Optical design of a hyperspectral imaging system using dispersion engineered metasurface

Not Accessible

Your library or personal account may give you access

Abstract

An optical metasurface with a diameter of 175 microns that simultaneously focuses and separates a continuum of wavelengths over a 100 nm bandwidth is presented. The evolution of the point spread function over 20 degrees of incidence makes this component suitable for hyperspectral imaging applications.
