一般说长波红外探测器的发展落后于长波红外光源的发展。特别是在8～14微米大气窗,极好的激光产生后,合适的探测器的设计并未跟上。例如,最近发展的二氧化碳波导激光,在激光发射机的尺寸、轻便性和可能的应用方面都是引人注目的突破。这样的二氧化碳激光已经使人们看出它在激光雷达、数据通讯、污染探测、红外前视系统和工业等方面的应用正在增长。为激光的应用,典型的探测器有锗掺铜、锗掺汞和热电。锗掺杂探测器在实验室内论证系统的设计是有用的,但是不能推荐给野 In general, the development of longwave infrared detectors lags behind the development of long-wave infrared light sources. Especially in the 8 ~ 14 micron window, the proper detector design did not keep up with the excellent laser generation. For example, the recent development of CO2 waveguide lasers is a compelling breakthrough in the size, portability and potential applications of laser transmitters. Such carbon dioxide lasers have led to an increase in its use in laser radar, data communications, pollution detection, infrared foresight systems and industrial applications. For laser applications, typical detectors are doped with germanium, germanium doped with mercury, and thermoelectric. Ge doped detectors prove the design of the system in the laboratory is useful, but can not recommend to the wild
