微型光学镜头性能检测及优化设计研究

Performance Measurement and Optimal Design for Micro Optical Lens

测试了两款环带镜头的光学性能，分析了测试系统中各组件对测试结果的影响，特别是CCD离散器件采样的影响。

We tested the two types of lenses and compared the results , analyzed the effects of the auxiliary equipment , especially the CCD discrete sampling period .

给出了加工检测结果以及镜头的主要性能指标。

The results of manufacture and test as well the lens performance are given .

深入地讨论了转接镜头的光学性能要求，并进行了光学设计。

This paper also discusses the requirement of optical performance for the transfer lens and designs the transfer lens .

实验结果表明，该方法在镜头边界检测性能上要优于已有的基于帧差的镜头边界检测方法，提取的关键帧对镜头的视觉内容具有较好的表达能力，且可在视频回放时实时执行。

Experimental results show that the performance of shot boundary detection is superior to the traditional frame difference-based methods , and the extracted key frames can well express the video contents .

所有的镜头都将在这个设计中获益，包括传统的那些。所以人们会发现联动测距镜头的性能也有提高。

All lenses will benefit from this , including legacy glass so people will see improved performance with their rangefinder lenses .
