Abstract
An image sensor includes a substrate, thin lenses disposed on a first surface of the substrate and configured to concentrate lights incident on the first surface, and light-sensing cells disposed on a second surface of the substrate, the second surface facing the first surface, and the light-sensing cells being configured to sense lights passing through the thin lenses, and generate electrical signals based on the sensed lights. A first thin lens and second thin lens of the thin lenses are configured to concentrate a first light and a second light, respectively, of the incident lights onto the light-sensing cells, the first light having a different wavelength than the second light.
Claims20
An image sensor comprising:
- a substrate;
- a first thin lens configured to concentrate light of a first wavelength and comprising a plurality of first scatterers disposed on the substrate;
- a second thin lens configured to concentrate light of a second wavelength, and comprising a plurality of second scatterers disposed on the substrate;
- and
- a plurality of light-sensing cells configured to sense the light concentrated by the first thin lens and the second thin lens,
- wherein at least two of the plurality of first scatterers or at least two of the plurality of second scatterers have different heights to each other.
