| 摘 要： | 对于下一代光盘系统而言，GaN激光器和高数值孔径（NA）的物镜是关键组件。本文介绍了几种HD-DVD光学系统物镜的设计方案，并对其进行比较研究，发现要根据不同的要求来设计物镜，对像差要求高的要采用两元件型或者三元件型物镜；而对于要求结构简单、装配容易、工作距离大的光学头，要采用单元型物镜。在解决其与CD和DVD的兼容性问题时，可采用物镜前插入补偿装置来控制物镜的数值孔径。

| Abstract: | In the next generation of optical disk system,GaN laser and high numerical aperture(NA)objective lens are two key components.This paper describes some design ways of objective lens for HD-DVD optical system,and through comparison we find that we should design objective lens according to different requirements.For diminishing aberration we should apply two -element objective lens,and for compact design,easy assembly and wide working distance we should apply single -element objective lens.When solving the compatibility with CD and DVD,we set a compensator before the objective lens to control NA of it. |
