Abstract
A method for estimating an input spectrum from sensor data acquired by an optical sensor assembly, having an aperture, a Fabry-Perot interferometer, and an optical sensor element, the method including: obtaining first calibration data representative of a spectral response function of the optical sensor assembly for a first setting of the aperture; computing second calibration data from the first calibration data, the second calibration data being representative of a spectral response function of the optical sensor assembly for a second setting of the aperture, where the second setting corresponds to a setting applied during the acquiring of the sensor data; and estimating the input spectrum as a function of the second calibration data and the sensor data. Additionally, a corresponding system for estimating an input spectrum.
