The Optical Properties of Polaroid for Visible Light

Polarization Imaging Screen Using Vector Gratings Fabricated by Photocrosslinkable Polymer Liquid Crystals

“…1) The light-lock system, in which the polarization of optical images play very important role, enhances the picture contrast by polarizing the light forming the image and absorbing the unexpected illuminant light by a polarizer on the screen surface. [2][3][4] In the stereoscopic 3D display system the polarization of optical images play also very important role. The stereoscopic 3D display is based on a method using polarization system to separate the left and right images with different polarization.…”

“…In the present Letter polarization imaging screen was demonstrated using vector gratings, in which the optical anisotropy is periodically rotated, fabricated by photocrosslinkable polymer liquid crystals. Unlike conventional polarizing screen consisting of dichroic polarizing films, [2][3][4] the vector gratings using photocrosslinkable polymer liquid crystals are transparent in the visible region and operate by locally modifying the polarization state of lightwaves passing through them. In result our polarizing screen consisting of vector gratings separate the left and right images with different polarization.…”
