<title>New approach to the interactive holographic display system</title>

Abstract

This paper presents a new type of the interactive holographic display system which features both dynamic and precisely detailed imaging.The main discussion is on synthesis ofelectronic holograms and optical holograms. Electronic holograms have benefits of dynamic imaging of computer generated three dimensional objects in essence. On the other hand, conventional optical holograms are known to be suitable for detailed and precise imaging. Considering that many images typically contain objects which dynamically move around on the still background, synthesis of electronic holograms and optical holograms has high potential that the currently limited electronic holograms are applied to wide range of applications.The second discussion ofthis paper is about the possibility ofproducing computed holograms in real time. Computation time of generating holographic fringe patterns with a parallel computer CYBERFLOW is considerably reduced by using techniques such as parallel computation with and within 64 processing elements, vectorized computation, scalar computation simultaneously in parallel with vector computation, and simultaneous computation with data transfer to the output display device. The obtained result is 84.7 times as fast as a conventional computer and promises the possibility of the real time computer generated holograms.
