Patent number: 8896675Abstract: The present invention relates to a display system for stereoscopic viewing, the system comprising a binocular viewing device, information content, and a display source. The display system is remarkable in that it further comprises electronic components for implementing pieces of software for optimizing the binocular viewing device, the information content, and the display source, said pieces of optimization software together forming a loop for managing various parameters. The wearer of said device can thus view the information content via the binocular viewing device under conditions that are best adapted to the wearer's physiology.Type: GrantFiled: April 10, 2007Date of Patent: November 25, 2014Assignee: Essilor International (Compagnie Generale d'Optique)Inventors: Cédric Buchon, Benjamin Rousseau, Sarah Marie, Cécile Bonafos

Patent number: 8820919Abstract: The invention provides an adjustment method for adjusting a binocular display, the display comprising for each eye of the wearer, an optical imager for shaping light beams corresponding to an image emitted by a beam generator device and for directing them towards each of the wearer's eyes so as to enable information content contained in a virtual image to be viewed, the display being associated with a pair of eyeglasses having two lenses supported by a frame. According to the invention, the method consists in moving at least one said lens (10A, 10B) relative to said frame (11) with three degrees of freedom, in order to obtain superposition of the two virtual images, each said imager being contained in said lens (10A, 10B) of said pair of eyeglasses.Type: GrantFiled: June 9, 2010Date of Patent: September 2, 2014Assignee: Essilor International (Compagnie Generale d'OptiqueInventors: Bertrand Billon, Cédric Buchon, Vincent Roptin

Patent number: 8116001Abstract: A light pipe is provided for transmitting light signals from one of its ends to its other end facing toward the eye of a user for viewing a virtual image. The light pipe includes a diffractive component formed directly in the inlet surface. The diffractive component is an element satisfying the equation of an aspherical component of revolution of the “kinoform” type, where the diffractive component of the pipe has power situated in a range D (Thresh, X) defined by D(Thresh, X)=DOPTDIF(Thresh) INTERSECTION DXT(X).Type: GrantFiled: June 14, 2007Date of Patent: February 14, 2012Assignee: Essilor International (Compagnie Generale d'Optique)Inventors: Renaud Moliton, Cécile Bonafos, legal representative, Cédric Buchon
