    Abstract: In embodiments a detection system includes a detector configured to provide a received signal and a processing circuit configured to provide a plurality of quantized signals, each quantized signal being associated with a respective threshold level, and each quantized signal being representative of portions of the received signal in which a signal level of the received signal is greater than the respective threshold level and to provide an encoded signal based on the plurality of quantized signals, the encoded signal including a first plurality of first encoded signal values being representative of the portions of the received signal in which the signal level of the received signal becomes greater than one of the threshold levels, and a second plurality of second encoded signal values being representative of the portions of the received signal in which the signal level of the received signal becomes less than one of the threshold levels.

    Abstract: A light module includes an excitation radiation source designed to emit an excitation radiation having a polarization, at least one first phosphor, an output, at which an output signal is providable, at least one first polarization beam splitter, a first polarization modulator arranged serially between the radiation source and the first splitter. The first modulator is designed to modify the polarization of the radiation source depending on a control signal. The first splitter is designed to split the radiation incident on it depending on the polarization between a first and a second of two optical partial paths connected in parallel with one another. The first optical partial path includes the at least one first phosphor and ends at the output of the light module. The second optical partial path, whilst bypassing the at least one first phosphor, ends at the output of the light module.
