Resumen
Hyperspectral image based on double frequency comb. A method of generating a double comb signal of illumination frequencies that provides a train of low frequency interferograms (180) readable by a regular video camera (160) comprising N pixels and a sampling frequency of V Hz to extract information (170) hyperspectral, the procedure comprising providing a monochromatic signal, dividing the monochromatic signal into two divided monochromatic signals, shifting the frequency of each monochromatic signal with an offset frequency less than {IMAGE-01} Hz, generating two frequency combs that have a repetition difference of less than {PICTURE-02} Hz by non-linear modulation of the two divided monochromatic signals, generating the double illumination comb signal, illuminating a target and using a camera (160) to read the interferogram train frequency (180) of the reflected and/or transmitted illumination double comb signal of a sample and perform the tr Ansformed Fourier of the train of low-frequency interferograms (180) detected by each pixel of the N pixels to extract the hyperspectral information (170).
