在Excel中用VBA实现透镜设计软件的开发

Main Lens Curvature Design Soft Ware for Thomson Simulation Lens Set of Color Picture Tube

本文首先介绍着屏的归一化处理。接着提出主透镜的曲面模型,并分析获取该曲面的条件。然后以纠正着屏偏差为目标论述如何在旧透镜的基础上获得了新的透镜曲面。扼要介绍了软件的组成和一些算法。通过实例验证本文的方法,阐述这种软件的现实意义。

A dedicated soft ware has been successfully developed to optimize the curvature of the main lens used in Thomson simulation lens-set of color picture tube （CPT）design. The optimized main lens curvature was obtained by correcting the register aberration of the conventional lens. The soft ware architecture and algorithms were discussed also. The design method and the soft ware were repeatedly tested in realistic cases with satisfactory results.
