Abstract: The present invention discloses a light and thin tail lamp comprising a light guide structure and a lampshade, wherein the light guide structure is arranged in the lampshade, one surface of the light guide structure is an emergent surface, and the other surface of the light guide structure is a reflective surface; two incident surfaces are arranged on opposite positions at two sides of the light guide structure, at least one of the incident surfaces is provided with light sources, and rays emitted from the light sources enter the light guide structure through the incident surfaces; and the light sources are connected with a control circuit. The light and thin tail lamp disclosed by the present invention is reasonable in design, small in thickness, size and occupied space, and convenient to mount; and the light and thin tail lamp is high in brightness, uniform in light emergence and non-dazzling.

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.

Abstract: An optical unit (1) for augmented vision and augmented reality, which is to be placed in front of an eye of a user of the unit, includes a transparent or semitransparent screen (3), preferably a P-LED or TO-LED screen, and a unit (4) for collimating an image emitted by the screen toward the eye of the user, the collimating unit being a DOE, preferably an HOE, and the convergence function of the collimating unit being effective at a wavelength (FS) emitted by the screen.

Abstract: A method for generating retinal images using the stigmatism of the two foci (F, F?) of a substantially elliptical sight (E) with a semi-reflective surface, wherein a so-called object focus consisting of the diaphragm of a pinhole disc forming the convergence point of an image generated by a light-emitting display or a collimated light source is positioned adjacent to the first focus (F) of the substantially elliptical sight (E), a so-called image focus consisting of the pupil or the centre of the user's eye (OE) is positioned adjacent to the second focus (F?) of said substantially elliptical sight (E), and the image generated by said light-emitting display or said collimated light source and reflected by the semi-reflective surface of the substantially elliptical sight (E) is projected adjacent to the retina of the user's eye.
