我们开发了一种双频双折射光闸，它利用双折射液晶，当施加电压的频率增加时，材料的介电各向异性从正变为负。快门通过低频电压切换到透明的垂面织构，并通过高频电压切换到反射的平面织构。我们设计了一种波形，它将从垂面织构到平面织构的转变时间减少到小于100 ms。（C）1997美国物理研究所。
We developed a dual frequency cholesteric light shutter which utilizes a cholesteric liquid crystal; the dielectric anisotropy of the material changes from positive to negative when the frequency of applied voltage is increased. The shutters are switched to the transparent homeotropic texture by low frequency voltages, and switched to the reflecting planar texture by high frequency voltages. We designed a waveform which reduced the transition time from the homeotropic texture to the planar texture to less than 100 ms. (C) 1997 American Institute of Physics.
