Abstract

We present a digital instrumentation method of time-correlated single-photon counting (TCSPC). The pulsed signal of a single-photon sensitive photodetector is digitized by a high-speed analog-to-digital converter and digitally processed for determination of the photon detection times. We found that our digitally implemented TCSPC (dTCSPC) provides a smart way of discriminating valid photon pulses for the reliable measurement of fluorescence lifetimes and time-resolved spectroscopy.
