Title (EN) LED BASED CODED-SOURCE SPECTROMETER
(FR) SPECTROMÈTRE À SOURCE CODÉE À DEL
Abstract:
(EN) This invention relates to an LED based spectrometer which comprises a plurality of LED light sources that are capable of exhibiting different wavelengths and bandwidths, and the LED light sources are arranged in any convenient manner about a detector module, wherein the sample and reference optical paths are distinct from one another. In preferred embodiments, the LED sources are switched in a coded pattern or patterns corresponding to the Hadamard Complement scheme, or to a modified Hadamard Complement scheme.
(FR) La présente invention concerne un spectromètre à DEL comprenant une pluralité de sources lumineuses DEL capables de présenter différentes longueurs d'onde et différentes largeurs de bande; les sources lumineuses DEL sont ménagées de manière pratique autour d'un module détecteur, les trajets optiques de référence et échantillon étant distincts. Dans des modes de réalisation privilégiés, les sources DEL sont commutées dans un motif codé ou dans des motifs correspondant au schéma complémentaire d'Hadamard ou à un schéma complémentaire modifié.
