红敏明胶波导全息图(WGH)

Wave—Guided Holograms with Red—Sensitive Dichromate Gelatin

用红敏明胶拍摄波导全息图，并用CCD测量了材料的信噪比，采用这种红敏明胶拍摄的波导全息图，能有效地提高波导全息图的象质，为波导全息图的实际应用提供了可能。

In this paper, we record a WGH with n new kind of red sensitive dichromate gelatin produced in our lab. With it, we overcome many difficulties in recording WGH and largely improve the quality of the WGH. We also measure the ratio (s/n)of the recording materiel. The results of the experiment show that by using this kind of red sensitive dichromate gelatin we can present a possibility of the practical use of the WGH in the areas in holographic display and HOE.
