四机部1431所研制的SF-2002型热电摄象管已通过鉴定,它对8～14微米波段的热辐射有良好的响应,改变窗口的镀膜厚度或窗口材料还可把响应波段的下限扩展到2微米左右。它在探寻电力线路故障、查找火源以及在石油、化工、冶金等方面用途广泛。对于红外波段的激光,也可应用本热电摄象管作检测手段。安徽光机所在激光大气传输试验中,成功地用这种摄象管配上普通的工业电视观测了CO_2激光的模式和经过大气扰动后的图
The SF-2002 pyroelectric tube developed by the four-machine unit 1431 has passed the certification. It has a good response to the heat radiation in the 8-14 micron wavelength band. Changing the window coating thickness or the window material can also extend the lower limit of the response band To 2 microns or so. It is in the search for power line failure, find the source of fire and a wide range of applications in the petroleum, chemical, metallurgical and other fields. For the infrared band laser, the thermistor can also be used as a detection means. Anhui light machine where the laser atmospheric transmission test, the successful use of this camera coupled with ordinary industrial television observed CO_2 laser mode and after the disturbance of the air map
