通过化学处理获得多种颜色的反射全息图

Study on obtaining multicolor reflection volume hologram through chemical treatment

在拍摄体积反射全息时，若事先用三乙醇胺水溶液浸泡未曝光的干板，可以导致乳胶收缩，因而改变空间光栅的频率，使再现全息像的颜色发生变化。通过大量实验我们发现了，三乙醇胺水溶液的浓度与再现全息像颜色的关系。本文还报导了在同一干板上制作不同或多种颜色全息图像的方法。

While recording reflection volume hologram,if we let the plate soak in TEA solution before exposure,the emulsion contraction is caused,thus,the wavelength of space grating is changed,the color of image is changed,too.Through a lot of many experiments,we find the relationship between the concentration of TEA solution and the color of image.In this paper,we also report a method of making multicolor reflection volume hologram in a plate through chemical treatment.
