Modeling of optical aberration correction using a liquid crystal device
* [email protected], Tel: (330) 672-2511 ABSTRACT Gruneisen , has shown that small, light weight, liquid crystal based devices can correct for the optical distortion caused by an imperfect primary mirror in a telescope and has discussed the efficiency of this correction. In this paper we expand on that work and propose a semianalytical approach for quantifying the efficiency of a liquid crystal bas...
متن کاملEffect of azimuthal anchoring strength on stability in a bistable chiral splay nematic liquid crystal device.
The stabilization of the metastable 180 degrees twist state in a bistable chiral splay nematic liquid crystal device is studied. The stability of the metastable 180 degrees twist state is explained using the azimuthal anchoring strength, which is a function of the twist elastic constant and the cell gap. A stable 180 degrees twist state as well as the permanent retention time can be obtained by...
متن کاملBistable bend-splay liquid crystal display
A bistable liquid crystal display based on the bend and splay configurations has been demonstrated. This display can be switched between the bend and splay deformation in a three-electrode configuration and has infinite bistable lifetime. It also has wide viewing angles, excellent contrast ratios, and very fast selection. Selection electric pulse duration of 50 ms can be used to switch this dis...
متن کاملNew bistable twisted nematic liquid crystal displays
We have developed new bistable twisted nematic ~BTN! displays that operate between the 2p/2 and 3p/2 twist states and between the p/2 and 5p/2 twist states. Together with the ~0,2p! BTN, this forms a set of all possible transmittive BTNs. Experimentally, it was confirmed that several switching wave forms could be used to switch the BTN from one state to another. Voltages below 10 V are sufficie...
متن کاملGraphene-based liquid crystal device.
Graphene is only one atom thick, optically transparent, chemically inert, and an excellent conductor. These properties seem to make this material an excellent candidate for applications in various photonic devices that require conducting but transparent thin films. In this letter, we demonstrate liquid crystal devices with electrodes made of graphene that show excellent performance with a high ...
