在已知扭曲液晶显示器（TN-LCD）的琼斯矩阵的情况下，可以对TN-LCD的光学调制特性进行全面的预测和优化。本文提出了一种在不知道TN-LCD内部参数的情况下确定其琼斯矩阵的改进方法。与Moreno等人提出的方法相比，只需三组强度测量就可完全确定TN-LCD的琼斯矩阵，数据处理简单、稳定，并能有效地减小强度测量波动引起的计算误差。实验验证了该方法的有效性，其结果与我们确定的琼斯矩阵预测的TN-LCD的光学调制特性相吻合。
The optical modulation properties of twisted-nematic liquid-crystal display (TN-LCD) can be totally predicted and optimized when its Jones matrix is known. An improved method for determining the Jones matrix of the TN-LCD without knowing its internal parameters is presented in this paper. Only three sets of intensity measurements are needed for the complete determination of the TN-LCD’s Jones matrix for a single wavelength, much less than the procedure offered by Moreno et al. This method is easier and stable in data processing and capable of diminishing the calculation error resulting from the fluctuation of intensity measurement effectively. The validity of this method is verified experimentally, whose results coincide well with the optical modulation properties of the TN-LCD predicted by our determined Jones matrix.
