摘　　要：红外探测系统通常需要将探测器密集排列以增加它们的空间分辨率。在焦平面阵列中,当投射到某一特定探测器光敏面上的红外光子在另一个探测器中产生信号时,这种现象称为串音。串音可能会影响焦平面阵列的分辨率性能。在高性能光伏阵列中,串音的主要成分是光生载流子在焦平面阵列的相邻探测器之间的横向扩散。从基本概念入手,介绍了相关串音研究的发展情况以及对串音问题的理解和体会。Infrared detection systems usually need close-packed detectors in order to increase their spatial resolution.The crosstalk between individual elements in a focal plane array （FPA） occurs when the infrared photons incident on a particular detector＇s active area in the array generate signals in another detector. The resolution performance of a FPA may be limited by the crosstalk. The dominant form of the crosstalk occurring in a high performance photovoltaic array is associated with the photogenerated carriers diffusing laterally between adjacent elements within the FPA. Starting from basic concepts, the research progress and the understanding and comprehension of crosstalk are presented.
