Abstract
This paper presents a CMOS imager and 2-D Light Pulse Receiver (LPR) array for car-to-car and road-to-car spatial optical communication. Using the prototype sensor with 640×240 image pixels and 640×240 LPR cells implemented with 0.18μm CMOS technology. Both imaging and 60fps optical communication at the carrier frequency of 1MHz are successfully performed. The measured signal amplitude and the calculation results of photocurrent shows that the spatial optical communication up to 100m is possible.
