The voltage transfer function is a rapid and visually effective method to determine the electrical response of liquid crystal (LC) systems using optical measurements. This method relies on crosspolarized intensity measurements as a function of the frequency and amplitude of the voltage applied to the device. Coupled with a mathematical model of the device it can be used to determine the device time constants and electrical properties. We validate the method using photorefractive LC cells and determine the main time constants and the voltage dropped across the layers using a simple nonlinear filter model.
电压传递函数是一种利用光学测量来确定液晶（LC）系统电响应的快速且直观有效的方法。该方法依赖于交叉偏振强度测量，它是施加到器件上电压的频率和幅度的函数。结合器件的数学模型，它可用于确定器件的时间常数和电学性质。我们使用光折变LC单元验证了该方法，并使用一个简单的非线性滤波器模型确定了主要时间常数和各层上的电压降。
