Fig. 2 Design principle and experimental configuration of meta-holography.
Design principle and experimental configuration of meta-holography. (A) Design principle for the holographic imaging. (B) Experimental setup for the reconstruction process. QWP, quarter-wave plate; CCD, charge-coupled device. (C) Phase diagram of the meta-hologram calculated by the GS algorithm corresponding to the flower holographic image. Scale bar, 500 μm. Color bar, phase shift. (D) Scanning electron microscope image of the nanoslit antennas. Scale bar, 1 μm. Xiong Li et al. Sci Adv 2016;2:e Copyright © 2016, The Authors
