Abstract

Optical holography, typically, uses laser light as coherent source for interference pattern construction and holographic registration. Interference simulation and pattern printing has been possible through computer aids and plotter printing with photographic reduction. With powerful computers and modem laser printers, computer generated holograms can be demonstrated in a simpler way. During this work, computer software was developed and Fourier holograms were produced from simple digital images. The computation process uses a Fourier Transform algorithm to simulate the interference pattern, which is then transformed into a binary matrix. The software was developed to generate also dynamic holograms from an array of digital movie frames. In this paper the software will be presented and the visualization setup and some results will be analysed.
