摘要
资源遥感对红外探测器有较高的要求,如高探测率、高可靠性、低功耗、多谱段、探测率均匀性好、探测器元间串音小、可在较高温度下工作等。从工程应用的角度出发,将滤光片、红外探测器和前置放大器视为一个组件,考虑三者间的相互影响,对组件的主要性能指标和评测方法进行了论述,提出了探测器组件设计和测试时需要注意的问题。在实际工作中,根据系统要求,正确理解性能参数的含义,从应用的角度提出合理的测试评价方法,对推动红外探测器的应用具有重要意义。
The high demand is applied to the infrared detectors for resources remote sensing,such as high detectivity, high reliability, low power, multi-waveband, good uniformity of detectivity. The assembly usually consists of filters, infrared detectors and pre -amplifiers. The main parameters of the assembly for remote sensing applications are discussed in this paper. Some problems are thought over in the assembly designing and testing. In detector applications, it is very important that specific meaning of assembly parameters and reasonable testing methods are very important.
