Research Abstract

We designed the hardware to accelerate a computer-generated hologram (CGH) algorithm and implemented it to a middle-scale (300,000 gates) programmable logic device (PLD). The chip could calculate CGH in parallel of 27. Using the chip combined with a high-resolution liquid-crystal display (LCD), we developed a portable one-unit system for electroholography. We implemented the chip and the optical setup including the LCD panel on one board. The fine minute LCD panel used here had the pixel pitch of 12 μm and the resolution of 800 × 600. We use the board by connecting to a personal computer (PC). The host PC sends the object data to RAM (Random Access Memory) on the board. The object data are converted to the hologram data by the special-purpose computational chip and are sent to the LCD panel directly.We used a light-emitting diode (LED) as the reference light source. The reference light from the LED is incident to the LCD panel and finally we obtain the reconstructed three-dimensional (3-D) image. We adopted a universal serial bus (USB) as the interface between the one-unit system board and PC, since USB is a standard interface, also compatible with notebook-type PCs. We also implemented the interface controller on the same board.
Next, we developed the printed circuit board (PCB) of the above system. In the PCB, we divide the CCH calculation circuits and the other circuits into two chips, since the PCB has the larger capacity for chips. The calculation chip could calculation CCH in parallel of 39 at 80 MHz, whereas the hand-made board was operated at 33 MHz. We are going to construct a parallel system by use of the PCB boards.
