Abstract
A focusing device includes a substrate and a plurality of scatterers provided at both sides of the substrate. The scatterers on the both sides of the focusing device may correct geometric aberration, and thus, a field of view (FOV) of the focusing device may be widened.
Claims19
An imaging device comprising:
- a focusing device;
- and
- an optical detector configured to detect light incident through the focusing device,
- wherein the focusing device comprises,
- a substrate;
- a first thin lens provided at a first surface of the substrate and comprising a plurality of first scatterers;
- and
- a second thin lens provided at a second surface of the substrate and comprising a plurality of second scatterers,
- wherein the plurality of first scatterers of the first thin lens are configured to correct geometric aberration of the second thin lens, and
- wherein the optical detector includes an optical detection layer configured to convert optical signal incident on the optical detection layer into electric signal.
