optical guide and improves optics
2016
The present invention relates to an optical guide (1) for the display device close to the eye characterized in that it comprises a first guide element (6) having a light entry area, a second guide member ( 7) having an outlet area, the first guide element (6) being superimposed on said second guide element (7), and an optical coupling system between the first guide element (6) and the second guide element (7 ), characterized in that the first and second guide elements (6, 7) on a first portion of their length, a spacing (9) each other so as to define a thin layer of air between said guide elements ( 6, 7) extending between a first longitudinal end of the guide elements (6, 7) and the optical coupling system, the optical coupling system, located at a second longitudinal end of the first and second guide elements (6, 7), comprising a portio n-piece of said guide elements (6, 7) associated with an optical reflection member for propagating the light beams from the inlet to the outlet region.
