| 摘 要： | ＳＰＲＩＴＥ探测器是一种三引极ｎ型的ＨｇＣｄＴｅ光电导探测器，具有焦平面上的时间延迟积分（ＴＤＩ）功能，用于串扫和串并扫热成像系统。用建立在线性滤波理论基础上的调制传递函数（ＭＴＦ）评价、测试ＳＰＲＩＴＥ探测器的空间分辨能力，已有不少研究论文报道，但都忽略了测试用光学投影系系统对探测器ＭＴＦ测试的影响。除了光学镜头的传递特性外，光学投影系统中所特有的扫描部件的运动效应也较大程度上影响着探测器ＭＴＦ

| Abstract: | SPRITE detector, with the function of time delay integration(TDI), are utilized in serialscan and/or parallel-scan thermal imaging systems. In the MTF measurement of SPRITE detectors,the accuracy is degraded by the randomness and nonlineality of the scanning. Based on the discussion of this effect, a new MTF measurement method was presented. |
