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。
It is pointed out that the process of photographing the volumetric hologram and the pretreatment of the dry plate with the aqueous solution of triethanolamine change the thickness of the latex after exposure and corresponding chemical treatment and thus change the wavelength of the volumetric grating so that the color of the reproduced holographic image Change. Also reported is the experimental relationship between the concentration of triethanolamine in aqueous solution and the reproduction of the holographic image, the method of making different or multiple color holographic patterns on the same dry plate, and how to compensate for the reproduced images due to the different latex contractions in different color portions of the dried plate Difference in diffraction efficiency.
