| 摘要 |
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. |
