消除拷贝全息图有害条纹的最优化角度

The Optimum Angle of Eliminating Harmful Fringes of Copy Holograms

分析了拷贝法制作全息图的有害条纹产生机理 ,提出采用适当入射角使各界面反射最小 ,从而消弱有害条纹的产生。本文用数值计算方法 (0 .618法 )求得该最优化入射角角度为 5 7.73°。

The generation principle of harmful fringe,when fabricating hologram in copying method,is analyses in the paper.It is proposed that the reflection from the interface can be kept to a minimum to avoid generating harmful fringe,while the incident angle is suitable.The optimum incidence which is 57.73° has been worked out by numeral calculating method,and the experiment results are given.
