针对计算全息彩色光电再现过程中，由成像区域中心点不重合引起的色差问题，提出一种基于数字透镜区域采样的补偿方法。通过改变数字透镜的采样区域，实现再现像位置的移动，再现像的偏移量与数字透镜采样区域的偏移量在水平和竖直方向等大反向。实验使用单个空间光调制器的空分复用法，以蓝色再现像为基准，调节红色和绿色再现像的位置，实现了计算全息色差的补偿，结果证明了所述方法的可行性。

For the chromatic aberration problem caused by the uncoincidence of reconstructed image′s center in the procession of color optoelectronic reconstruction of computer-generated holography, a compensation method based on digital lens area sampling is proposed. By changing the sampling area of digital lens, the reconstructed image′s position can be changed. The offset distance of reconstructed image is reversely equal to the offset distance of the sampling area in horizontal and vertical directions. In the experiment, a single spatial light modulator within spatial- multiplexing method is used by setting the blue reconstructed image as standard and readjusting the positions of red and green reconstructed images, the chromatic aberration compensation can be achieved. The experiment verifies the feasibility of the proposed method.
