一种用于获取真实物体的全彩三维 (3-D) 图像的新方法已经开发出来。该方法基于从 3D 傅里叶光谱中提取信息，该光谱是根据使用白光源记录的多个投影图像计算得出的。三种颜色的 3-D 傅里叶光谱是通过彩色 CCD 相机记录的投影图像分别获得的。然后根据这些傅立叶光谱合成三个计算机生成的全息图（CGH）。给出了所得的数字和光学重建的全彩图像。
A novel method for the procurement of full-color three-dimensional (3-D) images of real objects has been developed. This method is based on extracting information from 3-D Fourier spectra, which are calculated from several projection images recorded using a white light source. 3-D Fourier spectra for three colors were obtained separately for projection images recorded with a color-CCD camera. Three computer-generated holograms (CGHs) were then synthesized from those Fourier spectra. The resulting numerically and optically reconstructed full-color images are presented.
