Abstract: A photodetector device includes an avalanche photodiode array substrate. A circuit substrate includes time measurement circuits and a clock driver. Each of the time measurement circuit includes a delay line unit, and is arranged to acquire, from an operation result of a delay line, time information indicating timing at which a pulse signal is input from a corresponding avalanche photodiode. The delay line unit is arranged to initiate an operation of the delay line in response to input of the pulse signal to the time measurement circuit, and to stop the operation of the delay line in response to input of a clock signal from a clock driver to the time measurement circuit, and is arranged to detect a time interval shorter than a cycle of the clock signal by the operation of the delay line.

Abstract: Signal processing method for histogram generation, and corresponding device and use. The method generates the histogram from a plurality of event detectors that generate event signals as a response to external events, and are connected to a current injection module which is connected to a plurality of capacitors, wherein each histogram bin is univocally assigned to a capacitor. The method includes: during an event time interval corresponding to a bin, the event detectors generate event signals as a response to external events; the current injection module detects said event signals and, for each event signal, generates a corresponding current signal, which is injected in a capacitor assigned to said bin, and stored therein; repeating steps for each successive bin of said histogram; and reading the charge accumulated in each of said capacitors.
