A light sensitive detector arrangement contains a plurality of photosensitive detector elements, which in each instance have a multilayer structure of alternating positively and negatively doped photosensitive semiconductor material with a superlattice structure and control electrodes arranged vertically to the semiconductor layers and bordering on them on their front faces. To these a control voltage can be applied in order to control the spectral light sensitivity. An array contains in each case a predetermined number (for example three) of photo detector groups (E.sub.11 to E.sub.mm) of photosensitive detector elements (E.sub.111, E.sub.112, E.sub.113. . . respectively E .sub.mml, E.sub.mm2, E.sub.mm3). The control electrodes of the photo detector elements of each photo detector group are connected to variable voltage regulators (U.sub.1, U.sub.2, U.sub.3). Through the voltage regulators the upper and/or lower limit wavelength (.lambda..sub.o, .lambda..sub.u) of the photo detector elements of the discrete photo detector groups can be set differently and graded with respect to each other. A filter arrangement is provided having high pass or low pass function, the filter edge (.lambda. .sub.F) of which subdivides the spectral range of the discrete photo detector elements of the photo detector groups into an upper or lower effective spectral range (.lambda..sub.F -.lambda..sub.o3, .lambda..sub.F -.lambda..sub.o2, .lambda..sub.F -.lambda..sub.ol). Differential amplifiers can be driven with the signals of the photo detector elements of each photo detector group, the inputs of which can be driven by the spectral signals of the outputs of two adjacent photo detector elements, such that at the outputs of the differential amplifiers differentiable selected spectral signal responses occur.
