Abstract
A device for color imaging including an optical sensor having light sensitive pixels with a metal film disposed over the light sensitive pixels. The metal film has a group of nano-holes arranged over the pixels according to a periodic lattice formation and is configured to pass light of a preselected first range of wavelengths. The group of nano-holes arranged over an adjoining group of pixels is configured to pass light having ranges of wavelengths different from the first range of wavelengths.
Claims14
A color imaging device comprising:
- an optical sensor having a plurality of pixels, each pixel of the plurality of pixels comprising a plurality of sub-pixels, wherein each sub-pixel of the plurality of sub-pixels are adapted to sense light;
- and
- a metal film on the optical sensor, the metal film having a group of nano-holes arranged over at least one sub-pixel according to a periodic lattice formation and configured to pass light having a preselected first range of wavelengths,
- wherein a group of nano-holes arranged over an adjoining sub-pixel is configured to pass light having ranges of wavelengths different from the first range of wavelengths.
