Summary:A readout chip for single photon counting has a plurality of N individually working channels each assigned to a respective detector diode. Each channel has a counter designed as a binary counter having a length of M bits and a number of programmable bits. Further, the readout chip has a serial shift register or parallel data input register for entering values for the counter and the programmable bits, and a number of data output shift registers each having a number of K data outputs. Means are provided for selectively multiplexing each of the K data outputs onto a selectable bit of the data output shift register.
