Abstract
The augmented-reality optical device (1) includes: a display (2) for emitting at least one image in the form of a beam; an optical surface (4) arranged essentially transversely to the main optical axis such that it deflects the image towards the eye; a semi-reflective plate (3) for deflecting the image between the display and the optical surface; and a polarizer (6) for eliminating the parasite light.
Claims10
Augmented-reality optical device (1), which comprises:
- a display (2) for emitting at least one image in the form of a beam;
- means for positioning said display laterally relative to an eye (10) of a user, so that said display emits said image substantially transversely relative to a principal optical axis (X1) of said eye;
- an ocular return sight (4), disposed substantially transversely to said principal optical axis so that it returns the image in the direction of the eye;
- means (3) for redirecting said image between said display and said sight;
- and
- polarisation means (6, 21, 25) for eliminating stray light.
