title: Cholesterol-oleate-doped polymer-dispersed liquid-crystal voltage-controlled ring projector.
abstract: We report a cholesterol-oleate-doped polymer-dispersed liquid-crystal (PDLC) device that, under laser illumination, exhibits a ring diffraction pattern, the radius of which is controlled by an externally applied voltage. This effect is accurately explained by modeling of the random distribution of spiral cells shown in the microstructure with a voltage-dependent shape variation.
