Abstract
A method and a system are provided for obtaining improved spectra recovery results of a measurement of a sample through the use of a calibration matrix obtained from calibration measurement values using at least one illumination source. By calculating the reflectance spectrum of a collection of calibration samples across several rounds of measurements and cascading the results, an improved calibration matrix can be used to convert the sample measurement values to more accurate results.
