Abstract
Method and apparatus for determining direction from which electromagnetic radiation originates and spectral characteristics of the radiation are provided. Lenses, diffraction gratings, which may be present on the surface of the lenses, and mirrors direct radiation to a photodetector. Lens and grating parameters, along with the location, size, relative spacing and orientation of diffracted orders of radiation detected by the photodetector are used for determining direction from which the radiation originates.
