Abstract: A sensor device comprises an array (10) of photodetectors. A multiplexer circuit (20) is connected to the array (10) of photodetectors and provides dedicated output paths for each photodetector in the array (10), respectively. Furthermore, the sensor device comprises at least one control terminal (21). An array of time-to-digital converters (40) is connected to output terminals (22) of the multiplexer circuit (20). Depending on a control signal to be applied at the at least one control terminal (21), the multiplexer circuit (20) is arranged to electrically connect only the output paths of a subarray (11) of photodetectors to the output terminals (22) of the multiplexer circuit (20).
