Abstract

A liquid crystal display (LCD) is very convenient as spatial light modulator and seems to be a promissing device for interfacing computers with holographic imagine. We discuss some of the potential applications such as transforming a computer displays to a coherent image, generating multiplex holograms from CAD-systems, and generating holographic read-only memories directly from computer displays. Other possibilities for the LCD device are fast control of slit-width and slit position in multiplex holography, and for the control of aperture position and size in facet holography. Optical properties of a transmissive LCD screen (640 x 200 pixels) has been tested. Application of the device for interfacing a CAD-system to a holographic camera for generating composite holograms (stereograms) are discussed.
