From: Spontaneous light-induced Turing patterns in a dye-doped twisted nematic layer
Stripe domain induced by photo-isomerization in a dye-doped twisted nematic liquid crystal cell between polarizers P1 and P2 with different relative angles. The upper and bottom panels, respectively, account for the observed snapshots and schematic configuration of the polarizers and liquid crystal sample. (a) Both polarizer are parallel, the relative angle between polarizers is 0°, (b) the relative angle between polarizers is 45°, and (c) both polarizers are crossed, that is, the relative angle between polarizers is 90°.
