全息拍摄中二元光学元件的应用
Application of binary optics element (BOE) in the process of hologram

摘要: 物光和参考光的均匀性,对彩虹全息的拍摄,特别是模压全息防伪标记母版的拍摄都具有重要意义。为了获得均匀的物光和参考光,应用二元光学元件,通过光学变换来实现。采用二步综合法拍摄的实验表明,参考光和物光的均匀性都得到改善,各个标记的衍射效率也较为接近。Abstract: Both object wave and reference wave should be uniform in rainbow holograph,especially in mould pressing hologram master plate of prevent falsifier label.Binary optical element(BOE) can be used to obtain the uniform wave and BOE may be made by using of spatial light modulator in laboratory condition.
