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 0.18 ¿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.
