Abstract
A photodetector includes a light receiving part having a plurality of light receiving elements, and a signal processing part that adds outputs from the light receiving elements and outputs the result. A plurality of measurements are performed while combination of effective light receiving elements among the light receiving elements in the light receiving part is changed. The results of the measurements are subjected to a compressive sensing process to determine an output signal of for each light receiving element or for each group of light receiving elements.
