Chemical structure of a photo-cross-linkable copolymer liquid crystal.
Patterns of polarization modulation afforded by recording two waves.
Arrangement for recording crossed gratings. Arrows A, B, C, and D represent direction of grating vector.
The variation in the theoretical diffraction efficiencies of gratings A, B, and C with an amplitude ratio of the incident beam.
The variation in theoretical diffraction efficiencies of grating D with a phase difference between the two orthogonal components of the incident electric field.
Typical diffraction pattern obtained from crossed gratings.
Instances of polarization detection. Polarization states (a), (b), and (c) are shown in polar coordinates. Solid curves represent the analysis results, and filled plots represent the measured results obtained with the use of Glan-Thompson prisms.
