Abstract[English]
In certain embodiments, an ophthalmic laser surgical system for imaging and treating a target in an eye includes a digital micromirror device (DMD) confocal microscope, a laser device, and a computer. The DMD confocal microscope generates of images of the eye and includes a light source, a DMD device, and an image sensor. The light source provides a microscope imaging beam. The DMD device directs the microscope imaging beam along an imaging path towards the eye, receives the microscope imaging beam reflected from the eye, and rejects light of the reflected microscope imaging beam that is not from an image plane to scan the microscope imaging beam. The image sensor detects the scanned microscope imaging beam to generate the images of the eye. The laser device directs a laser beam along a laser beam path towards the target in the eye.[French]
Dans certains modes de réalisation, l'invention concerne un système chirurgical laser ophtalmique pour l'imagerie et le traitement d'une cible dans un oeil comprenant un microscope confocal à dispositif à micromiroir numérique (DMD), un dispositif laser et un ordinateur. Le microscope confocal DMD génère des images de l'oeil et comprend une source lumineuse, un dispositif DMD et un capteur d'image. La source lumineuse fournit un faisceau d'imagerie de microscope. Le dispositif DMD dirige le faisceau d'imagerie de microscope le long d'un trajet d'imagerie vers l'oeil, reçoit le faisceau d'imagerie de microscope réfléchi par l'oeil et rejette la lumière du faisceau d'imagerie de microscope réfléchi qui ne provient pas d'un plan d'image pour balayer le faisceau d'imagerie de microscope. Le capteur d'image détecte le faisceau d'imagerie de microscope balayé pour générer les images de l'oeil. Le dispositif laser dirige un faisceau laser le long d'un trajet de faisceau laser vers la cible de l'oeil.
