Combination Photodetector Arrays for Extended Dynamic Range

A system comprising:

• a substrate;
• a plurality of single-photon photodetectors coupled to the substrate, wherein the single-photon photodetectors are arranged to detect light from a field of view;
• at least one additional photodetector coupled to the substrate, wherein the at least one additional photodetector is other than a single-photon photodetector, wherein the at least one additional photodetector is arranged to detect light from the field of view;
• and
• a controller configured to execute program instructions so as to carry out operations, the operations comprising:
• receiving a first photodetector signal from the plurality of single-photon photodetectors, wherein the first photodetector signal is indicative of light from the field of view detected by the single-photon photodetectors;
• receiving a second photodetector signal from the at least one additional photodetector, wherein the second photodetector signal is indicative of light from the field of view detected by the at least one additional photodetector;
• selecting a photodetector signal from at least two of:
• the first photodetector signal, the second photodetector signal, and a combined photodetector signal formed by combining the first and second photodetector signals;
• and
• determining an intensity of light in the field of view based on the selected photodetector signal.
