中文摘要	红外焦平面探测器的测试系统在国内少之甚少，而天文红外焦平面的测试系统几乎还是空白，目前在国外也只有几家的测试系统比较成熟，如法国的HGH公司的测试产品，但是价格非常昂贵。本文主要是通过对其测试原理的深入研究，在其基础上，设计和搭建适合天文红外焦平面探测器的测试系系统。由于天文红外探测器有着比其他领域红外探测器更高的性能要求，主要表现在对微弱的天文辐射需有极高的灵敏度；探测器本身需具有极小的本底噪声和暗电流。对红外焦平面性能参数的测试评估是红外探测器发展中的关键技术之一。通过对探测器测试评估，可以实现三个目标。第一，可以评估探测器是否能达到天文观测目标所需要的精度；第二，根据天文观测的特殊需求对探测器进行改装；第三，可以对红外探测器的一些参数进行及时标定和修正。本论文选题天文红外焦平面探测器性能参数的测试和评估方法研究，第一章和第二章阐述了解国内外天文红外焦平面的进展、天文红外焦平面探测器的工作原理、以及红外天文观测所关注的性能参数及其表示方法；第三章归纳和总结天文红外观测的主要性能参数的定义及其测试方法；第四章讲述红外焦平面探测器测试平台的搭建；第五章讲述不同波段的红外探测器测试结果和分析；第六章对全文做了总结以及对未来工作的展望。
英文摘要	The testing system of Infrared focal plane detector in the domestic is very little, and the astronomical infrared focal plane testing system is almost blank. Today, they are only several testing systems is more mature in the abroad, such as the testing products of the France HGH company, but the price is very expensive. This article mainly through the in-depth study of its testing principle, on the basis of its testing principle, we designed and built the testing system which is suitable for tasting astronomical infrared focal plane detector.Because of that the astronomical infrared detector has higher requirements about the performances than the ordinary infrared detector, they mainly displays of needing high sensitivity about the faint astronomical radiation; having minimal local noise and dark current.Evaluating and testing on the performance parameters of infrared focal plane is one of the key technologies in the development of infrared detector. We can realize three goals Through testing and evaluating of the detector, First is that, we could assess whether the detector could catcher the required accuracy about astronomical observations .Second, according to the specific requirements of the astronomical observations ，we could modify the ordinary detector and lead it could be used for astronomical. Third, we could calibrate and correct some parameters of the infrared detector in a timely manner. This paper analyzes them in detail by the following six chapters. Chapter 1 and chapter 2 by investigating and researching, we could understand the development of astronomical infrared focal plane at home and abroad, find the working principle of astronomical infrared focal plane detector, also the important parameters of infrared astronomical observation; The third chapter about inducting and summering the definition and test method of the main performance parameters; Fourth and fifth chapter two mainly builds infrared focal plane detector test platform, and made the testing and analyzing of results about the infrared detectors respecting in different wavelengths; Chapter 6 summarizing of the full text and make a outlook for the future work.
