Numerical Study of Color Rainbow Hologram Reconstruction for Near-eye Color Display

Color rainbow holographic near-eye display with none-overlapping frequency components from color object has been proposed. The resolution, however, is low due to the very small bandwidth of object information used in the calculation. Numerical simulation methods for color rainbow hologram calculation and simulation that allow a certain overlap in the frequency domain is demonstrated in this study to improve the image quality of reconstructed image of color rainbow hologram. Through optical experiments, it has been proved that allowing higher recording bandwidth can improve the display quality
