| 摘 要： | 本文提出了测量自聚焦棒透镜周期长度的一种新方法。通过自聚焦透镜后光斑的大小与周期长度之间的确定关系,测定光斑直径而求得周期长度的值。实验分别对锂玻璃和铊玻璃自聚焦透镜进行测量,获得了满意的结果。

Periodic Length of Selfoc Lens Measuring by Spot Method |
| |
| Abstract: | A new method used for measuring the periodic length of Solfoc lens is pr esented. When a parral light beam traverses the selfoc lens, the spot size of the light beam and the perioder length of the selfoc lens have a fix relation. We can find periodic length of the selfoc from measuring dia meter of The spot. The selfoc lens miking from Li gless and Tl glass were measuring separately, and the results are satisfactory. |
