A Method of Chromatic Aberration Compensation in Computer-Generated Holography Based on Digital Lens Area Sampling
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.
