利用衍射光原理开发研制沟槽形状测试仪

The exploration and development of testing equipment for the structure of groove by the diffraction principle

绪论 光盘基板采用注塑成型方法来制造。注塑成型条件 决定基板沟槽的形状,因此生产管理方面是一项很重要 的管理项目。而且,验收光盘母盘时沟槽是否达到规格, 需要进行测试检验。这次开发成功的沟槽评价装置具有 使用方便,操作简单,实用性强等特点。并且,在光盘 制造所有工程上都可以使用此装置。在此作详细报告。

The substrates of the optical disks are manufactured by the injection compression molding. Its form is an important control item in production control of the substrate because it depends on a plastic condition strongly. Moreover, a groove form of the stumper is conformable to the specifications, you must examine reception. So, details are reported because the groove profiler which could be used easily by the optical disk manufacture process all was developed and it succeeded in merchandising.
