Abstract
A system includes a photodetector array and a processor. The photodetector array includes a plurality of photodetectors and is configured to detect light that exits a body and output a plurality of electronic signals representative of the detected light as a function of time. The processor is configured to sample the electronic signals output by the photodetector array at a plurality of delay times during a predetermined time period to generate a sequence of frames, apply a plurality of temporal-based and spatial-based correlation measurement operations to sample values in each of the frames, generate, based on the application of the temporal-based and spatial-based correlation measurement operations to the sample values in each of the frames, a plurality of spatiotemporal correlation measure values for the light detected by the photodetector array, and include the plurality of spatiotemporal correlation measure values in a correlation map.
