Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 14:
15. The system of claim 1, wherein the
non-transitory computer readable medium is configured to store
i) spectra I of interference fringes generated by spectrally-modulated broadband IR light upon illumination of the chemical targets, and
ii) library absorption spectra for at least one known concentration of each of the chemical targets, and

wherein the non-transitory computer readable medium is encoded with a computer program comprising instructions stored therein for causing the computer processor to perform an algorithm which allows the effective illumination spectrum Io to be modelled as an interpolation function and to become a free parameter when fitting the library absorption spectra for each of the chemical targets to the spectra I of interference fringes generated by spectrally-modulated broadband IR light upon illumination of the chemical targets.
