随机运动赝热光等概率假设 Random movement Pseudothermal source Assumption of equal probability

摘要

借鉴热力学统计物理描述热随机运动的方法,提出了一种新的方法来描述毛玻璃粗糙表面引起的光场光强的随机分布。我们提出了相应的等概率假设,根据这条基本假设,推导出了光场中光斑的光强分布。进一步我们设计了三个实验,来验证模型的正确性。实验结果和我们的假设及模型符合得很好。本文的方法可推广到其他随机运动的描述。

Abstract

According to the method of statistical physics, a new method was put forward to describe the chaotic character of pseudothermal source. On the basis of the assumption, of equal probabilities we introduced we deduced the intensity distribution of the facula. Moreover, we designed three experiments to prove the model. The experimental results fit the assumption and the model well. This method could be generalized to describe the other random movement.
