Abstract
A structure and method of operation of a fringe direct writing system to produce a hologram or the like. The apparatus is roughly classified into four parts: an illumination part; an image display and optical imaging part; an optically autofocusing part; and a two dimensional moveable stage part. The method of operation directly images a pattern, which is previously calculated by computer and displayed on the LCD panel, onto a recording material. This method affords the possibility to write a fringe pattern in a large region within a short period of time.
