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.
提出了一种合成真实物体全彩色计算机生成全息图（CGH）的新方法。在该方法中，基于三维（3-D）傅里叶光谱的抛物线采样来考虑CGH的合成过程以及每个波长的放大倍数调整。我们的方法仅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高效放大倍数调整。已给出实验结果以验证该方法的原理和有效性。
