【摘要】 本文巧妙地运用了全息图的光路可逆性,采用两面反射镜与小面积全息图相结合,制得了视场角接近180°的大视角彩虹全息图.整个过程分两步完成,无需任何特殊的光学元件.文中给出了实验结果,并进行了讨论.更多还原

【Abstract】 By using the opbioal path reversibility of hologram, we have made the large-viewing-angle rainbow holograms by means of two reflection mirrors. The viewing angle of the hologram is close to 180°. The process includes two steps, and does not need any special or expensive optical element. The experimental result is presented and analysed.更多还原
