Research output: PatentPatent


An apparatus comprises a semiconductor single-photon avalanche detector, and a counter. The detector performs detections of photons of optical radiation caused by an optical excitation pulse to the object. The counter measures timing of each detection made in the detector with respect to the excitation pulse causing the detected photons, and performs at least one of the following: forming a number of Raman detections, forming a number of fluorescence detections. Forming the number of the Raman detections is performed by eliminating an estimate of a number of fluorescence photons in the measurement. Forming the number of the fluorescence detections is performed by eliminating an estimate of a number of Raman photons in the measurement. The estimates are formed in a predetermined manner from the number and timing of the detections.
