Abstract
Disclosed is a method for infrared spectrum compression wherein a plurality of referenced spectrums each corresponding to one of a plurality of known substances is digitized to obtain a plurality of reference digitized spectrums. The intensity, location and width of each peak for each reference digitized spectrum then is identified and this information is stored. The stored information relating to each of the referenced digitized spectrums is used to compare with an unknown digitized spectrum of an unknown substance to identify the unknown substance.
Claims3
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.
