摘要
针对彩虹全息图观察视角狭小等问题,基于全息记录、再现的多重性原理,对多重视角再现作了详细的理论分析,提出了一种多束参考光的一步大视角彩虹全息方法.该方法能实现再现像的多次色序循环,从而使全息图再现像的观察范围成倍增加.经实验成功地拍摄了观察视角为50°的一步彩虹全息图,并且应用效果较好.
In the light of very small viewing - angle of rainbow hologram and based on the basic principle of holographic recording and reconstructing, the method of one -step large viewing - angle rainbow holography with multiple reference beams is presented in this paper. Many cycles of colourful order in the reconstructed images can be obtained by this method, and the observing angle is increased many times. One -step rainbow hologram with about 50?viewing - angle is successfully taken in the experiment. A detailed theoretical analysis about reconstruction of multiple viewing - angle is also proposed.
