A scalable sensor for wide field detection (imaging) of low contrast amplitude-modulated light has been fabricated in a standard CMOS process. The sensor has a randomly addressable array of 64 × 64 feedback buffered photodiodes. Any row of the photodiode array can be connected to 64 independent dual-phase lock-in detection channels allowing two-dimensional phase sensitive imaging without mechanical scanning.
