| 摘 要： | 受振动的影响,在积分时间内,光学系统成像是一个动态过程.对于动态成像,常采用动态调制传递函数(MTF)作为评价振动对像质影响的工具.针对动态MTF,提出一种适用于任意运动形式的数值计算方法,该方法还可以扩展到计算二维运动时的动态MTF.该方法可用于预估和评价动态成像系统的成像质量,计算的结果还可用于运动模糊图像的仿真与...

| Abstract: | Influenced by vibration,the imaging of optical system is a dynamic process during the integration time.As to dynamic imaging,the dynamic modulation transfer function(MTF) is usually used as a tool to evaluate image quality.A numerical method is put forward to calculate the dynamic MTF and it is applicable in principle to any type of vibration and can be expanded to two-dimensional motion.This method can be applied for predicting and evaluating image quality of dynamic imaging systems and the results can als... |
