Fig. 16.  Categories of simple optical imaging techniques. In clockwise order, they are: Depth imaging, e.g., PhaseCam3D[36], the achromatic meta-lens array depth-sensing system[160]; high resolution and super-resolution imaging, e.g., DOE designed by end-to-end optimization for super-resolution[156], imaging by the FlatScope prototype and computational reconstruction of the image[71]; large depth of field imaging, e.g., the multi-level diffractive lens that exhibits extreme-depth-of-focus imaging[161], light-field imaging system enabled by the spin-multiplexed metalens array[162]; wide field-of-view imaging, e.g., the on-chip integrated μ-CE camera[163], the on-chip 180°×360° imaging system[164], metalens array integrated wide-angle camera[108].
