Abstract
A portable optical device (104) for transmitting an image to the eye (6) of an observer, includes: a display (1) disposed on the same side of the observer's head (7) as the eye, so as to emit the image in front of the observer's head; an ocular dioptric surface (3); and redirection elements (4, 5, 8, 9) for guiding the image towards the dioptric surface. The device is disposed such that the image strikes the dioptric surface (3) originating from the side of the nose in relation to the eye (6) and the dioptric surface (3) then reflects the image towards the eye (6). Such a device is particularly suitable for the production of glasses that can be used to display a virtual or augmented reality.

A portable optical device (103, 104) for transmitting an image to an eye (6) of an observer of said image, characterized in that it comprises:
- a display (1) arranged on one side of the observer's head (7) and emitting the image substantially forwardly of said head along an optical path (Δ″), said first side being the same side as said eye (6);
- an ocular dioptric surface (3);
- and
- redirecting means (4,5;
- 4,5,8,9) to guide the image between said display and said dioptric surface;
- said device being arranged so that the image originating from the side of the nose in relation to the eye (6) strikes said dioptric surface (3), said dioptric surface (3) then reflecting said image in the direction of said observer's eye (6).
A portable optical device (103, 104) for transmitting an image to an eye (6) of an observer of said image, comprising:
- a display (1) arranged on a first side of the observer's head (7) and emitting the image substantially forwardly of said head along an optical path (Δ″), said first side being the same side as the said eye (6);
- an ocular dioptric surface (3);
- and
- redirecting means (4,5;
- 4,5,8,9) to guide the image between said display and said dioptric surface,
- said device being arranged so that the image originating from the side of the nose in relation to the eye (6) strikes said dioptric surface (3), said dioptric surface (3) then reflecting said image in the direction of said observer's eye (6), and
- wherein the redirecting means (4,5;
- 4,5,8,9) comprise a side fold mirror (4) designed to reflect the image transversally in the direction of a second side of the observer's head, and a back-inverting mirror (5) arranged to redirect the image derived from the side fold mirror (4) in the direction of the dioptric surface (3).
A portable optical device (103, 104) that transmits an image to an eye (6) of an observer of said image, comprising:
- a light display (1) arranged on a first side of the observer's head (7) and located completely behind a front viewing portion of the observer's eyes, the light display originating and emitting the image along an optical path (Δ″) directed substantially forwardly of said head and in front of the front viewing portion of the observer's eyes, said first side being a same side as said eye (6);
- an ocular dioptric surface (3) located in front of the front viewing portion of the observer's eyes;
- and
- a pair of redirecting mirrors (4, 5) located in front of the front viewing portion of the observer's eyes in said optical path (Δ″) between the light display and the ocular dioptric surface (3), the redirecting mirrors (4,5) guiding the image in the image optical path (Δ″) exiting said light display to said dioptric surface (3),
- wherein a first mirror of said pair of redirecting mirrors is a back-inverting mirror (5) located in front of the front viewing portion of the observer's eyes, between the eyes in a region of an upper part of the observer's nose so that the image originating from image display back reflects from on a side of the nose closest to the eye (6) and strikes said dioptric surface (3), said dioptric surface (3) then reflecting said image in the direction of the eye (6).
