Multi-dimensional wavefront sensing using volumetric meta-optics

Kavli Affiliate: Andrei Faraon | First 5 Authors: Conner Ballew, Gregory Roberts, Andrei Faraon, , | Summary: The ideal imaging system would efficiently capture information about all fundamental properties light: intensity, direction, wavelength, and polarization. Most common imaging systems only map the spatial degrees of freedom of light onto a two dimensional image sensor, with […]
