In accordance with an embodiment, a circuit includes a photodetector (PD) array including a plurality of electrically isolated PD sections. Additionally, the circuit includes a switching matrix that includes a plurality of inputs and a plurality of outputs, and that can be selectively configured in a plurality of different switch configurations. Each of the electrically isolated PD sections is adapted to detect light (if any) and provide an electrical output signal, indicative of the light detected by the PD section (if any), to a different one of the inputs of the switching matrix. The switching matrix is adapted to combine the electrical output signals provided by the electrically isolated PD sections in a plurality of different manners, in dependence on which of the plurality of different switch configurations is selected.
