Title
(EN) STEREOSCOPIC VIEWER
(FR) APPAREIL D'EXAMEN VISUEL STEREOSCOPIQUE
Abstract
(EN)
A stereoscopic viewer which enables an observer to observe images obtained through both a stereomicroscope and a stereoscopic fiberscope. When this stereoscopic viewer is used, the observer can see images obtained through both the stereomicroscope and stereoscopic fiberscope without moving his eye from an eye-piece section. In the stereoscopic viewer, a reflection mirror is provided in an optical path switching section or optical path. This stereoscopic viewer can be used for surgical operations, etc.
(FR)
L'invention concerne un appareil d'examen visuel stéréoscopique qui permet à un observateur d'observer des images par un stéréomicroscope et également par un fibroscope stéréoscopique. Lorsqu'il utilise cet appareil d'examen visuel stéréoscopique, l'observateur peut voir les images obtenues par le stéréomicroscope et également par le fibroscope stéréoscopique sans avoir à déplacer son oeil de l'oculaire. L'appareil d'examen visuel comporte un miroir réfléchissant qui est disposé sur le trajet optique et qui permet de commuter. Cet appareil d'examen visuel peut être utilisé pour les opérations chirurgicales, etc.
