SPECTROSCOPIC ANALYSIS

摘要

The invention relates to an analyser 10 for characterising a sample comprising : an integrated laser 211/11 for emitting electromagnetic radiation 201a-f in at least one beam along a single-mode (SM) and polarisation maintaining (PM) channel at a sample 16, the electromagnetic radiation comprising at least two different wavelengths, a sample detector 17 that detects affected electromagnetic radiation resulting from the emitted electromagnetic radiation affected by the sample and provides output representing the detected affected radiation, and a processor 18 for characterising the sample from the detector output representing the detected affected electromagnetic radiation.
