Abstract
A system and method for measuring photons utilizing a low-power light source modulated with a code sequence to interrogate a sample of interest. Preferably a portion of the scattered light from the sample is detected by a photo-detector. A correlation of the photo-detector signal and the code sequence produces an estimate of the distribution of flight times for photons traveling from the source to the detector.
