1. A hyperspectral imaging system for use in reconstructing spectral data of an object, the system comprising:

  • a pixel matrix of a detector;

    a dispersive unit in front of the pixel matrix, wherein the dispersive unit comprises a spectral filter; and

    a control system comprising;

    a controller for tuning the dispersive unit during n image acquisition sessions to provide n different spectral transmission profiles of the dispersive unit;

    wherein n is an integer that exceeds one;

    wherein the different spectral transmission profiles partially overlap; and

    a control unit in data communication with the detector and beingconfigured and operable for processing n image data pieces generated by the pixel matrix in said n image acquisition sessions respectively, each being indicative of a spectral image detected by the pixel matrix and corresponding to the different spectral transmission profiles of the dispersive unit, and determining, based on the different spectral transmission profiles of the dispersive unit, a reconstructed spectral data of the object.
