Abstract
An optical device is disclosed and includes an optical sensor, a plurality of photosensitive pixels disposed on the optical sensor, a wavelength-selective optical filter in optical communication with the photosensitive pixels, and a plurality of spatially-variant written regions disposed in the optical filter, the written regions having a transmission spectrum and each of the written regions being larger than each of the pixels.

An optical device, comprising:
- an optical sensor;
- a plurality of photosensitive pixels disposed on the optical sensor;
- a wavelength-selective optical filter in optical communication with the photosensitive pixels;
- and
- a plurality of spatially-variant written regions disposed in the optical filter, the written regions having a transmission spectrum and each of the written regions being larger than each of the pixels.
An optical device, comprising:
- an optical sensor;
- a plurality of photosensitive pixels disposed on the optical sensor;
- a wavelength-selective optical filter in optical communication with the photosensitive pixels;
- a plurality of spatially-variant written regions disposed in the optical filter, the written regions having a transmission spectrum and each of the written regions being larger than each of the pixels;
- and
- an angle-selective filter in optical communication with the optical sensor and optical filter.
An optical device, comprising:
- an optical sensor;
- a plurality of photosensitive pixels disposed on the optical sensor;
- a wavelength-selective optical filter in optical communication with the photosensitive pixels;
- a first plurality of spatially-variant areas disposed in the optical filter;
- and
- a second plurality of spatially-variant areas disposed in the optical filter, the areas of the first plurality of spatially-variant areas having a transmission spectrum different from that of the areas of the second plurality of spatially-variant areas.
