摘　　要：针对国外进口长波4×288扫描型探测器,通过分析其光敏元在扫描过程中探测到的图像像素信号强度和相邻图像像素信号的混叠影响,给出了探测器光敏元尺寸与探测器焦平面上图像像素尺寸之间的相互关系,为新型扫描型探测器阵列光敏元尺寸设计、成像积分时间占空比设计提供了参考。According to the import LW 4×288 scanning detector,it analyzes the mix-overlap effects between the signal intensity and the signal of nearby imaging pixel.The imaging signal intensity is detected by the photosensitive pixels during the course of scanning.At last,the result shows the relationship between the photosensitive pixel size of scanning detector and the imaging pixel size on the FPA.For the new type scanning detector,it will be beneficial to the design of not only photosensitive pixel’s size but also the integration time’s duty cycle.
