Abstract
(EN)
The present invention relates to a system and a method for processing electromagnetic radiation. In particular, the present invention relates to conversion of light, such as light (28) comprising image information (34), from one wavelength interval to another wavelength interval. More in particular, the present invention relates to wavelength conversion of incident light (28) by means of optical mixing with a laser beam in a non- linear crystal (14). The method according to the present invention comprises receiving incoming electromagnetic radiation (28) and a laser beam (12) in a non- linear crystal, setting a plurality of phase match conditions within the non- linear crystal (14), obtaining a plurality of images of the processed electromagnetic radiation (30), and providing a first combined image (42) comprising a first part of a first image and comprising a second part of a second image. The wavelength conversion is realized in an intra -cavity arrangement by for example sum- frequency generation between the intra-cavity laser light (12) and the in-coupled radiation (28).

La présente invention a trait à un système et à un procédé permettant de traiter un rayonnement électromagnétique. En particulier, la présente invention a trait à la conversion de la lumière, telle qu'une lumière (28) qui comprend des informations image (34), à partir d'un intervalle de longueur d'ondes vers un autre intervalle de longueur d'ondes. Plus particulièrement, la présente invention a trait à une conversion de longueur d'ondes de lumière incidente (28) au moyen d'un mélange optique avec un faisceau laser dans un cristal non linéaire (14). Le procédé selon la présente invention comprend les étapes consistant à recevoir un rayonnement électromagnétique entrant (28) et un faisceau laser (12) dans un cristal non linéaire, à définir une pluralité de conditions d'accord de phase à l'intérieur du cristal non linéaire (14), à obtenir une pluralité d'images du rayonnement électromagnétique traité (30) et à fournir une première image combinée (42) comprenant une première partie d'une première image et comprenant une seconde partie d'une seconde image. La conversion de longueur d'ondes est réalisée dans un agencement intra-cavité au moyen, par exemple, d'une génération de fréquence-somme entre la lumière laser intra-cavité (12) et le rayonnement couplé (28).
