摘要： A histogramming readout circuit is described. The readout circuit comprises a time to digital converter (TDC) configured to continually report time-stamps defining an arrival time of a laser clock and a signal output from a photosensor. Memory is provided for storing TDC events. A programmable processor is configured to implement a state machine. The state machine being operable to saves a time-stamp when a TDC event is detected; determine the time of flight of each of the photons detected by the photosensor; using each calculated time of flight to address a memory location; building up a histogram of the TDC data values using the memory locations as time-bins; maintaining a pointer to a maximum memory location where the highest number of TDC event resides. A calculator is operable to read the value of the maximum memory location and one or more adjacent time-bins either side for processing.

摘要： There is provided an imaging device comprising a plurality of photodetectors in a predetermined spatial arrangement. Each photodetector is connected to a different predetermined pair of first and second readout channels so that the spatial position of an active photodetector can be determined from the corresponding pair of active readout channels. The number of readout channels is less than the number of photodetectors. For each photodetector its first readout channel is shared with a first plurality of other photodetectors of the arrangement, and its second readout channel is shared with a second plurality of other photodetectors of the arrangement. A first option is that the second plurality is greater than the first plurality for at least some of the photodetectors, with the position of an event occurring at one of the photodetectors being determined from the active first and second readout channels, and with the energy and/or timing of the event being determined from the active firstreadout channel. A second option is that at least some of those photodetectors sharing the same first channel are not adjacent in the arrangement. A third option is that the photodetectors are silicon photomultiplier detectors. The first to third options can be used separately, in isolation, or in any combination.

摘要： A light sensor module (1) comprises a plurality of light sensing elements (2) arranged on a substrate (4). The module is operable in a mode of operation in which the elements cooperate in use to produce a combined output signal indicative of an overall level of light falling on the elements (2). In one example, each element (2) comprises a light input surface (16) arranged to face away from the substrate (4) and an opposed surface (18) arranged to face towards the substrate (4). Each element (2) is arranged to make electrical connection (8) to the substrate (4) through the opposed surface (18), leaving the sides (19) of the element (2) substantially free. This enables adjacent elements (2) to sit closely together to form a close-tiled arrangement of the elements (2) covering a large area.
