摘要
报道了一种降低计算全息图（ＣＧＨ）再现像量化噪声的一种新方法，它在原有罗曼Ⅲ型计算全息的基础上，在取样点数相同的前提下，利用显示器的固有分辨率，将全图分解成多幅子图作出，再应用图像处理软件重新拼接，从而降低了再现像量化噪声。
A new method for reducing graduated noise of CGH is described. On the basis of the CGH coded of Lohmann Ⅲ type, the whole CGH (64×64 sample points) is combined with 64 graphs (8×8 sample points). Using of the resolving power of CRT, the graduated noise is reduced. The experimental result is given.
