Abstract: Aspects relate to on-line compensation of instrumental drifts in miniaturized spectrometers due to variations in environmental conditions and due to other sources of instrumental drift. The spectrometer may include a light modulator, a detector, and a processor. The spectrometer may further include a sensor configured to obtain a value of a condition contributing to instrumental drifts in the spectrometer. The processor may be configured to extract a set of correction parameters from a correction matrix associating a plurality of sets of correction parameters with sensor values based on the value and to apply the set of correction parameters to an output of the detector to produce a corrected spectrum of a sample under test. The correction matrix may be generated for the spectrometer or may be based on a global correction matrix fitted to the spectrometer.

Abstract: Aspects relate to a spectral modeling system for building chemometrics (calibration) models for spectral devices targeting ultra-wide-scale deployment. The spectral modeling system includes a spectral converter for generating a plurality of artificial spectra using spectral data of a plurality of samples measured by a subset of a plurality of spectral devices and spectral device characteristics representing spectral variations in the plurality of spectral devices. The spectral modeling system further includes a chemometrics engine for generating a chemometrics model for one or more parameters associated with the plurality of samples based on the spectral data and the plurality of artificial spectra.
