白光再现多色体积全息图的研制

指出用体积全息制作工艺图片的拍摄方法和用三乙醇胺水溶液预处理干版,在曝光和相应的化学处理后,乳胶的厚度被改变,因而也改变了体积光栅的波长,使再现全息像的颜色发生变化。还报道了三乙醇胺水溶液的浓度与再现全息像颜色的实验关系,在同一干版上制作不同或多种颜色全息图案的方法;如何补偿由于干版不同颜色部分的乳胶收缩不同而造成的再现图像衍射效率的不同。

Study on multicolor volume hologram of white-light reconstraction

This paper presents the prospect,preparing metho d of the reflecting volume holographic pictures.Before the plate was explored,it was soaked in TEA solution.After explored and chemically processing,the emulsio n thickness was changed,so the wavelength of the volume grating and the color of the reconstructed image were changed,too. This paper indicates the relationship of the TEA concentration to color of the reconstructed image,the making method of multicolor hologram in a plate,and points out how to compensate the differenc es of the diffraction efficiency and color difference.
