用单波长激光制作真彩色全息图

研究将已有的彩色技术与彩色印刷术相结合,在无全色光致抗蚀剂的情况下,利用单一波长的激光光源和现有的蓝敏光致抗蚀剂,采用密度编码分区记录方法,在同一干版的不同区域记录三原色掩模的菲涅耳全息图,白光再现下,获得真彩色全息图.

Making Colour Hologram with Single-wavelength Laser

Combining the colour coding technology and colour printing,under the condition of anticorrosive cansed by non_panchromatic light,using the single_wavelength laser source and anticorrosive sensitive to blue light,the Fuller hologram masked by three primary colours is recorded in different areas of the same photographic plate by adopting the methods of density coding and partition recording.Under the daylight,the real colour hologram emerges.
