摘要

A sensor device is described being designed to detect the phasetransition ofat least a part of a test material from the solid phase to the liquid phase. The sensor device comprises a light source (1) for initiating the phase transition for example by heating up the test material (10) by means of the emitted transition light (7). Further, the sensor device comprises a light detector (8) detecting detection light (6) thrown back by the solid phase of the test material (10) and subsequently detection light (6) thrown back by the liquid phase of the test material (10) afterat least a part of the test material (10) is melted by the transition light (7). The comparison of the signals received by the light detector (8) enables the detection of a phase transition of the test material (10) heated up by means of the light source (10). Examples of test materials (10) are ice and fat. Possible applications are the detection of ice in the automotive or aircraft industry.
