A bleach process is described which gives high-efficiency, low-noise holograms. Potassium ferricyanide is used as the bleaching agent. The main differences between this process and earlier uses of potassium ferricyanide for bleaching are a different developer and a special drying procedure. The following values for the efficiency were obtained: 45% for a plane grating, 25% for a hologram of a diffuse subject, and between 10% and 15% for holograms of data masks. The bleached holograms are stable in an ordinary laboratory atmosphere but degrade in very high humidity.
描述了一种能产生高效、低噪声全息图的漂白工艺。使用铁氰化钾作为漂白剂。该工艺与早期使用铁氰化钾进行漂白的主要区别在于显影剂不同以及采用了特殊的干燥程序。获得了以下效率值：平面光栅为45%，漫射物体全息图为25%，数据掩膜全息图为10%至15%。漂白后的全息图在普通实验室环境中是稳定的，但在湿度非常高的情况下会降解。
