Abstract[English]
A spectrometer assembly (1) for determining spectral information about incoming electromagnetic radiation (F) comprises a radiation conversion element (2) that comprises a non-centrosymmetric material to frequency-double at least a portion of the incoming electromagnetic radiation (F) as the incoming electromagnetic radiation (F) propagates through the radiation conversion element (2). The radiation conversion element (2) exhibits a spatially inhomogeneous structure such that the frequency-doubled electromagnetic radiation (SH) comprises components propagating in a plurality of different directions. The spectrometer assembly further comprises a detection unit (3) which is configured to record a spatial speckle image that is generated by spatial interference of the components of the frequency-doubled electromagnetic radiation (SH) with each other, and a computing unit (4) which is configured to retrieve spectral information about the electromagnetic radiation (F) based on said spatial speckle image.[French]
L'invention concerne un ensemble spectromètre (1) permettant de déterminer des informations spectrales concernant un rayonnement électromagnétique entrant (F) comprenant un élément de conversion de rayonnement (2) qui comprend un matériau non centrosymétrique permettant de doubler en fréquence au moins une partie du rayonnement électromagnétique entrant (F) lorsque le rayonnement électromagnétique entrant (F) se propage à travers l'élément de conversion de rayonnement (2). L'élément de conversion de rayonnement (2) présente une structure spatialement inhomogène de telle sorte que le rayonnement électromagnétique doublé en fréquence (SH) comprend des composantes qui se propagent dans une pluralité de directions différentes. L'ensemble spectromètre comprend en outre une unité de détection (3) qui est configurée pour enregistrer une image de speckle spatial qui est générée par interférence spatiale des composantes du rayonnement électromagnétique doublé en fréquence (SH) les unes avec les autres, et une unité de calcul (4) qui est configurée pour récupérer des informations spectrales concernant le rayonnement électromagnétique (F) sur la base de ladite image de speckle spatial.
