Abstract

A system includes an assembly, a pinhole array, and a processor. The assembly includes a K by L photodetector array comprising a plurality of photodetectors and configured to detect light that exits a body at a second location after the light enters the body at a first location different than the second location and scatters within the body, and output a plurality of electronic signals representative of the detected light as a function of time. The pinhole array has a K by L array of pinholes configured to be aligned with the photodetectors and is configured to allow a certain amount of light to be incident upon each of the photodetectors. The processor is configured to generate a correlation map that includes a plurality of spatiotemporal correlation measure values corresponding to the light detected by the photodetector array.
