| 摘 要： | 目前拍摄模压全息母版用的记录材料都是光刻胶.本文从它本身的特点(灵敏度低,浮雕型相位光栅和拍摄对象是散射物体等)出发,指出要拍摄出质量好的光刻胶母版应当注意到的问题.诸如拍摄参数的选择应同时考虑到衍射效率和信噪比、照明的均匀性问题、逆共轭光再现、消偏振、相干长度、外界振动对拍摄的影响问题.通过分析表明高质量的全息图不可能靠延长曝光时间来获得,使用相干性好的大功率激光束来拍摄,是非常有必要的.

| Abstract: | The photoresist is used as recording materials to take the master of embossing hologram According to the characteristic of the photoresist(low sensitiveness ,embossing phase grating scattered objects as objects of recording ,etc )this paper points out how take good quality photoresist master For example ,the choice of taking parameters with high diffraction efficiency and gain good quality hologram by delaying exposure time |
| |
| Keywords: | Low sensitiveness Inverse conjugate light The etching depth of grating Rectangular speckle Signal-to-noise ratio |
