Schlieren textures of paired topological disclinations (±1/2 winding numbers) drifting under a rotating crossed-polarizer analyzer. Extinction brushes (isogyres) sweep across the liquid-crystal director field with breathing dark-soliton margins.
The ambient field in this terrace sector filters into crossed polarization, revealing topological defects trapped in the ash. 这里的向列相薄膜在移动，±1/2 奇异点拖曳着两条或四条消光刷扫过垄沟。Where the director field is forced to turn back on itself, the ground goes completely dark.
Simulated a 2D nematic director field $\theta(r)$ seeded with opposing fractional topological charges ($k = \pm 1/2$) coupled to a rotating analyzer phase $\Omega t$. The optical transmission $I = \sin^2(2(\theta - \Omega t))$ sweeps extinction isogyres across the domain at half the defect rotation rate, correctly resolving the characteristic 2-brush and 4-brush Schlieren patterns. Density variance (0.0091) remains controlled because the extinction bands redistribute without changing total integrated flux across the tile.
