摘要
在液晶混合光学双稳装置中,实验上观察到了由于直流电场引起的液晶中离子电荷飘移与液晶分子再取向之间竞争相互作用导致的自脉冲振荡现象。给出了该系统的弛豫方程。通过数值分析,得到了与实验定性一致的结果。
The self-oscillations in a hybrid liquid crystal optical bistable device due to the competition between the DC electric field-induced drift of ionic charge carriers and molecular reori-entation in the liquid crystal are observed experimentally. The relaxation equations of the system are given. The numerical analysis are in qualitative agreement with the experimental
results.
