摘　　要：提出了一种评价双色探测器的相对光谱串音的模型及测试方法。为验证模型及测试方法的可行性,采用分子束外延锗基叠层异质结构碲镉汞薄膜材料,研制了微台面结构短波/中波双色红外焦平面探测器原理器件,进行了相对光谱串音测试,归纳出3种主要的相对光谱串音模式,并结合材料、器件结构和工艺特点,分析了相对光谱串音的成因。The article reports a model of the relative spectral response for evaluating the crosstalk between different bands in dual-band detectors. To verify the model, the test of the crosstalk between different bands by the relative spectral response has been carried out. The SW/MW dual-band IRFPA detectors which fabricated by MBE triple layer heterogeneous structure MCT/Ge were used for validating the effect of model, and three main crosstalk modes and the reason which caused crosstalk between the different bands in same pixel were concluded.
