摘要： A device for imaging light, or a source of the light, includes a window for receiving incident light from the source, at least one metasurface, and at least one wedge prism. The metasurface and the wedge prism form a Risley pair and are displaced independently of each other. Each of the metasurface and the wedge prism are operative to deflect the incident light at an angle that is different from an angle of light incident upon them. Each metasurface includes a plurality of sub-wavelength structures that are operative to interact with the incident light received from the window. The device also includes a lens system that is operative to transmit the incident light received from the at least one metasurface and the at least one wedge prism and focuses it on a focal plane.
