A simple nonuniform irradiation method based on the laser speckle pattern is applied to produce meso-scale domain structures composed of liquid crystal and reactive mesogen phases. Effect of laser speckle pattern irradiation on formation of temperature dependent polymer dispersed liquid crystal is investigated by using spectroscopic measurements.
