  • Optical polarisation device for a stereoscopic image projector
    Patent number: 9740017
    Abstract: An optical polarization device for a stereoscopic image projector, including: a polarizer optical element including two beam splitter-polarizer plates, joined to one another; first and second optical reflectors configured to modify, respectively, a trajectory of first and second light beams reflected such that the reflected and transmitted light beams are projected to form one and same stereoscopic image; first, second, and third polarization modulators configured to selectively switch the optical polarization, respectively, of a transmitted light beam, of the first and of the second reflected light beams, between the first and second states of optical polarization; and a control circuit for the polarization modulators.
    Type: Grant
