A lens assembly has a pair of polarized liquid crystal lenses. Each lens has pair of parallel glass plates that are separated by upper and lower glass substrates. A series of polymer films are symmetrically spaced apart between the substrates. Both the substrates and the films are perpendicular ...

crystal lens 7 is the direction A and therefore if the linearly polarized light polarized in the direction parallel with the direction A is made incident on the lens 7, the orientation of the liquid crystal molecules is controlled by changing the voltage to be impressed to the liquid crystal ...
even if the liquid crystal molecules are radially oriented from the central part toward the peripheral part of the cell. The cell acts as a lens of the focus variable with the light polarized in all directions and there is no need for a polarizing plate. There is similarly no need for ...

[0012] In another aspect, a dynamically focused display system comprises a display configured to output circularly polarized light in a first circular polarization state. The display is disposed along an optical axis and has a forward side and a rearward side, the rearward side closer to the ...
C98RhuA crystals with p4-symmetry (one of only 10 polar crystal classes) contain an extended array of coaligned dipoles (Fig. 4) and are formally electrets: polarized dielectric materials possessing a permanent electric field44. Although electrets are metastable configurations typically manufactured ...
input to the device and controllably rotated as it passes through twisted nematic liquid crystal configuration. With no voltage applied to the electrode layers, the device causes substantially a 90 degree rotation of the polarized light10, enabling substantially all of the light to enter and pass ...
