Title: OPTICAL SYSTEM COMBINING IMAGE PRESENTATION AND EYE ANALYSIS
Abstract:
The invention concerns optical systems for presenting an image to a user. The system is characterised in that it comprises an image source (1) and an optical channel (4) transmitting said image to the user's eye (5). It also comprises an illumination (7) of the ocular fundus (5) and an imaging (10) of the illuminated ocular fundus, both using part of the optical channel (4). The system enables an analysis of the eye retina observing an image. It also enables, depending on the eye position, an adaptation of the visual information presented. The system partially mounted in a headset enables the presentation of image to a mobile user.
