    Abstract: Un spectromètre d'imagerie sert à fournir une image diffusée de la surface de la terre (utile pour des études scientifiques botaniques, géographiques, géologiques et hydrologiques) depuis une plate-forme volante. Le dispositif de spectrométrie peut être attaché à un télescope optique existant. Le spectromètre fournit une image à plan focal planaire qui peut être traitée de maintes façons, en utilisant par exemple une rangée d'éléments photosensibles. Le spectromètre comprend un système optique dans lequel les rayons de lumière sont dirigés à travers des prismes lorsqu'ils traversent les deux "branches" symétriques du spectromètre. Le spectromètre utilise un miroir réfléchissant concave et des ensembles de prismes ayant des surfaces parallèles d'entrée et de sortie. Dans un premier mode de réalisation, un seul ensemble de prismes est utilisé, alors que dans un deuxième mode de réalisation, une paire d'ensembles de prismes généralement identiques est utilisée.

    Abstract: A spatial Fourier transform spectrometer is disclosed (e.g., 350). The Fourier transform spectrometer includes a Fabry-Perot interferometer (e.g., 320, 420, 520) with first and second optical surfaces (e.g., 454, 458, and 554, 558). The gap (e.g., 462, 562) between the first and second optical surfaces spatially varies in a direction that is orthogonal to the optical axis (e.g., 466, 566, 666) of the Fourier transform spectrometer. The Fabry-Perot interferometer creates an interference pattern from input light. An image of the interference pattern is captured by a detector (e.g., 340, 640), which is communicatively coupled to a processor (e.g., 342). The processor is configured to process the interference pattern image to determine information about the spectral content of the input light.
