From: Uncovering different states of topological defects in schlieren textures of a nematic liquid crystal
Four regions with different cell thickness showing typical schlieren textures. Schlieren textures at the approximate thickness d of (a) 1, (b) 2, (c) 3, and (d) 4 μm. The colours arise from the interference due to the thickness dependent retardation of the NLC (5CB) with planar alignment. (Bar: 20 μm) (e) Number densities of defects with half integer and integer m at different thicknesses.
