Abstract
We developed an electroholography unit for a three-dimensional display, which consists of a special-purpose c-omputational chip and a high minute reflective liquid-crystal display panel. We implemented them on one board whose size is approximately 28 cm x 13 cm. The chip can compute a computer-generated hologram whose size is 800 x 600 at nearly real time (0.15 s) for an object consisting of 400 points. After the calculation, the LCD panel displays the computer generated hologram made by the chip, and we can observe a three-dimensional (3D) motion image whose size is approximately 3 cm x 3 cm x 3 cm. The pixel pitch of the display panel is 12 μm, and the resolution is 800 x 600. To obtain a 3D motion image with large viewing zone and image size, we need to parallelize the unit. The unit can be readily scaled up, since the units consisting of the chip and the display are easily set in parallel
