    Abstract: An imaging system and method are presents for use in reconstructing spectral data of an object. The imaging system comprises: an optical unit; a pixel array of a detector; and a data processor for receiving and processing image data indicative of light detected by the pixel array and generating reconstructed spectral data of the object being imaged. The optical unit is configured and operable for applying a predetermined coding to an input light field while creating an optical image thereof on a detection plane defined by the pixel array. Therefore, the image data is a function of the predetermined coding and a spectrum of the object to be determined.

    Abstract: In one aspect, an apparatus includes a first light source that applies first light having a first wavelength as a center wavelength to an object, a second light source that applies second light having a second wavelength as a center wavelength longer than the first wavelength to the object, an optical filter that includes first and second regions and that transmits third light produced by the first and second light each passed through or reflected by the object, first and second optical detectors that determine first and second amounts, respectively, of the third light passed through the first and second regions. The transmission ranges of spectral transmission curves of the first and second regions are located between the first wavelength and the second wavelength. The spectral transmission curve of the first region has a width at half maximum different from that of the spectral transmission curve of the second region.
