Abstract

Dichromated poly(acrylic acid) films with dimethyl formamide have been used as a real-time recording medium for volume transmission holograms. In this study a simple computer-generated holographic grating with a sinusoidal amplitude profile is copied onto this recording material by the contact-copying technique. The experimental setup for the contact copying of a computer-generated hologram (CGH) is explained, and the phase modulation is observed for a different exposure time. Theoretical and experimental diffraction efficiency values for the CGH copy are also evaluated. Photographs of the original and copy of the CGH on the photopolymer film are presented.

摘要

重铬酸盐化的聚丙烯酸薄膜与二甲基甲酰胺已被用作体积透射全息图的实时记录介质。在本研究中，通过接触复制技术将具有正弦振幅分布的简单计算机生成全息光栅复制到这种记录材料上。解释了用于计算机生成全息图（CGH）接触复制的实验装置，并观察了不同曝光时间下的相位调制。还评估了CGH副本的理论和实验衍射效率值。展示了光聚合物薄膜上CGH原件和副本的照片。
