Abstract
(EN)
An interferometer comprising a base (12) forming an interior, and first and second optical members (14 and 16) located in the interior of the base. The interferometer further comprises a first retainer assembly (20) connecting the first optical member to the base, translation means (24) for moving the second optical member (16) relative the first optical member (14), to vary the distance between the first and second optical members, and a second retainer assembly (22) connecting the second optical member to the translation means (24). The preferred mechanical configuration and design features of the interferometer produce a very durable instrument that can rapidly scan and accurately filter light across a wide bandwidth. This uniquely designed instrument combines high speed switching, high resolution, wide bandwidth, and adjustable damping capabilities in a durable flight capable instrument.

Cet interféromètre comprend une base (12) délimitant un espace intérieur dans lequel on a placé des premier et second éléments (4 et 6) optiques. Il comprend également un premier ensemble de retenue (20) reliant le premier élément optique à la base, des moyens (24) de translation destinés à déplacer le second élément (16) optique par rapport au premier (14), afin de faire varier la distance entre ces deux éléments, ainsi qu'un second ensemble de retenue (22) reliant le second élément optique aux moyens (24) de translation. La configuration mécanique préférée et les caractéristiques de conception de cet interféromètre en font un instrument très solide qui peut rapidement balayer et filtrer de manière précise la lumière à travers une grande largeur de bande. Cette conception unique combine une commutation rapide, une grande largeur de bande, une haute résolution ainsi que des possibilités d'amortissement réglable, dans un instrument solide, susceptible être placé à bord d'un aéronef.
