Title
(EN) INTEGRATED SPECTRAL PROBE FOR RAMAN, REFLECTANCE AND FLUORESCENCE SPECTRAL MEASUREMENTS
(FR) SONDE SPECTRALE INTÉGRÉE POUR SPECTRES RAMAN, MESURES SPECTRALES DE RÉFLECTANCE ET DE FLUORESCENCE
Abstract
(EN) Examples of a spectroscopy probe for performing measurements of Raman spectra, reflectance spectra and fluorescence spectra are disclosed. The integrated spectral probe can comprise one or more light sources to provide a white light illumination to generate reflectance spectra, an excitation light to generate an UV/visible fluorescence spectra and a narrow band NIR excitation to induce Raman spectra. The multiple modalities of spectral measurements can be performed within 2 seconds or less. Examples of methods of operating the integrated spectroscopy probe disclosed.
(FR) L'invention concerne des exemples d'une sonde de spectroscopie permettant d'effectuer des mesures de spectres Raman, de spectres de réflectance et de spectres de fluorescence. La sonde spectrale intégrée peut comporter une ou plusieurs sources lumineuses pour la mise en oeuvre d'un éclairage à lumière blanche pour générer des spectres de réflectance, une lumière d'excitation pour générer des spectres de fluorescence visible/UV et une excitation en proche infrarouge à bande étroite pour induire un spectre Raman. Les multiples modalités de mesures spectrales peuvent être effectuées dans les limites de 2 secondes ou moins. L'invention concerne aussi des exemples de procédés permettant d'utiliser la sonde de spectroscopie intégrée.
