非激光在怀特池中的传播特性

A White cell under the condition of non-laser

为了探索怀特池在不同特性光源条件下的性能,在使用虚拟仪器技术对怀特池反射光程进行仿真的基础上,研究了提高反射次数的一般规律和方法,同时特别研究了具有一定发散角的光束在怀特池中反射的模型,提出了光束直径及发散角与反射次数之间的关系,该关系可用于指导非激光光源的怀特池应用。仿真结果证明,光束直径和发散角越小,可达到的最高反射次数越多,实验也证明了这一点。

In order to study the performance of the White cell under the conditions of different characteristics of the light source, based on the simulation of White cell reflection optical path using the virtual instrument technology, the general rules and methods of improving the number of reflections are explored; meanwhile, a special study is carried out on the reflection model of beams with a certain divergence angle in the White cell, and the relationship between beam diameter as well as divergence angle and the number of reflection times is also proposed, which can be used to guide the White cell application of non-laser light source. Simulation results show that the smaller the beam diameter and divergence angle is, the more the reflection times, which is also confirmed by the experiment results.
