| 摘 要： | 重铬酸盐明胶(DCG)是一种重要的全息记录材料,它有高的衍射率和低的噪声,其衍射率之高几乎可接近理论值。它的主要缺点是光敏性差,对波长大于540nm的尤基本上不感光,加入一些染料可使其感光区扩大到红光(633nm)。本文讨论了用亚甲基兰敏化重铬酸盐明胶扩大到红光区的方法,用He—Ne激光得到衍射率为80%的全息图。

| Abstract: | Dichromated gelatin ( DCG ) is one of the best holographic recording materials because of its high diffraction efficiency and low noise nearly the uppermost theoretically possible diffraction efficiency. A major shortcoming of this material is that it is essentially in sensitive to light of wavelengths much longer than 540 nm. The spectral sensitivity of DCG can be extended to red light wavelengths by adding suitable dyes such as methylene blue. The sensitivity of dye-sensitized DCG exposed at 633nm.
In this paper we present the optimum niathed of DCG having its spectral sensitivity extended by methylane blue with a He-Ne laser and obtained diffraction efficiency of 80%. |
