Abstract: PROBLEM TO BE SOLVED: To provide a method for calibrating a spectrometer.SOLUTION: A spectrometer 500 comprises a Fabry-Perot interferometer 100 and an image sensor 200 having sensitivity to colors. The interferometer has a first transmission peak and a second transmission peak. The method for determining a calibration parameter of the spectrometer includes the steps of: providing a first calibration laser beam LB 11 having a narrow spectral peak; obtaining first detector signal values Sand Sfrom the image sensor by making the first calibration laser beam enter the spectrometer when a reference spectral peak is in the vicinity of a first spectral position λ; obtaining second detector signal values Sand Sfrom the image sensor by making the first calibration laser beam enter the spectrometer when the reference spectral peak is in the vicinity of a second spectral position λ; providing a second calibration laser beam having a wide band width; and obtaining third detector signal values Sand Sfrom the image sensor by making the second calibration laser beam enter the spectrometer.

Abstract: The invention relates to a system and a method for optical measurement of a target, wherein the target is illuminated, either actively illuminated, reflecting ambient light, or self illuminating, and a measurement light beam received from the target or through it is detected. The prior art optical measurement systems generally include mechanical filter wheels and photomultiplier tubes, which cause the equipment to be expensive, large-sized and often not sufficiently accurate and stable. The objective of the invention is achieved with a solution, in which the illuminating light beam and/or measurement light beam is led through a Fabry-Perot interferometer or a set of two or more Fabry-Perot Interferometers, and the Fabry-Perot interferometer or a set of two or more Fabry-Perot Interferometers is controlled into different modes during the measurement of a single target. The invention can be applied in optical measurements where, for example, reflectance, absorption of fluorescence of the target is measured.
