Descrição: A method to capture ordered and disordered regions in reactive mesogen films to take advantage of the anisotropic thermal properties and fabricate a thermally responsive patterned film is presented. The image shows white‐light interferometer images of isotropic cylinders in cholesteric material. The underlying principle phenomenon observed here is well described by a finite‐element simulation.
