Abstract

The double-phase hologram adapts a complex wavefront for phase-type devices, but the reconstruction is plagued by the noise caused by spatial-shifting errors. To suppress the spatial-shifting noise, a spectral-envelope modulated approach is proposed. With this way, the capability of double-phase holograms is extended to encoding complex holograms generated with random phase, which is verified here with a colored holographic display of 2D photographs.
