Smart pixels permit rapid signal processing through the use of integrated photodetectors and processing electronics on a single semiconductor chip. Smart pixels with smart illumination can increase the dynamic range and functionality of smart pixels by employing optoelectronic feedback to control the illumination of a scene. This combination of smart pixels and optoelectronic feedback leads to many potential sensor applications, including normalized differential detection, which is modeled and demonstrated here.
