Nano optics writ large

Glass & plastic lenses will slowly be replaced by metamaterials able to replicate the same image quality in form factors not able to be imagined until now.

Salt Grain-sized Cameras

The ultracompact camera we propose uses metasurface optics at the size of a coarse salt grain and can produce crisp, full-color images on par with a conventional compound camera lens 500,000 times larger in volume.

Metasurface Proxy Model

We learn a nano-optic by using an efficient differentiable proxy function that maps phase values to spatially varying PSFs. This allows our approach to be more than three orders of magnitude more efficient than full-wave simulation methods such as FTDT.

Siemens Resolution Chart

Siemens Resolution Star captures compared to heuristic designs by Colburn et al. and a refractive compound lens. Computational reconstruction with our neural nano-optic imager recovers spatial resolution in broadband almost matching the performance of a refractive compound lens. See Supplemental Material for USAF 1951 chart comparisons.
