We propose a color holographic projection using the space-division method, which can reconstruct a two-dimensional color image by one hologram and avoid the superimposing of unwanted images on a wanted image. We calculated three holograms corresponding to red, green and blue, and then generated one hologram to add the three holograms. The three holograms were optimized by the Gerchberg-Saxton algorithm for improvement of reconstructed color images. We numerically evaluated the image quality of color reconstructed images in terms of the color space of YCbCr, and compared the quality of color reconstructed images by the space-division method with that of reconstructed color images using another color holographic projection method.
我们提出了一种使用空间分割法的彩色全息投影方法，该方法可以通过一张全息图重建二维彩色图像，并避免不需要的图像叠加在所需图像上。我们计算了对应于红、绿、蓝的三张全息图，然后生成一张全息图来叠加这三张全息图。通过格奇伯格 - 萨克斯顿算法对这三张全息图进行优化，以改善重建的彩色图像。我们根据YCbCr颜色空间对彩色重建图像的图像质量进行了数值评估，并将空间分割法重建的彩色图像质量与使用另一种彩色全息投影方法重建的彩色图像质量进行了比较。
