Meridian Line Spread Function Algorithm of Electrostatic Image Tube Electron Optics System

GUO Jian;DING Sheng;Department of Technical Support Engineering, Academy of Armored Force Engineering;Department of Control Engineering, Academy of Armored Force Engineering;  
There are a lot of methods to evaluate image quality of image tube,in which calculating the modulation transfer function of the image tube is a very important way.Aiming at the defect of the meridian spread function of electrostatic image tube electron optical system and the influence which brings to the meridian modulation transfer function. this paper improves the calculation program of the mermiran spread function by programming language Borland C++6.0,and lists the comparison between the original program and the modified one of the xx1380 second generation shimmer tube. Through comparison we can clearly find the modified program is much better for the meridian line spread function of electrostatic image tube electron optics system, and a better simulation result can be got. It has a positive effect to image evaluation and imaging tube design.
