Claims
- 1. A method for spectrum compression, comprising:
- producing a digitized spectrum for each of a plurality of known substances with the digitized spectra each having a plurality of absorbance bands on a wavelength axis, each of the digitized spectra comprising a reference digitized spectrum;
- separating the absorbance bands of the reference digitized spectrum, thereby creating separated absorbance bands;
- locating the separated absorbance bands on the wavelength axis;
- curve-fitting the separated absorbance bands to correspond to the absorbance bands of the reference digitized spectrum, creating thereby a plurality of curve-fitted absorbance bands comprising a restored reference spectrum;
- identifying an intensity, location and width of each curve-fitted absorbance band comprising the restored reference spectrum; and
- storing the intensity, location and width of the curve fitted absorbance bands, thereby creating a stored compressed reference spectrum corresponding to each of the reference digitized spectra.
- 2. The method of claim 1 further comprising;
- obtaining a digitized spectrum of an unknown substance comprising an unknown digitized spectrum; and
- identifying the unknown substance using the unknown digitized spectrum and the compressed reference spectra.
- 3. The method of claim 1 further comprising:
- obtaining a digitized spectrum of an unknown substance comprising an unknown digitized spectrum;
- retrieving at least a portion of the stored compressed reference spectra;
- using the intensity, location and width of the curve-fitted absorbance bands comprising the stored compressed reference spectra to recreate the reference spectra, creating thereby restored reference spectra; and
- comparing the restored reference spectra with the unknown digitized spectrum to identify the unknown substance.
