We have developed a new vision chip for optical wireless communication systems. The vision chip can detect the positions of communication terminals and receive optical signals from multiple terminals concurrently by use of an image senser mode and a communication mode, respectively. We have designed and fabricated a 50x50-pixel vision chip in a standard 0.35 micro meter CMOS technology. We have verified the communication speed of 50 Mbps Mbps and transimpedance gain of about 320 kilo ohm.
