Abstract

Irradiation of a cooled matrix photodetector by parasitic radiation in a cryostat for different shapes and designs of a cold diaphragm is numerically simulated. It is found that the optimal shape of a cold diaphragm is a cylinder with two internal optics diaphragms (additional diaphragms). Irradiation of the matrix photodetector by parasitic radiation is about \(9{.}82\times 10^{-5}\) W \(\cdot\) cm\({}^{-2}\) with an uneven distribution over the area of about 3\(\%\).

红外热像仪冷却膜片优化设计模拟

摘要数值模拟了不同形状和设计的冷隔膜在低温恒温器中对冷却矩阵光电探测器的寄生辐射。结果发现，冷隔膜的最佳形状是带有两个内部光学隔膜（附加隔膜）的圆柱体。寄生辐射对矩阵光电探测器的辐照约为\(9{.}82\times 10^{-5}\) W\(\cdot\) cm\({}^{-2}\) ，在约3\(\%)的面积上分布不均。
