1. An Imaging method for non-destructive analysis of paintings and monuments, hereunder described with the term “object” comprising: a) exposing the object to a polychromatic light beam, which includes wavelengths ranging from the ultraviolet through the mid-infrared part of the spectrum; b) generating a board band image of the object in response to the incident light beam, which image is consisted from photons with wavelengths laying within the spectral sensitivity limits of ultraviolet, visible, near- and mid-infrared detectors and imaging photon energy converters, used for object's image capturing; c) generating a plurality of narrow band images corresponding to the broad band image of the object and comprising the intensity of said broad band image captured in the narrow bands of shorter than the detector's sensitivity spectral range, where for any spatial location of the examined area, the light intensities expressed by the materials constituting the object in narrow spectral bands in response to the incident light beam, are compared with the light intensities expressed by object material models at the same narrow spectral bands and under the same illumination and imaging conditions, thus enabling the determination and mapping of compositional characteristics of the materials used to create the object.
