Abstract: A method for analyzing a spectral signature of a compound specimen is provided. The method includes illuminating a compound specimen with a light in a predetermined spectrum; obtaining a spectral signature of the compound specimen, the spectral signature including at least one light property of a plurality of wavelengths in the spectrum transmitted through the compound specimen; extracting characterizing features of the spectral signature, the characterizing features being light properties of predetermined wavelengths within the spectrum; and comparing the characterizing features with corresponding features stored in a database, the corresponding features are corresponding properties of an expected spectral signature of a specimen including an examined substance.

Abstract: A device for spectral analysis including a seat for holding therein a compound specimen; a light source for illuminating the compound specimen with a spectrum of light; and a detector configured for detecting light transmitted through or reflected from the biological sample, the detector including a pixel array having a plurality of pixels each of which being configured to detect intensity of one wavelength within the spectrum such that the pixel array obtains a spectral signature of the biological sample including intensities of wavelengths within the spectrum.
