【摘要】 本文提出一种新的计算机彩虹全息图,即无透镜夫琅和费型计算机彩虹全息图,介绍了它的基本原理及物体光波的数学描述,并以彩虹全息图的信息量出发,讨论了一般计算机彩虹全息图信息量的冗余度及减少冗余信息量的方法.最后给出了无透镜夫琅和费型计算机彩虹全息图的实验结果.更多还原

【Abstract】 A new type of computer generated rainbow hologram (CRH), called Lens-less Fraunhofer Computer Generated Eainbow Hologram (LLFCRH), is proposed in this paper.The principle of LLFOEH and the math mode of object wave are analyzed.Based on the information of holograms, the information of ordinary CRH, the redundancy of information and the related techniques for reducint the redundant information are discussed. The experimental results are shown.更多还原
