Hadni等人(1965年)首先建议电视摄象管可以使用热电材料。Le Carvennec(1969年)采纳了这个建议,并采用在居里温度附近温度灵敏的介质作为材料,但由于制造在居里温度附近有均匀极化的大晶体薄片有困难,因此器件的工作不令人满意。在这以后,法国和英国很重视以电荷探测方式工作的热电摄象管。这种方式在第二节的第二小节中已进行了讨论,它的原理是靶温度的变化ΔT引起自发极化变化ΔP_s继而ΔP_s在靶的两端产生一个电压变
Hadni et al. (1965) first proposed the use of thermoelectric materials for television cameras. Le Carvennec (1969) adopted this proposal and uses a temperature-sensitive medium near the Curie temperature as a material, but due to the difficulty of manufacturing large crystalline flakes with uniform polarization around the Curie temperature, the device does not work People are satisfied. Since then, France and the United Kingdom have placed great emphasis on the use of charge-probe thermoelectric video tubes. This approach has been discussed in the second subsection of Section II, which is based on the principle that a change in target temperature ΔT causes a spontaneous polarization change ΔP_s which in turn causes a voltage change across ΔP_s at the target
