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 640Ã—240 image pixels and 640Ã—240 LPR cells implemented with 0.18 Â¿m CMOS technology. Both imaging and 60 fps optical communication at the carrier frequency of 1 MHz are successfully performed. The measured signal amplitude and the calculation results of photocurrent shows that the spatial optical communication up to 100 m is possible.
