OSLO中的样板数据分析是个鸡肋，功能简单不实用，OSLO的最大缺点是为用户考虑的太少，尽管它的灵活性可以让我为所欲为。当镜头面数很多时，套样板的方法显得至关重要，程序提供自动套样板功能，其结果也许并非最佳结果，但也能相当程度地反应样板套取方法的优劣趋势，设计人员可以在此基础上根据自己的理论知识和经验作进一步的改善优化，鉴于此，用CCL将Zemax的样板套取功能完全复现，除实现了Zemax中的4种算法，还添加了额外3种算法。 IO*l vy
程序的难点有：1、对样板文件的处理，难处是用CCL提供的有限的文件处理命令和就那么几个文本操作函数实现起来，有很多东西要自己代码实现，这里的样板文件格式与Zemax的全同，Zemax的现成样板文件必须拿过来就能用；2、对OSLO中的系统数据的操作，诸如变量的保存、中间优化结果的存储、套样板后数据如何恢复等等，这里涉及的问题，OSLO提供的内部命令及变量都能解决；3、算法问题，也就是该如何套，可以参考Zemax现成的几种算法，<<Modern lens desgin>>一书中提到的算法也尽量实现；4、其他细节问题，如样板半径如何算是符合套样标准（可以参考Zemax的），对文本行的解析得到样板数据等等 T!1SMo^

结果一般是Fit_MF_BigToSmall和Fit_WorstToBest方法较好，Fit_MF_BigToSmall算是很BT的方法，其次是ShortToLong和Power_BitToSmall，我比较看重看依据像差来套的方法，但其结果最好时的情况不多，因为这个方法主观因素比较严重，很难用程序去精确实现，这是手动套样板的方法首选。
