Patent

CA 2540710

The invention relates to an optical microscope, comprising, at least a light source, a carrier for an object to be examined, a detector for registering the illuminated object, and a light path that during operation runs substantially from the light source to the object and from the object to the detector, wherein a metallic thin film having a periodic hole array is placed in the light path between the light source and the object, and wherein the carrier of the object is provided with a drive to allow the same to be adjusted in the plane of the carrier, wherein the holes of the metallic thin film have a diameter that is smaller than approximately 250 nm, in that the drive is designed for adjusting the carrier for the object in an orientation perpendicular to the plane of the carrier, and in that a processing de- vice is provided that is connected with the detector for constructing a three- dimensional image of the object.

L'invention concerne un microscope optique comprenant au moins une source lumineuse, un support pour un objet à examiner, un détecteur pour enregistrer l'objet éclairé et une trajectoire lumineuse, qui, lors de son fonctionnement se déplace sensiblement de la source lumineuse à l'objet, et de l'objet au détecteur, un film mince métallique présentant un agencement de trous périodique étant placé sur la trajectoire lumineuse, entre la source et l'objet, et le support de l'objet étant doté d'un pilote pour permettre à cet objet d'être ajusté dans le plan du support. Les trous du film mince métallique présentent un diamètre inférieur à approximativement 250 nm. Le pilote est conçu pour ajuster le support de l'objet dans une orientation perpendiculaire au plan du support, et un dispositif de traitement est relié au détecteur pour créer une image tridimensionnelle de l'objet.
