Characterization of the meta-optic. a Optical microscope image of the 1 mm aperture meta-optic. Different colors of the device correspond to different regions of pillars, which exhibit a structural color effect. b, c Top view SEM images of the fabricated device. Scale bars correspond to 10 μm and 1 μm, respectively. d SEM image at an oblique angle of 45°. The scale bar corresponds to 500 nm. e, f Full color scenes displayed on an OLED screen. g, h Corresponding images captured with the MOFIE at working distance of 10 mm. Scale bars correspond to 1 mm. Images displayed are without any computational deconvolution
