摘要
利用Pspice等效电路模型,模拟了入射光波长、温度以及激励电压频率等典型参量对铁电液晶光电响应速度的控制作用 模拟结果表明,在可见光范围内,响应速度随波长的增加而减慢;温度参量则存在一个拐点,响应速度在该点达到极小值;同时,激励电压存在一个上界频率,当频率参量取值超过界值时会对响应速度产生较大影响.
In order to analyze different performances of a ferroelectric liquid crystal (FLC) layer when it works in different conditions, an electronic model in Pspice is presented. Using this equivalent circuit, it is easy to simulate and analyze how a FLC layer behaves in different temperatures, different wavelengths of incident lights and different frequencies of drive voltage. According to the simulation, when wavelength changes within the range of visible lights, the response velocity drops as wavelength increases. As to the parameter of temperature, the velocity reaches its lowest when temperature gets to a certain degree. Meanwhile, the response velocity is greatly influenced by the frequency of drive voltage only when it is beyond its critical value. The result corresponds well with the reports of previous articles.
