Abstract
(EN)
A method of measuring a spectrum makes possible the recording and measuring of an extended spectrum section to be obtained by means of a concave grating, without losses at the interfaces between linear video signal shapers, in particular linear charged-coupled devices (CCD-registers). A spectrometer realizing the claimed method may be made small-size, movable and permissive to carry out spectrum measurements promptly. A small-size embodiment of the spectrometer makes possible, at the expense of a mirror to be arranged at the center of the Rowland circle, further decrease in its overall dimensions by a factor of two. The method contemplates a preliminary division of a flux of radiation to be investigated into two parts, which are directed toward a grating separately through two slits (3) being displaced with respect to each other in the direction being perpendicular to the plane of the Rowland circle (2), and then toward different linear video signal shapers (6), while forming on one linear video signal shaper, from one flux part, a spectrum section being a continuous extension of a spectrum section to be formed on the other linear video signal shaper from the other flux part.

Un procédé pour mesurer le spectre permet l'enregistrement et la mesure d'une section de spectre étendue, effectués au moyen d'une grille concave, sans pertes aux interfaces entre des formateurs de signaux vidéo linéaires tels que notamment les dispositifs à transfert de charge (registres CCD). Un spectromètre qui met en oeuvre le procédé de l'invention peut être de petite taille, mobile et permettre d'effectuer des mesures de spectre rapidement. Un mode de réalisation d'un spectromètre compact permet, grâce au miroir ménagé au centre du cercle de Rowland, de réduire davantage ces dimensions globales par un facteur de deux. Le procédé propose une division préliminaire en deux parties d'un flux de rayonnement examiné, les deux parties du flux étant dirigées séparément vers une grille à travers deux fentes (3) déplacées l'une par rapport à l'autre dans la direction perpendiculaire au plan du cercle de Rowland (2), puis vers les formateurs de signaux vidéo linéaires (6), alors que l'un des formateurs de signaux vidéo linéaires forme sur la base d'une partie du flux une partie de spectre qui constitue une extension continue d'une partie du spectre qui est formée sur l'autre formateur de signaux vidéo linéaires sur la base de l'autre partie du flux.
