PCb01 透過光偏光解析によるツイスト角及びセルギャップ測定法の検討

抄録

We propose a method to determine twist angle and gap of LC cell by observing dependence of polarization of transmitted light on orientation of LC cell. We found that glass substrates of LC cell influence determined values of twist angle and cell gap, and that 4x4 matrix approximation is needed for precise estimation of twist angle and cell gap.
