  • Optical guide and ocular vision optical system
    Patent number: 8433172
    Abstract: The invention relates to optical guides and more precisely to guides for conveying an image without deforming the same. These guides can particularly be used in the production of ocular-vision optical systems more currently named informative spectacles. The optical guide includes an extraction section made of reflective microstructures at the surface of the guide. The microstructures define prisms having a calculated angle in order to send back the light beam at a given angle relative to the opposite surface enabling the exit thereof from the guide. Advantageously, the cut and the arrangement of said microstructures make them invisible to the eye while generating a large and comfortable image.
