Abstract
The invention relates to a method and device for calibrating or testing the detector surface (10) of a measuring device (1) detecting hydrometeors. According to the method, impulses are focussed on the detector surface (10) in a controlled manner, the responses caused by the impulses, detected by the detector of the measuring device (1), are measured, the measurement values of the responses are compared with the target values and the required corrections to the settings of the measuring device (1) are analyzed, and the measuring device (1) is adjusted on the basis of the analysis. According to the invention, an electromagnetic radiation pulse (70) of short duration is focussed on the detector surface (10), whereby this causes a thermal-expansion reaction in the detector surface (10), detected by the detector.
