Paper Abstract

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.
