Our laboratory has succeeded in fabricating spatially-multiplexed, high-transmittance multicolor 3D holograms using a single silicon nitride metasurface, however, the generation of crosstalk images has remained a problem. In this study, we attempted to add prism phases with different azimuth angles for each wavelength to the phase distribution of the object light to avoid overlap between the desired reconstructed image and the conjugate image at each wavelength.
