Paper Abstract

It becomes quite easy to calculate over one hundred million pixels computer-generated hologram of three dimensional objects, even with normal personal computers. On the other hand, it is not so easy to output the calculated result as a hologram that must have micron order resolution for practical three dimensional displays. It is possible to use the electron beam writer and the laser plotter, which are used to make masks for integrated circuits. However, these equipments are quite expensive and not suitable for personal use. There have been reported some results of compact and inexpensive direct fringe printing. They use a laser and an x-y stage, and the fringe pattern is written point by point, which takes very long time. We are developing area by area writing printer, which consists of the laser, the x-y stage and a liquid crystal panel as a spatial light modulator. A fractional part of the entire holographic fringe is displayed on the liquid crystal panel, and the demagnified image of it is recorded on a holographic plate. Then the plate is translated by the x-y stage to write next part of the fringe. The system configuration and preliminary results are described.
