Title (EN) METHODS AND APPARATUSES FOR REDUCING STRAY LIGHT EMISSION FROM AN EYEPIECE OF AN OPTICAL IMAGING SYSTEM
(FR) PROCÉDÉS ET APPAREILS DE RÉDUCTION D'ÉMISSION DE LUMIÈRE PARASITE D'UN OCULAIRE D'UN SYSTÈME D'IMAGERIE OPTIQUE
Abstract:
(EN) An eyepiece for a head-mounted display includes one or more first waveguides arranged to receive light from a spatial light modulator at a first edge, guide at least some of the received light to a second edge opposite the first edge, and extract at least some of the light through a face of the one or more first waveguides between the first and second edges. The eyepiece also includes a second waveguide positioned to receive light exiting the one or more first waveguides at the second edge and guide the received light to one or more light absorbers.
(FR) Selon la présente invention, un oculaire d'un visiocasque comprend au moins un premier guide d'ondes agencé de façon à recevoir de la lumière provenant d'un modulateur spatial de lumière au niveau d'un premier bord, à guider au moins une partie de la lumière reçue vers un second bord opposé au premier bord, et à extraire au moins une partie de la lumière par une face dudit premier guide d'ondes entre les premier et second bords. L'oculaire comprend également un second guide d'ondes positionné de façon à recevoir la lumière sortant dudit premier guide d'ondes au niveau du second bord et à guider la lumière reçue vers un ou plusieurs absorbeurs de lumière.
