Abstract: A sensing device includes a first array of sensing elements, which output a signal indicative of a time of incidence of a single photon on the sensing element. A second array of processing circuits are coupled respectively to the sensing elements and comprise a gating generator, which variably sets a start time of the gating interval for each sensing element within each acquisition period, and a memory, which records the time of incidence of the single photon on each sensing element in each acquisition period. A controller controls the gating generator during a first sequence of the acquisition periods so as to sweep the gating interval over the acquisition periods and to identify a respective detection window for the sensing element, and during a second sequence of the acquisition periods, to fix the gating interval for each sensing element to coincide with the respective detection window.
