项目摘要

1.The polarization states of reflected light intensities of the reflective LC cell are measured and the normalized Stokes parameters of the light transmitted through the LC cell are obtained using Stokes parameter equations. Then, the cell parameters such as the cell thickness, twist angle and pretilt angle in reflective liquid crystal (LC) cells can be deter-mined simultaneously by using these Stokes parameters.2.The cell thickness distribution can easily be determined by measuring the Stokes parameters at one wavelength, and both of the cell thickness and twist. angle can also be determined by using two wavelengths, where the twist angle and/or the pretilt angle are assumed to be the designed values. Furthermore, Three cell parameters including the pretilt angle as well as the cell thickness and twist angle can also be measured by using three wavelengths Stokes parameter equations.3.Two-dimensional LC cell parameters such as the cell thickness, twist angle and pretilt angle of the reflective LC cell can easily be obtained and their mapping results are successfully demonstrated.4.The cell parameters in the practical LC display panel with the color filters such as a red, green and blue (RGB) can be determined by measuring Stokes parameters at the wavelength of near-infrared region.5.The results are examined and the research work is summarized.
1.测量了反射式液晶盒的反射光强度的偏振态,并利用斯托克斯参数方程得到了透射过液晶盒的光的归一化斯托克斯参数。利用这些斯托克斯参数,可以同时确定反射式液晶盒的盒厚、扭曲角和预倾角等盒参数。2.通过测量一个波长下的斯托克斯参数,以及盒厚和扭曲角的斯托克斯参数,可以很容易地确定盒厚分布。也可以通过使用两个波长来确定扭转角,其中假定扭转角和/或预倾角为设计值。此外,利用三波长Stokes参数方程还可以测量液晶盒的预倾角、厚度和扭转角等三个液晶盒参数。3.二维液晶盒参数,如液晶盒厚度、液晶盒厚度、液晶盒扭转角等。4.通过对实际液晶显示屏的液晶盒参数的计算,得到了液晶盒的扭转角和预倾角,并成功地验证了它们的映射结果。通过测量近红外波段的斯托克斯参量,可以确定红、绿色和蓝色(RGB)等彩色滤光片。
