abstract = "A detection system for detecting fluorescence lifetime includes an excitation light source configured for repeatedly generating pulsed excitation light, and a detector. The detector has a single-photon detection circuit; a pulse-inhibit circuit for rejecting detected photons that occur outside each one of a series of measurement time windows, each subsequent measurement time window starting after a subsequent excitation light pulse has stopped, and stopping before a next excitation light pulse is generated, each measurement time window having a measurement window period; and a switched-capacitor circuit having an input terminal for receiving a voltage ramp signal that is restarted with each new measurement window period. The switched-capacitor circuit is configured for repetitively computing an average voltage. The switched-capacitor circuit has a node for outputting the computed average voltage as a measure of the fluorescence lifetime.",
