摘　　要：对于在低温背景条件下应用的红外焦平面探测器,在其设计阶段首先需要确认的是探测器在低温背景下的主要性能参数是否满足应用需求。通过单元探测器的基本理论公式,从性能测试的角度,推导出了焦平面探测器主要性能指标的理论计算公式,包括峰值响应率、噪声、峰值探测率、动态范围等。提出了红外焦平面探测器主要性能参数计算的设计流程,并通过实例对长波红外焦平面探测器在低温背景下的性能参数进行了计算、设计及验证,实测结果与理论计算符合较好。表明了理论公式及设计流程具有较好的实用性,可为红外焦平面探测器的应用设计提供参考。For infrared FPA detectors applied to a low-temperature background,the first aspect that must be confirmed in the design stage is whether the performance of the detectors at low temperatures meets the application requirements.Using the basic theoretical formula of the unit detector,from the perspective of testing,the main performance parameters of the theoretical calculation formula for FPA detectors were deduced,including the peak responsivity,noise,peak detectivity,and dynamic range.In addition,flowchart of the calculation design for the detectors was proposed.The main parameters of the long-wave infrared FPA detector at low temperatures were designed,calculated,and verified using an example,and the results are in good agreement with the theoretical calculations.Thus,the theoretical formula and design calculation flow are practical and can provide a reference for designing infrared FPA detectors.
