显示反射全息图单光束相干复制技术

TECHNIQUE FOR REPLICATING DISPLAY REFLECTION HOLOGRAMS USING SINGLE LASER BEAM

描述用单光束激光复制银盐白光显示反射全息图的技术本技术的关键：１） 母全息图的颜色必须恢复到满足其布拉格条件；２） 复制所用的光波与记录母全息图时的参考波相同；３） 复制所用的激光采用平行偏振，以减少界面反射；４） 采用白糖溶液作为折射率匹配液。

Technique for replicating silver-halide white-light display reflection holograms using single laser beam is described.The key points of the technique are:1) the color of the master holograms must satisfy Bragg condition;2) the wavelength for replication must be the same as the one used for recording the master;3) the polarization direction of the laser beam for replication is better to be parallel to the incident plane,in order to reduce the reflection at the interface;4) using sugar solution as the index-matching fluid for the best effect.
