Abstract

The invention relates to anti-dazzle devices for both polarized and non-polarized radiation. The technical result consists in the production of an effective anti-dazzle filter that exhibits minimal losses and adapts to dazzling radiation sources. The filter comprises optically transparent systems using an optically transparent dielectric substance and a birefringent substance on liquid crystal molecules, said systems being designed and arranged in the same way and diminishing the intensity of the radiation transmitted therethrough. The position of the electrodes on the surfaces of each system is different. The surfaces of the dielectric substance contain an orientator which aligns the major axes of the molecules of the birefringent substance with the corresponding polarization component of the transmitted radiation so that the conditions of dispersion and/or reflection are met for one or both polarization components of the radiation. The refractive indices of the birefringent substance are close to the refractive indices of the dielectric substance when the major axes of the liquid crystal molecules are positioned along the direction of the incident radiation, and differ for one of the orthogonal polarization components when the position of the major axes of the liquid crystal molecules changes in a direction set by the orientator. The molecules of the birefringent substance change orientation when the intensity of the radiation exceeds a given threshold.
