Abstract

We demonstrate the design and 3D printing of a large-scale complex-amplitude metasurface hologram for orbital angular momentum-multiplexing holography. The independent and complete amplitude and phase manipulation allows the lensless reconstruction of 200 OAM-dependent orthogonal image frames for holographic videos displays.
