Optical metasurfaces for imaging, sensing, and metrology

Optical metasurfaces are artificially structured surfaces that allow abrupt modification of the properties of light at sub-wavelength spatial scales. Due to the intimate control over light fields that they enable and also because of their ultra-thin character, they are finding increasing applications to simplify and miniaturize optical systems. In this regard, their use in imaging, sensing and metrology systems is among the most prominent ones. In this talk, we will present some of our recent results in the use of optical metasurfaces to achieve ultra-wide-angle, multispectral imaging and 3D metrology, and also share our recent development on their use for hyperspectral imaging in the MWIR for space applications. In all these topics, we will present the fundamental physical concepts behind the unique properties of these meta-optical devices, show pathways for their mass manufacturing and share thoughts on possible future avenues for this emerging technology.
