Abstract[English]
An image light guide system for conveying a virtual image including a first waveguide and a second waveguide. A first in-coupling diffractive optic formed along the first waveguide and operable to diffract a first set of image-bearing light beams into the first waveguide in an angularly encoded form. A second in-coupling diffractive optic formed along the first waveguide and operable to diffract a second set of image-bearing light beams into the first waveguide in an angularly encoded form. A first out-coupling diffractive optic formed along the first waveguide and operable to expand at least a portion of the first and second sets of image-bearing light beams and direct the expanded image-bearing light beams from the first waveguide in an angularly decoded form. A first intermediate diffractive optic formed along the first waveguide and operable to direct the second set of image-bearing light beams to the first out-coupling diffractive optic.[French]
L'invention concerne un système de guidage de lumière d'image pour transporter une image virtuelle comprenant un premier guide d'ondes et un second guide d'ondes. Une première optique diffractive de couplage formée le long du premier guide d'ondes et utilisable pour diffracter un premier ensemble de faisceaux lumineux porteurs d'image dans le premier guide d'ondes sous une forme codée angulairement. Une seconde optique diffractive de couplage formée le long du premier guide d'ondes et utilisable pour diffracter un second ensemble de faisceaux lumineux porteurs d'image dans le premier guide d'ondes sous une forme codée angulairement. Une première optique de diffraction de découplage formée le long du premier guide d'ondes et utilisable pour étendre au moins une partie des premier et second ensembles de faisceaux lumineux porteurs d'image et orienter les faisceaux lumineux porteurs d'image étendus à partir du premier guide d'ondes sous une forme décodée angulairement. Une première optique de diffraction intermédiaire formée le long du premier guide d'ondes et utilisable pour orienter le second ensemble de faisceaux lumineux porteurs d'image vers la première optique de diffraction de découplage.
