This paper deals with the generalization of the third order aberrations of magnetic deflection to the situation when the electron beam is originally immersed in a magnetic field. The formulae of third order magnetic deflection aberration coefficients in an arbitrary plane have been derived. The formulae are simplified and hence easy for calculation. These aberration coefficients have been applied to analyse the raster patterns produced by the in-line guns.

A new method of preparing the raster plate with optical fiber has been developed. The parameters and measurement result of the element of raster plate show that a total of micro-lenticular elements is 2.25?104. The pitch is 0.4mm. The photographic resolving power of the optical fiber raster plate for a single lenticular element is 110 line-pair mm-1, the focal length 0.3mm. The raster plate has total information capacity of 1.089 ?107 bit.

This paper describes and analyses the imaging performance of high speed raster photography with two dimensional pulse functional array. The lenticular plate has been used in the optical system to get the point-array-image of the raster plate which corresponds to the object. The density distribution of the point-array-image was measured. The resolution of the raster image is relative to the pitch of the raster plate. The high speed raster photography can obtain the higher relative brightness and lower resolution of image as compared with the conventional high speed photography. The frame interval is equal to the size of the image point. For conventional high speed photography, a frame interval must be larger than the height of frame. So that raster photography can reach high framing rate. By reducing the frame size of the raster image, one can increase the resolution of the image.

本文叙述了网格高速摄影的成象特性,用二维脉冲序列函数进行了分析.把网格器件用于光学系统中,获得了图象点阵列照片.目标和阵列象是对应的.测量了底片上的图象点阵列的密度分布,指出了分辨率和网格节距的关系.网格高速摄影与普通高速摄影相比是降低了图象分辨率而提高了图象对比亮度.在光学系统中使用网格器件的作用是把一个具有连续轮廓的外界目标分割成网格点阵象,通过点阵象作相对移动,在同一张底片上就可以得到许多与目标相对应的图象,网格高速摄影就是利用这种点阵运动原理来实现的.
