提出了一种合成真实物体全色计算全息图的新方法。在该方法中，基于三维傅里叶光谱的抛物线采样，考虑了计算全息图的合成过程和每个波长的放大倍数的调整。我们的方法只需要对物体进行一维(1-D)方位扫描，在合成过程中不需要任何近似，并且可以执行颜色重建所需的有效放大倍数调整。实验结果验证了该方法的原理和有效性。
A new method for synthesizing a full-color computer-generated hologram (CGH) of real-existing objects has been proposed. In this method, the synthesizing process of CGHs and the adjustments of magnifications for each wavelength are considered based on parabolic sampling of three-dimensional (3-D) Fourier spectra. Our method requires only one-dimensional (1-D) azimuth scanning of objects, does not require any approximations in the synthesizing process, and can perform efficient magnification adjustments required for color reconstruction. Experimental results have been presented to verify the principle and validity of this method.
