CHARACTERISTICS OF A PRISM-PAIR ANAMORPHIC OPTICAL-SYSTEM FOR MULTIPLEX HOLOGRAPHY

By incorporating a prism pair in an optical system for multiplex holog raphy, the 2-D image for holographic recording can be compressed in on e direction with respect to the other direction. Hence, a cylindrical lens with smaller aperture can be used. The effects of the prism pair on the image of the original object and on the real image of the illum inating source point are analyzed. The aspect ratio of the image for h ologram recording can be continuously varied with the least root mean square error of the object. Experimental results confirming the result s of computer simulation are also provided. (C) 1998 Society of Photo- Optical Instrumentation Engineers. [S00913286(98)02410-6].
