Abstract
This talk will cover DARPA research programs that have made important strides in metasurfaces for imaging applications. The EXTREME program developed broadband achromatic metasurfaces and hybrid meta-optics for visible imaging applications, as well as actively tunable and hemispherical FOV metalenses in the infrared. The Enabling Night Vision in Eyeglass form factors (ENVision) program is leveraging these advances to develop planar night vision goggle systems based on meta-optics that are achromatic across two full IR bands and have enhanced FOV compared to state-of-the-art devices, all through a single common aperture.
