本文对多路合成彩虹全息图接触式复制过程中如何提高复制全息图的成像质量进行了探讨。使用PFG-01胶片拍摄的基元全息图模拟合成彩虹全息图的母板,测量了母板基元全息图再现时由于散射和漫射引起的噪声。文中还对使用二甲苯及饱和蔗糖水溶液作为匹配液对衍射效率及漫射噪声的影响进行了讨论。
In this paper, how to improve the imaging quality of replicated hologram in multi-channel synthetic rainbow hologram contact-copying process is discussed. Primitive holograms taken with PFG-01 film were used to simulate the master of a rainbow hologram and the noise due to scattering and diffusion during the reproduction of the master hologram was measured. The effects of using xylene and saturated aqueous sucrose solution as a matching liquid on the diffraction efficiency and diffusion noise are also discussed.
