Abstract: A method includes decomposing a training set to obtain a principal component matrix having a plurality of principal component vectors. The method also includes variably rejecting portions of a sample spectrum vector that do not correspond to a selected one of the plurality of principal component vectors by incrementally providing a coefficient indicative of the weighting of the selected principal component vector for selected sub-regions. A corrected spectrum vector can be obtained by excluding certain sub-regions of the sample spectrum vector and corresponding principal component vector, multiplying the sample spectrum vector with the principal component matrix for non-excluded sub-regions, providing a predicted interference vector, and subtracting the predicted interference vector from the sample spectrum vector.

Abstract: Systems and techniques for optical spectrometer detection using, for example, IR spectroscopy components and Raman spectroscopy components are described. For instance, a system includes a first electromagnetic radiation source configured to illuminate a sample with a first portion of electromagnetic radiation in a first region of the electromagnetic spectrum (e.g., an IR source) and a second electromagnetic radiation source configured to illuminate a sample with a second portion of electromagnetic radiation in a second substantially monochromatic region of the electromagnetic spectrum (e.g., a laser source). The system also includes a detector module configured to detect a sample constituent of a sample by analyzing a characteristic of electromagnetic radiation reflected from the sample associated with the first electromagnetic radiation source and a characteristic of electromagnetic radiation reflected from the sample associated with the second electromagnetic radiation source.
