Title (EN) SPECTROMETER
(FR) SPECTROMÈTRE
Abstract:
(EN) A spectrometer for temporally separating electromagnetic radiation (10) includes a cavity (105) having first and second reflecting mirrors (1, 2, 4, 5). The first mirror (1, 2) has an aperture (8) arranged to allow electromagnetic radiation (10) to be input into the cavity (105). The spectrometer also includes an imaging device (3) between the first and second mirrors (1, 2, 4, 5) that defines an optical axis of the cavity (105) and performs spatial Fourier transforms of the electromagnetic radiation (10). The first and/or second mirrors (1, 2, 4, 5) has a normal that is arranged at a non-parallel angle to the optical axis, such that the position and/or angle of incidence of electromagnetic radiation (10) on the second mirror is shifted after each round trip. The second mirror (4, 5) allows a wavelength component (14) of the electromagnetic radiation to be output from the cavity (105) when the position and/or angle of incidence of the electromagnetic radiation on the second mirror (4,) after one or more round trips of the cavity (105) exceeds a threshold.
(FR) L'invention concerne un spectromètre pour séparer temporairement un rayonnement électromagnétique (10), qui comprend une cavité (105) ayant des premier et second miroirs réfléchissants (1, 2, 4, 5). Le premier miroir (1, 2) a une ouverture (8) conçue pour permettre l'introduction d'un rayonnement électromagnétique (10) dans la cavité (105). Le spectromètre comprend également un dispositif d'imagerie (3) entre les premier et second miroirs (1, 2, 4, 5), qui délimite un axe optique de la cavité (105) et réalise des transformées de Fourier spatiales du rayonnement électromagnétique (10). Le premier et/ou le second miroir (1, 2, 4, 5) ont une normale qui est disposée à un angle non-parallèle à l'axe optique, de telle sorte que la position et/ou l'angle d'incidence du rayonnement électromagnétique (10) sur le second miroir est changé après chaque tour. Le second miroir (4, 5) permet à une composante de longueur d'onde (14) du rayonnement électromagnétique d'être délivrée depuis la cavité (105) lorsque la position et/ou l'angle d'incidence du rayonnement électromagnétique sur le second miroir (4,), après un ou plusieurs tours de la cavité (105), dépasse un seuil.
