Claim 17:
18. A method for obtaining spectral data from a sensor, the method comprising:
receiving incident light;
scattering the incident light of a first wavelength range through a scattering layer of a first dispersion structure of a dispersion array, the scattering layer having a row of nanostructures creating scattered light of the first wavelength range;
dispersing a subset of the scattered light of a second wavelength range through a dispersion layer of the first dispersion structure, and creating dispersed light;
receiving the dispersed light on an image sensor; and
reconstructing spectral data from the dispersed light,
wherein the dispersion array includes the first dispersion structure and a second dispersion structure respectively including a first defect layer and a second defect layer, wherein thickness of the first defect layer is different from a thickness of the second defect layer.
