Abstract
The invention relates to a sensor device comprising an array of detectors. In such a detector array, it is difficult to read out weak electric signals, especially if there are many detectors. The invention solves the contemplated problem by using a device in which each detector consists of a radiation-sensitive component included in an oscillator, for example a resistor or a capacitor included in an RC oscillator, whose frequency is used as a measure of the detected quantity.
