Abstract
A method for improving dynamic range of a device for detecting light includes providing at least two detection regions. The detection regions are each formed by an array of a plurality of single-photon avalanche diodes (SPADs) and the detection regions each comprise at least one signal output. A characteristic curve is determined for each of the detection regions. The characteristic curves are combined with one another and/or offset against one another in order to obtain a correction curve and/or a correction factor.
