CA 2268196

An optical system combines a first image formed by a main lens (300) with a second image provided by an electronic display, slide, or other image source (320). The image combining system includes one or more inserts such as a set of reflecting image combiners to redirect light on an optical pathway within the main lens to the user's eye. The image combining system is highly compact, allowing the integration of a display system with eyeglasses or a face mask, such as a diver's mask. A number of implementations of the optical system make possible other types of image integration including uses in image acquisition systems such as cameras.

Système optique combinant une première image, obtenue par une lentille principale (300), avec une seconde image obtenue par un affichage électronique, une diapositive ou autre source d'image (320). Le système de combinaison d'images comprend un ou plusieurs éléments d'insertion tels qu'un ensemble de combineurs d'images à surfaces réfléchissantes permettant de rediriger la lumière vers l'oeil de l'utilisateur, sur un chemin optique, dans la lentille principale. Le système de combinaison d'images est extrêmement compact, ce qui permet d'intégrer un système d'affichage à lunettes ou un masque tel qu'un masque de plongée. Un certain nombre de configurations du système optique rend possible d'autres types d'intégration d'images, y compris des utilisations dans des systèmes d'acquisition d'images tels que des caméras.
