Classification: CPC G | IPC G

Claim 13:
14. An image sensor, comprising:
an aperture;
a dispersion array;
a lens;
an image sensor; and
a processor,
wherein the image sensor includes a first portion including a first set of pixels and a second portion including a second set of pixels,
wherein the first set of pixels are within a first angle from an axis of incident light from the dispersion array and the lens, and the second set of pixels are within a second angle from the axis of incident light from the dispersion array and the lens,
wherein the first set of pixels are configured to read scattered light within the first angle, and the second set of pixels are configured to read dispersed light within the second angle,
wherein, the dispersion array further comprises a first dispersion structure including a scattering layer and a dispersion layer, wherein the scattering layer includes a first row of nanostructures for scattering light of a first wavelength range, and the dispersion layer is configured to disperse light of a second wavelength range,
wherein the first row of nanostructures is positioned at a first angle different from a second angle of a second row of nanostructures associated with a second dispersion structure of the dispersion array.
