Title (EN) HAND-HELD LASER SCANNER
(FR) SCANNER PORTATIF AU LASER
Abstract:
(EN) A surgical laser scanner (10) having optics that scans a pulsed laser beam onto a target tissue is disclosed. The laser scanner has a lens and a scanning mirror or mirrors (60, 62) located upstream of the lens at a distance substantially equal to the focal length of the lens. The laser beam hits the scanning mirror and is reflected onto the lens (18) in a pattern defined by sequential positions of the scanning mirror. The laser beam is projected onto the target tissue by the lens in a direction parallel to the optical axis of the lens. The projected pattern has a constant size regardless of the distance between the laser scanner and the target tissue.
(FR) La présente invention décrit un scanner (10) chirurgical au laser équipé d'un instrument optique qui balaye un rayon laser pulsé sur un tissu cible. Le scanner au laser est équipé d'une lentille et d'un ou plusieurs miroirs (60, 62) de balayage situés en amont de la lentille à une distance sensiblement égale à la longueur focale de la lentille. Le rayon laser touche le miroir de balayage et se reflète sur la lentille (18) pour former un motif défini par les positions séquentielles du miroir de balayage. Le rayon laser est projeté par la lentille sur le tissu cible dans une direction parallèle à l'axe optique de la lentille. Le motif projeté a une taille constante, quelle que soit la distance qui sépare le scanner au laser du tissu cible.
