Title (EN) AN OPTICAL FILTER AND SPECTROMETER
(FR) FILTRE OPTIQUE ET SPECTROMÈTRE
Abstract: front page image
(EN)An optical filter is disclosed including two laterally variable bandpass filters stacked at a fixed distance from each other, so that the upstream filter functions as a spatial filter for the downstream filter. This happens because an oblique beam transmitted by the upstream filter is displaced laterally when impinging on the downstream filter. The lateral displacement causes a suppression of the oblique beam when transmission passbands at impinging locations of the oblique beam onto the upstream and downstream filters do not overlap.
(FR)L'invention concerne un filtre optique comprenant deux filtres passe-bande variables empilés latéralement à une distance fixe l'un de l'autre, de sorte que le filtre amont fonctionne comme un filtre spatial pour le filtre aval. Cela est dû au fait qu'un faisceau oblique transmis par le filtre amont est déplacé latéralement lorsqu'il est incident sur le filtre aval. Le déplacement latéral provoque une suppression du faisceau oblique lorsque les bandes passantes de transmission aux emplacement d'incidence du faisceau oblique sur les filtres amont et aval ne se chevauchent pas.
