Abstract

Injecting a small fraction of the excitation pulse directly into the photomultiplier allows one to make a simultaneous recording of the instrument response function along with every sample measurement in time-correlated single photon counting procedures. The reference path is several nanoseconds shorter than the sample path, so the two signals are distinguishable. By this innovation, one can correct for drift in either the excitation pulses or the detection system including photomultiplier and electronics.
