Abstract
According one embodiment, a millimeter-wave radiation imaging array includes a plurality of antenna elements configured to receive millimeter-wave radiative input. Each lenslet of a plurality of lenslets are coupled to one of the plurality of antenna elements such that no air exists between each lenslet and the one of the plurality of antenna elements. Each lenslet has a spherical portion being operable to direct the radiative input towards the one of the plurality of antenna elements. An energy detector is coupled to the plurality of antenna elements opposite the plurality of lenslets and operable to measure the radiative input received by the plurality of antenna elements.
