Patent ID: 8803059

Claim:
Sensor for determination of an incidence angle of a radiation source, comprising: in a semiconductor layer, a diode assembly of avalanche photodiodes comprising a position sensitive detector, and an application specific integrated circuit for generation of analogue output signals that can be evaluated, a transparent distance layer for the adjustment of a distance, an aperture structure on the distance layer and comprising a defined opening in a non-transparent layer, and contact means for electrically connecting the sensor, wherein the diode assembly comprises n pairs of avalanche photodiodes with n=1, 2, 3 etc. arranged in such a way that the avalanche photodiodes are positioned axially symmetrically in relation to both axes x and y for the determination of the position of the incident radiation, and so that the opening of the aperture structure depending on the incidence angle of the radiation can be partly imaged on the avalanche photodiodes of this diode assembly respectively.
