Ophthalmological display including a device for adjusting to the user's pupil spacing
View Patent ↗The invention relates to an ophthalmological display comprising an optical imager ( 10 ) for shaping light beams emitted by a miniature screen ( 20 ) of a light beam generator system and for directing the beams towards the eye (O) of the wearer to enable an image (I) to be viewed, said imager presenting an outlet optical axis (A). According to the invention, the display includes a device for adjusting to the user's pupil spacing, the device including means for adjusting the position of said image (I 1 , I 2 ) in a plane substantially perpendicular to said optical axis (A).
1. An opthalmological display comprising:
an optical imager for shaping light beams emitted by a miniature screen of a light beam generator system and for directing the beams towards the eye of the wearer so as to enable an image to be viewed, said imager presenting an outlet optical axis, said imager being integrated with a stationary lens for mounting in a frame for eyeglasses, wherein the display includes a device for adjusting to the user's pupil spacing, said device having a means for adjusting the position of said image in a plane substantially perpendicular to said optical axis, said adjustment device being internal to a housing containing said system for generating light beams, wherein said generator system comprises a stationary part, having connected thereto said screen by means of a moving connection in such a manner that said screen can be moved in translation in its longitudinal plane.
2. A display according to claim 1 , wherein said screen is secured to a second plate connected to said stationary part via said moving connection.
3. A display according to claim 1 , wherein said connection is an elastically-deformable element.
4. A display according to claim 3 , wherein said elastically-deformable element is constituted by a deformable fork.
5. A display according to any one of claim 1 , wherein said moving connection is adjustable by an actuator device.
6. A display according to claim 5 , wherein said actuator device is internal to said housing.
7. A display according to claim 6 , wherein said actuator device is constituted by a knob provided with an eccentric cylinder, said knob turning on a stationary portion of the housing and said eccentric cylinder being in abutment against said second plate.
8. A display according to claim 6 , wherein said actuator device is constituted by a screw screwed in a stationary portion of the housing and in abutment against said second plate.
9. A display according to claim 1 , wherein an adapter is in a reference position relative to the display and receives said generator system provided with its adjustment device by engagement of at least two studs.
10. A display according to claim 9 , wherein said adapter is secured to said stationary part.
11. A display according to claim 9 , wherein the connection between said system and said adapter is releasable.
12. A display according to claim 1 , wherein said stationary part carries an associated optical component.
