利用彩色打印机技术制作多位相彩虹全息色编码器

Multi phase Color encoder for Rainbow Holography Making Using Color printer Technology

提出一种新的集分束／整形于一体的彩虹全息色编码器，该编码器可获得较高的衍射效率和很好的光场均匀性。同时，采用一种集追迹法、Ｇ－Ｓ算法、Ｙ－Ｇ算法为一体的综合迭代算法进行该器件的设计，计算机模拟结果显示其非均匀性小于０．０１％，衍射效率为９３．３％。

A novel color encoder which has dual function of a beamsplitter and a beamshaper is proposed. This encoder could acquire higher diffraction efficiency and very good uniformity of light field with high diffraction efficiency. An algorithm combining tracing algorithm, G S algorithm and Y G algorithm is used to design this encoder. The result by computer simulation shows: the diffraction efficiency is up to 93.3%, and the non uniformity is less than 0.01%. And a new approach to encode and make a phase element by using color printer techniques is also proposed.
