are no difficulties in extending it to phase holograms and 3-D objects.
