Abstract: A photonic spectrometry device is provided. The photonic spectrometry device includes at least one sensor capable of detecting photons, at least one photon-emitting calibrating source having a reference spectral line, and processing means capable of providing, for the or each sensor, a measurement spectrum corresponding to the measurements, made by the or each sensor, of the radiation from a product during a time interval, and establishing, on the basis of the or each measurement spectrum, a net corrected spectrum according to a measured characteristic line corresponding to the or each calibrating source. The or each calibrating source is positioned outside the or each sensor.

Abstract: A photonic spectrometry device is provided. The photonic spectrometry device comprises several identical spectrometers each spectrometer comprising a radiation sensor and being capable of providing a measurement spectrum corresponding to the measurements of the sensor during a time interval, the spectrometers being capable of performing measurements simultaneously on one same radiation-emitting product and of providing measurement spectra for one same time interval, and a processor capable of determining a net spectrum from each of the measurement spectra provided by the spectrometers for one same time interval, and of determining a global spectrum resulting from the summation of the net spectra determined for one same time interval.
