摘　　要：受红外探测器广泛应用的影响,对红外探测器性能数据分析的需求呈多样性和复杂性。针对部分不可直接测得或者获取难度大的特性参数(如暗电流、量子效率等),提出了一种基于QT的红外探测器特性参数集成测试方法,包括传统测试系统以及自主开发的计算软件。计算软件使用QT及C++语言开发。独立自主完成底层算法设计开发,使其具备全波段任意温度黑体辐射光子数、暗电流、量子效率等多种特性参数计算功能。现有计算软件仅支持单一性能参数计算功能,且参数计算过程中存在普适性差、容错性低等问题。所提出的软件对底层计算原理采取封包处理,综合了多个性能参数计算功能。经多种阵列尺寸红外探测器验证,该软件具有准确、便捷等优点。Affected by the widespread application of infrared detectors,the demand for performance data analysis of infrared detectors is diverse and complex.For some characteristic parameters that cannot be directly measured or are difficult to obtain(such as dark current,quantum efficiency,etc.),a QT-based integrated test method for infrared detector characteristic parameters is proposed,including traditional test systems and self-developed calculation software.The calculation software is developed using QT and C++language.The underlying algorithm design and development is completed independently,so that it has the calculation function of various characteristic parameters such as the number of blackbody radiation photons,dark current,quantum efficiency,etc.at any temperature in the full band.The existing calculation software only supports a single performance parameter calculation function,and there are problems such as poor universality and low fault tolerance in the parameter calculation process.The proposed software adopts packet processing for the underlying calculation principle and integrates multiple performance parameter calculation functions.After verification by infrared detectors of various array sizes,the software has the advantages of accuracy and convenience.
