Abstract
Computer Generated holograms offer a wide variety of applications, specifically in the synthesis and processing of real and synthetic images. In this paper we examine and demonstrate the major aspects of recording these holograms using an ejectron beam exposure system (MEBES). Holographic patterns stored in memory can be recorded directly onto an electron sensitive resist with a IX format, thus requiring no reduction techniques. The MEBES system can record holograms as large as 12 cm. by 12 cm. square with a resolution of 500 cycles per mm. without significant distortions. The amount of information required to record such a hologram can far exceed 15 gigabytes. But by the method presented this process can be divided into manageable parcels (260k bytes) which are then combined to form a large scale hologram. The end effect of this project was to demonstrate that computer generated binary holograms can be recorded using an electron beam exposure system (MEBES). The results of this technique have been modest but more important, offer a promising future.
