Abstract :
A CMOS position-sensitive photodetector (PSD) optimised for outdoor applications is presented. The PSD operates similarly to a four quadrant PSD, but instead of being fixed, its gap tracks the light spot as it moves. Test results show a significantly better performance as compared to conventional PSDs
