ABSTRACT:
A detector comprises an infrared reflection layer and a diaphragm member, the infrared reflection layer and the diaphragm member facing each other, with a space intervening therebetween, and the diaphragm member comprises an infrared absorbable layer. A signal varies a distance between the diaphragm member and the infrared reflection layer, and thus a band of an absorbed wavelength is varied. The distance is varied by a voltage applied between a first conductive layer disposed at the infrared reflection layer side and a second conductive layer disposed at the diaphragm side. In driving the detector, a surface of the diaphragm is contacted with a surface of the structure temporarily by altering a voltage applied therebetween.
