Title
(EN) PIXELATED ARRAY OPTICS FOR MIXED MODE SURGICAL LASER ILLUMINATION
(FR) ÉLÉMENTS OPTIQUES EN RÉSEAU PIXELISÉ POUR ÉCLAIRAGE LASER CHIRURGICAL EN MODE MIXTE
Abstract
(EN)
Pixelated array optics for mode mixing may be used to homogenize different modes in an optical fiber used for surgical illumination. A pixelated phase array, such as a digital micromirror device or an LCD phase plate, may impart motion to an incident beam entering the optical fiber to generate a homogeneous illumination field from a coherent light source.
(FR)
L'invention concerne des éléments optiques en réseau pixelisé pour mélange de modes peuvent être utilisés pour homogénéiser différents modes dans une fibre optique servant à l'éclairage chirurgical. Un réseau pixelisé à commande de phase, tel qu'un dispositif à micromiroir numérique ou une lame de phase LCD, peut imprimer un mouvement à un faisceau incident pénétrant dans la fibre optique pour créer un champ d'éclairage homogène à partir d'une source de lumière cohérente.
