Abstract[English]
In certain embodiments, an ophthalmic laser system includes a laser device, an ophthalmic microscope, and a controller. The laser device directs laser pulses towards a target within an eye. The target has a dimension. The laser device includes a laser configured to generate a laser beam and one or more laser beam multiplexers. A laser beam multiplexer modulates the laser beam to yield a pulse pattern of laser pulses. The pulse pattern has a coverage related to the dimension of the target to limit movement of the target. The ophthalmic microscope gathers light reflected from within the eye to yield an image of the eye. The controller instructs the laser device to direct the laser pulses towards the target to yield the pulse pattern of laser pulses.[French]
Dans certains modes de réalisation, un système laser ophtalmique comprend un dispositif laser, un microscope ophtalmique et un dispositif de commande. Le dispositif laser dirige des impulsions laser vers une cible à l'intérieur d'un œil. La cible a une dimension. Le dispositif laser comprend un laser conçu pour générer un faisceau laser et un ou plusieurs multiplexeurs de faisceau laser. Un multiplexeur de faisceau laser module le faisceau laser pour produire un motif d'impulsions d'impulsions laser. Le motif d'impulsion a une couverture liée à la dimension de la cible pour limiter le mouvement de la cible. Le microscope ophtalmique collecte la lumière réfléchie depuis l'intérieur de l'œil pour produire une image de l'œil. Le dispositif de commande ordonne au dispositif laser de diriger les impulsions laser vers la cible pour produire le motif d'impulsions d'impulsions laser.
