Abstract
(EN)
The present invention relates to an apparatus and to a method of optical spectrum analysis of an optical spectrum of a light beam (4), comprising the steps of selecting a certain part of the optical spectrum of the light beam (4) to provide a filtered light beam (12), detecting the filtered light beam (12) to provide an electrical signal corresponding to a power amplitude (O(&lgr;)) of the filtered light beam (12), detecting the filtered light beam (12) to provide an electrical signal corresponding to a wavelength of the filtered light beam (12), and providing the power amplitude as a function of the wavelength of the filtered light beam (12).

L'invention concerne un appareil et un procédé d'analyse d'un spectre optique d'un faisceau lumineux (4), comprenant les étapes consistant à sélectionner une certaine partie du spectre optique du faisceau lumineux (4) de manière à obtenir un faisceau lumineux filtré (12), à détecter celui-ci (12) de manière à obtenir un signal électrique correspondant à une amplitude de puissance (O(?)) du faisceau lumineux filtré (12), à détecter celui-ci (12) de manière à obtenir un signal électrique correspondant à une longueur d'ondes du faisceau lumineux filtré (12) et à utiliser l'amplitude de puissance comme fonction de la longueur d'ondes du faisceau lumineux filtré (12).
