The real-time storage is obtained in the organic dye BDN solution in toluene by doublet degenerate four wave mixing induced thermal refractive index grating.

本文利用二重简并四波混频感生折射率光栅，实现了光信息在有机染料BDN溶液中的实时存储。

Then calculated the original results of the doublet lenses in the muzzle-axis obtain optical system by Wave-deviation Method, designed and optimized this system by ZEMAX.

本文首先完成了对波差法光学设计理论的探讨，并进行了实例讲解。
