The calculation methods of the modulation transfer function (MTF) infrared (IR) focal plane arrays (FPAs) on the base of photodiodes are presented. The obtained results are based on the preliminary calculations of the areal distribution of quantum efficiency by modeling the 3-D diffusion process of photogenerated charge carriers in the photosensitive layer of IR FPA by the Monte Carlo method. The analysis of MTF is carried out for 1-D test patterns and 2-D “chess-type” test patterns, taking into account the basic photoelectric and design parameters of photosensitive elements.

调制传递函数对 HgCdTe 红外 FPA 材料和设计参数的依赖性


提出了基于光电二极管的调制传递函数（MTF）红外（IR）焦平面阵列（FPA）的计算方法。所获得的结果基于通过蒙特卡罗方法对红外焦平面阵列光敏层中光生载流子的3维扩散过程进行建模，对量子效率的面积分布进行了初步计算。 MTF分析针对一维测试图案和二维“国际象棋型”测试图案进行，考虑到基本光电和感光元件的设计参数。
