Abstract: front page image
(EN)A rotary spectrometer including a plurality of input ports. Each input port may be arranged to receive an optical waveguide carrying electromagnetic radiation. The spectrometer also includes a plurality of optical bandpass filters, which are housed on a first body that rotates under the control of a motor so that each optical bandpass filter may be brought into alignment with each input port. Further, the spectrometer includes a plurality of detector circuits disposed on a second body that rotates with the first body. Each detector circuit is optoelectrically coupled to one of the plurality of optical bandpass filters, thereby resulting in each detector circuit being dedicated to responding to a range of wavelengths determined by the bandpass filter to which it is optoelectrically coupled.
(FR)L'invention porte sur un spectromètre tournant comportant: plusieurs orifices d'entrée recevant chacune un guide d'ondes optique transportant des radiations électromagnétiques; et plusieurs filtres passe bande optiques placés dans un premier corps tournant mu par un moteur, de manière à ce que chacun des filtres vienne s'aligner sur chacun des orifices d'entrée. Le spectromètre comporte en outre plusieurs circuits de détection, placés sur un deuxième corps tournant avec le premier, et couplés chacun optoélectriquement à l'un des différents filtres. Il en résulte que chacun des circuits de détection répond spécifiquement à une plage de longueur d'onde déterminée par le filtre auquel il est couplé optoélectriquement.
