摘要
提出一种一步法拍摄大视角彩虹全息图的新方法。以多个准直透镜提供大孔径的参考光束,并使全息干板成一角度围住记录物体,记录大视角的主全息图。利用三个φ=180mm的准直透镜获得了视角为110°的彩虹全息图。
A kind of rainbow holography with large viewing angle is presented. Masterholography are recorded through several collimating lens to provide a reference light beam withlarge aperature. Then a large viewing angle rainbow holographm is recorded with these masterholograms. A rainbow hologram with 110~0 viewing angle has obtained by using three 180mmdiameter lens.
