摘要
光场中的衍射反比律和空间相干性反比律以及时间相干性反比律,併称为波动光学三个反比律,本文分别论述了这三个反比律的内涵和理论价值,及其新近应用;最后,本文将波动光学中的三个反比律与量子物理中的不确定性关系,作了类比和联通,旨在说明量子世界的不确定性关系,正是量子波动性的必然体现.
In a light field,the inverse law of diffraction,the inverse law of spatial coheerence as well as the inverse law of temporal coherence,they are named the three inverse laws of wave optics.This paper expounds the connotation and theoretical value of these three inverse laws respectively and their recent applications.Finally,this paper makes an analogy and connection between the inverse law of wave optics and the uncertainty relation of quantum phycics,aiming to illustrate that the uncertainty relation in the quantum world,is just the necessarily reflect of quantum wave property.
