Paper Abstract

A new digital hologram data generation and recording method of computer generated holograms (CGH) is described in this paper. The application of using this automatic system can be for display, security and diffractive optical device. As an experimental example, an algorithm of a mathematic model of one-step setup was proposed for creating a white light reconstruction holographic stereogram. The experimental hologram size is 1cm x1cm using 16 perspective CG images, with 3200 pixel x 3200 pixel per each image. A new calculating algorithm was introduced for processing large quantity of data. In addition, a new high speed and high speed digital optical data recording method was applied in the recording process. The method achieves about 0.4 micron spot size resolution. A digital hologram of 1 inch x 1 inch size has been written in 5 hours by this method, where an incoherent single beam is used as the only recording light source. Experimental results show that the digital image processing as well as the recording method is successful and can be applied for display, security holograms, Kinoform and Diffractive Optical Element applications.
