Abstract
We developed a one-unit system for electroholography, which consists of a special-purpose computational chip and a high-resolution, reflective mode, liquid-crystal display panel as a spatial light modulator. We implemented them on one board whose size is approximately 20 cm × 20 cm. The chip makes a computer-generated hologram whose size is 800 × 600 at nearly real time (~0.5 s) for an object consisting of 1000 points. The pixel pitch of the display panel is 12 μm, and the resolution is 800 × 600. It reconstructs a three-dimensional motion image whose size is approximately 3 cm × 3 cm × 3 cm. The system can be readily scaled up, since the units consisting of the chip and the display are easily set in parallel.
