Abstract
A photodetector arrangement having adjustable output, comprises a photodetector having an array of pixels wherein each pixel. The pixels are arranged to convert electromagnetic radiation into an analog detection data signal, respectively. A readout circuit is coupled to the photodetector and comprises a receiving component and a combining component. The receiving component is arranged to read out detection data signals, to select at least one detection data signal depending on a control signal and to adjust gain and polarity of the selected detection data signal. The combining component is arranged to combine the detection data signals into one or more output signals to be provided at one or more output terminals. A control unit is coupled to the readout circuit via a control terminal and is arranged to provide the control signal at the readout circuit depending on a set of instructions.
