Dual frequency and nematic LC materials were reported to be used in astronomical observations. However  nematic LC with its simple producing and driving method and multi-gray-level is promising in the application. We have investigated the nematic LC AO system and promoted its application for nearly ten years. Here  we reported our newest nematic LC AO system with bandwidth result of 3dB is 54.4 Hz  0dB bandwidth is 79.1Hz. 2012 IEEE.   Electric-field-induced effective anchoring energy in nematic liquid crystal (EI CONFERENCE) 会议论文  OAI收割 2010 International Conference on Display and Photonics, July 12, 2010 - July 13, 2010, Nanjing, China Ye W.; Zhang Z.; Xing H.; Yang G.; Chen G. 收藏  |  浏览/下载：20/0  |  提交时间：2013/03/25 Electric-field-induced effective anchoring energy in nematic liquid crystal is investigated taking surface and flexoelectric polarization into consideration. The analytical expressions of effective anchoring energy for both bottom and upper substrate  containing these two polarizations  are derived. The effective anchoring strength for both bottom and upper substrate is also obtained by means of a systematic method  which is relevant to magnitude of two polarizations and determined by the applied voltage U. Applying the obtained expressions into an original weak anchoring hybrid aligned nematic cell  the effective anchoring strength are determined with the different magnitudes of two polarizations and the different applied voltage U.   Molecular dynamics simulation of the rotational viscosity and its odd-even effect of nematic liquid crystals ncb(4-n-alkyl-4 '-cyanobiphenyls, n=5-8) 期刊论文  iSwitch采集 Acta physica sinica, 2009, 卷号: 58, 期号: 8, 页码: 5560-5566 作者:  Zhang Ran;  He Jun;  Peng Zeng-Hui;  Xuan Li 收藏  |  浏览/下载：29/0  |  提交时间：2019/05/10 Rotational viscosity  Odd-even effect  Molecular dynamics simulation  Nematic liquid crystal   The cell thickness and twist angle measurement of twist nematic liquid crystal cell by rotation of a quarter-wave plate using fourier analysis method (EI CONFERENCE) 会议论文  OAI收割 Asia Display 2007, AD'07, March 12, 2007 - March 16, 2007, Shanghai, China Cui H.-Q.; Ling Z.-H. 收藏  |  浏览/下载：25/0  |  提交时间：2013/03/25 Proposed a new method of determining the cell thickness and the twist angle of twisted nematic liquid crystal cells  a quarter-wave plate was inserted between the liquid crystal cell and the analyzer  a stepper motor rotated the Retarder by 360  and measured the light intensity of every modulated point  solved the stokes parameters of polarization light exiting from the liquid crystal cell using Fourier analysis method  thereby determining the cell thickness and the twist angle. Experiments indicated that it is suitable for measuring the low-cell-gap accurately. In addition  it also can be applied to the measurement of the cell thickness and twist angle of single polarizer reflected liquid crystal cell.   Theoretical research of an improved C-V method to measure the elastic constants of nematic liquid crystal (EI CONFERENCE) 会议论文  OAI收割 Asia Display 2007, AD'07, March 12, 2007 - March 16, 2007, Shanghai, China Kong X.; Jin H.; Huang X.; Liao Y.; Liu J. e. 收藏  |  浏览/下载：21/0  |  提交时间：2013/03/25 A more exactitude C-V method to determine the elastic constants for nematic liquid crystal is discussed. For positive nematic liquid crystal(NLC)  the threshold voltage becomes uncertain when the pretilt angle is not zero  so the value of k11 must be erroneous. To solve this problem  we report the formulas about capacitance and voltage with the pretilt angle isn't zero  present the method to determine the elastic constants -k11 and k 33 simultaneously by curvefitting. We simulate and analyze the theory of this method in virtue of MatLab. The proposed method can reduce the requirement of LC cell  increase the accuracy.
