摘要
焦距是透镜最重要的光学参数 ,应用泰伯—莫尔法测量长焦距透镜焦距具有重要的实践价值。本文介绍了泰伯—莫尔法的原理 ,详细分析了各种实验方法 ,进行分类比较 ,并提出了改进措施。
Focal length is the important optical parameter of o ptical lens. It is valuable that methods based on Talbot effect and Moire technique are applied fo r measuring the long focal of lens. In this paper the principle of Talbot effec t and Moire technique is introduced, various experimental methods are analyzed, c lassified and compared in detail. Finally, improvement is presented.
