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.
Claims20
A portable optical device (103, 104) for transmitting an image to an eye (6) of an observer of the 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 the said head along an optical path (Δ″), the 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 the said display and the said dioptric surface;
- the said device being arranged so that the image originating from the side of the nose in relation to the eye (6) strikes the said dioptric surface (3), the said dioptric surface (3) then reflecting the said image in the direction of the said observer's eye (6).
A portable optical device (103, 104) for transmitting an image to an eye (6) of the observer of the said image, characterized in that it comprises:
- a display (1) arranged on a first side of the head (7) of the observer and emitting the image substantially forwardly of the said head along an optic path (Δ″), the said first side being the same as the side of the said eye (6);
- an ocular dioptric surface (3) of substantially elliptic shape, the major axis (Δ) of the ellipse being substantially transverse relative to the observer's head;
- the said device being arranged for provision to be made so that the centre of the pupil of the said eye (6) is substantially placed on a first focus (F′) of the dioptric surface (3), the second focus (F) of the dioptric surface being placed beyond the eye (6) in relation to the first side of the head, in the direction of the second side of the observer's head;
- the said device (103, 104) further comprising redirecting means (4,5;
- 4,5,8,9) to guide the image between the said display and the said dioptric surface, so that the central optic path is reflected by the dioptric surface (3) substantially backwards, substantially in the direction of the first focus (F′).
