本专利所描述的热电探测器,由有效探测器和补偿探测器组成。探测器材料相同。它们夹在两层电极之间,其中一层电极是公共的。两个探测器极化相反,并联相接,就可补偿环境温度变化。热电探测器的问题之一是其灵敏度随环境温度而变化。温度一变,探测器上的电荷 The pyroelectric detector described in this patent consists of an effective detector and a compensation detector. The same detector material. They are sandwiched between two electrodes, one of which is common to the electrodes. On the contrary, the polarizations of two detectors are connected in parallel to compensate for the change of ambient temperature. One of the problems with a pyroelectric detector is that its sensitivity varies with the ambient temperature. A temperature change, the detector charge
