| Research Abstract |
Anomalous photoinduced current transients in the nematic phase are experimentally observed by illuminating a liquid crystal sample with a Xenon flash lamp pulse while applying a DC voltage. The mechanism has been explained theoretically by using nonlinear optical Pockel's effect induced by Freedericksz transition.
Current transient is elucidated by the effect of dc field-induced ion drift to electrodes based on an equivalent circuit. Ti is shown that the anomalous current is naturally similar to the membrane current in a living system. As an example, an optical parallel processing device using an elemental neural model is proposed for pattern recognition.
