Abstract
A spectral distribution of incident light can be determined to increase collected spectral information. The spectral distribution of the incident light can be represented as a sum of spectral components after the incident light passes through a spectrum selective element. A signal at each color pixel of the spectrum selective element can be determined using, in part, the sum of the spectral components, where the spectral components are represented by a set of preliminary values. An error associated with the signal at each color pixel of the spectrum selective element is calculated. One or more perturbations are performed on each of the preliminary values and the error associated with the signal at each color pixel of the spectrum selective element is recalculated. The perturbations on each of the preliminary values is repeated until the error stabilizes within a predetermined range in order to assign the stabilized preliminary values as the spectral components in the incident light.
