利用微研磨工艺制作了一种由三个液晶分子取向畴组成的二维液晶光栅，并将其应用于斯托克斯偏振测量。发现所获得的LC分子取向状态中的面内取向方向、延迟和扭转角在空间中变化。制作的LC光栅应用于斯托克斯偏振测量，以确保所提出的测量方案的可行性。实验结果表明，所测得的入射光的斯托克斯参数与实际入射光的斯托克斯参数基本一致。此外，我们指出的可能性的性能可调的施加电压，这可能是一个很大的优势，LC光栅斯托克斯偏振。
A two-dimensional (2D) liquid-crystal (LC) grating consisting of three LC molecular orientation domains is fabricated by a microrubbing process, with the aim of application to the Stokes polarimetry. It was found that the in-plane orientation direction, retardation, and twist angle in the obtained LC molecular orientation state varied in space. The fabricated LC grating was applied to the Stokes polarimetry to ensure the viability of the proposed measurement scheme. As a result, the measured Stokes parameter of the incident light agreed with that of the incident light. Furthermore, we point out the possibility of performance adjustability by an applied voltage, which can be a great advantage of the LCgrating Stokes polarimetry.
