Abstract
A sensor device is provided and includes an array of photodetectors. A readout circuit is connected to the array of photodetectors and provides dedicated readout paths for each photodetector in the array, respectively. Further, the readout circuit includes at least one control terminal. An array of time-to-digital converters is electrically connected to converter output terminals of the readout circuit. Depending on a control signal to be applied at the at least one control terminal, the readout circuit is arranged to electrically connect through the readout paths of photodetectors of a first subarray (11) to the converter output terminals of the readout circuit, respectively, thereby rendering the photodetectors of the first subarray active and photodetectors of a second subarray inactive.
