Abstract:
1. A method of classifying measurement results in a multivariate optical computing system, the method comprising: receiving a first signal based on a first portion of an illumination light that has interacted with a sample, the first signal modified by at least one spectral element; receiving a second signal based on the first portion of the illumination light; separating a second portion of the illumination light from a first portion of the illumination light before the first portion of the illumination light has interacted with the sample; determining a baseline for the first signal and the second signal using a calibration signal from the second portion of the illumination light, the calibration signal modified by the at least one spectral element; and providing classifying information based on determining if the first signal and the second signal lie in a range of expected results.
