Abstract: In a light field，the inverse law of diffraction，the inverse law of spatial coheerence as well as the in

verse 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 quan

tum phycics，aiming to illustrate that the uncertainty relation in the quantum world，is just the necessarily reflect of

quantum wave property.

Key words: wavefront, diffraction, spatial coherence, temporal coherence, uncertainty relation, femtosecond
