像管在特定运动状态下动态传递函数的理论分析

THEORETIC ANALYSES FOR DYNAMIC TRANSFER FUNCTION OF IMAGE TUBE

在前人工作的基础上，利用傅立叶变换理论，在点扩展函数的空域因子和时域因子可分离的条件下，给出了像管动态传递函数的定性关系式。并针对一维坐标下二代像管在特定运动状态下的传递函数进行了具体的推导分析和理论计算，给出了具体的解析表达式及计算曲线。

In this paper we present a formula of the dynamic transfer function (DTF) of image tubes by means of Fourier transform for those cases where the spatial and temporal factors of point spread function are separable. Moreover, we give analytic results and curves of DTF for the image tube of second generation when objects move in specific ways.
