热电测辐射热器是红外辐射热探测器的一个新发展。在热探测器中,入射辐射改变了测辐射热器元件的温度,然后又由从属温度依赖特性探测该温度变化。热电探测器中所用的从属特性就是大的自发电极化变化,在温度改变时有些材料中就会发生这种变化。这种材料是热电性的,并包括所有铁电 Thermoelectric radiant heat detector is a new development of infrared radiation heat detector. In the heat detector, the incident radiation changes the temperature of the bolometer element, which in turn is detected by the dependent temperature dependent characteristic. The dependent property used in the pyroelectric detector is a large spontaneous polarization change that occurs in some materials as the temperature changes. This material is pyroelectric and includes all ferroelectric
