彩色全息图的研究

通过使用Ronchi光栅和滤波片 ,把一张彩色透明片的红、绿、蓝信息编码记录在一张黑白胶片上并用单色激光制作彩色全息图。采用彩虹全息术 ,获得记录于同一块干版上的原彩色图由红、绿、蓝三色所成的三个基色彩虹全息象 ,用白光透射再现 ,得到原彩色图的真彩色全息象。

Researches on the Colour Holograms

This paper discusses the method of coding the three_basic_colour image of the colour transparent film with a Ronchi grating and optical filter,recording it on a white_black film,and making a colour hologram with monochromatic laser. The three_basic_colour rainbow holograms of the primary colour image,which are recorded on the same photographic plate and made up of green, red and blue,can be obtained by adopting the rainbow hologram. Reconstructed by the transmission of white light, a real colour hologram of the primary one is obtained.
