| 摘要 |
The present invention relates to a radiation sensor for determining the direction of incident radiation, which is designed to be able to measure via only one amplification path, within a dynamic range from the sensitivity limit of photodiodes included in the sensor to far above their saturation level. This is made possible by the sensor comprising a number of equally large resistors (R) in a resistor chain between two tapping points (A1, A2) for sensor signals, a number of photodiodes (D) which are connected between the junction points between the resistors in the resistor chain and a bias source (Bias), the photodiodes being equidistantly spaced from each other along a line (2) in a plane within which the angle of incidence is intended to be measured, and an optical element (1, 3, 4) which causes incident radiation to illuminate different parts of the line of photodiodes (D), i.e. the detector row (2), in dependence on the direction of incidence of the radiation.
