摘　　要：提出了一种新型的傅里叶变换彩色编码彩虹合成全息图的自动化制作方法。根据数字合成全息原理和角度分区假颜色编码技术,三维模型经过图像处理得到拍摄图像并由空间光调制器显示。利用傅里叶变换全息光路和大数值孔径的物镜,在谱面上形成点元。借助计算机设定程序和运动控制系统,自动逐点干涉打印,实现大幅面大视角的彩色编码彩虹全息图的制作。An automatic method of making color coded synthesized Fourier transform hologram is proposed. The images of the three-dimensional model are processed by the principie of synthesized holography and the pseudo color coding method. The processed images are displayed by a spatial light modulator （SLM）. The light, through the SLM and the Fourier transform optical path and the lens with a large numerical aperture, forms a point pixel on the spectrum plane. By a computer and the program control systems, a large-format color-coded large-viewing angle rainbow hologram is produced pixel by pixel automatically.
