Abstract: The present invention concerns a system and method for identifying and implementing a correction to spectrometer measurements in order to compensate for errors in the measurement values due to second order diffracted light. The present invention in one configuration, measures light reflectance percentages across the same wavelength range for at least one calibration target. From these measurements the portion of the reflectance values resulting from second order diffracted light is identified and corrected for, thereby generating a compensated measurement of the reflectance values of a sample. These compensated values are then provided to a user.

Abstract: In one example, an electronic signal is received from a target color measurement instrument that includes a plurality of color channels. A response of the target color measurement instrument to a light emitted by a target light emitting device is extracted from the signal. The response is calibrated to minimize a difference between the response and an output of a color matching function of a standard observer. Calibrating includes multiplying the response by a calibration matrix. The calibration matrix combines measurements of a first plurality of lights from a tunable light source and measurements of a second plurality of lights from the target light emitting device. A first subset of the measurements of the first plurality and second plurality of lights are made by the target color measurement instrument and a second subset of the measurements of the first plurality and second plurality of lights are made by a reference spectroradiometer.

Abstract: Aligning measurements of fluorescent spectral radiance factors taken by a first instrument with measurements of fluorescent spectral radiance factors taken by a second instrument, without knowledge of the matrix of bispectral luminescent radiance factor of any sample, includes obtaining a fluorescent spectral radiance factor of a reference sample, measured by the first instrument, obtaining the fluorescent spectral radiance factor of the reference sample, measured by the second instrument, obtaining a fluorescent spectral radiance factor of a test sample, measured by the first instrument, and estimating the fluorescent spectral radiance factor of the test sample that would be measured by the second instrument, based on the fluorescent spectral radiance factor of a reference sample, measured by the first instrument, on the fluorescent spectral radiance factor of the reference sample, measured by the second instrument, and on the fluorescent spectral radiance factor of the test sample, measured by the first instrument.

Abstract: Aligning measurements taken by a second color measurement instrument with measurements taken by first color measurement instrument, wherein the first instrument has access to a first set of standards but not a second set of standards, and the second instrument has access to the second set of standards but not the first set of standards, includes using a third color measurement instrument to generate a profile that mathematically transforms a value measured on the second set of standards to a value measured on the first set of standards, wherein the third instrument has access to the first and second sets of standards, mathematically transforming measurements of the second set of standards taken by the second instrument into virtual measurements of the first set of standards, using the profile, and aligning the measurements taken by the second instrument to the measurements taken by the first instrument, using the virtual measurements.
