Ultrathin flat meta-optics have shown great promise for holography in recent years. However, most of the reported meta-optical holograms rely on only phase modulation and neglect the amplitude information. Modulation of both amplitude and phase in meta-optics requires either polarization-sensitive meta-atoms or complex scatterers with stringent fabrication requirements. Additionally, almost all of the meta-optical holograms were measured under laser illumination. Here, we adopt the concept of double-phase holography, to report polarization-independent holography with both amplitude and phase modulation, using dielectric meta-optics. We validate the implementation of complex phase hologram by measuring an improvement of structural similarity of the reconstructed hologram by nearly 3 times over phase-only holograms. Finally, we demonstrate that meta-optical holography can also be realized using partially incoherent light from a light-emitting diode. This observation can significantly reduce the alignment complexity and speckles in laser-based meta-optical holography.
