一、前言最近,磁聚焦、静电偏转(MS)型摄像管因其具有分辨率高且一致性好、图像畸变小等特点而被越来越多地用于业务和广播电视摄像机。另外,SS型摄像管的实用化正在进行中,可期待出现业务和生活用的小型、轻量、省电的视频摄像机。静电偏转摄像管的特征是在管内形成锯齿状图案电极。我们以前曾用拉普拉斯方程的分离变量法求解曲线箭形图案的三维偏转电场,对MS型摄像管的聚焦、偏
I. INTRODUCTION Recently, MS magnetic focusing and electrostatic deflection (MS) -based video cameras have been increasingly used in business and broadcast video cameras for their high resolution and consistency, and small image distortion. In addition, the practical application of the SS type video tube is underway, and small, lightweight and power saving video cameras for business and daily life are expected. Electrostatic deflection camera tubes feature jagged pattern electrodes formed inside the tube. We have previously used Laplace’s discrete variable method to solve the three-dimensional deflection electric field of a curved arrow pattern, focusing on the MS tube,
