Patent ID: 6875974

Claim:
A device for detecting the angle of incidence of radiation on a radiation incidence surface, comprising: at least two first pairs of photodiodes comprising first photodiodes arranged along a first axis and connected in series in a pair-wise manner, each of the first photodiodes comprising a space-charge zone having a space-charge zone face oriented towards the radiation incidence face, a shading mask arranged at a distance above the space-charge zone faces of the first photodiodes and comprising radiation-transmitting areas, each radiation-transmitting area being assigned to the space-charge zone faces of the two first photodiodes of a first pair of photodiodes and when viewed in the direction of the normal of the radiation incidence face, the degree of overlapping between a radiation-transmitting area and its assigned space-charge zone faces in the direction of the first axis being different for at least two of the first pairs of photodiodes, and an evaluation unit for monitoring the photocurrent and/or the photovoltage of each first photodiode of each first pair of photodiodes and for detecting, on the basis of a comparison of the photocurrents and/or the photovoltages, the angle of incidence under which the component of the radiation which in the projection is directed parallel to the first axis impinges on the radiation incidence face.
