Abstract: A headset for augmented reality applications is provided. The headset includes at least one eyepiece configured to provide a see-through image to a user via a transparent optical component, and to provide an artificial image through a display, and a dimming shutter configured to adjust a transparency level of the transparent optical component. The dimming shutter further includes an active liquid crystal layer configured to adjust a transparency level according to an electrical power provided between two electrodes, and a photoactive layer configured to adjust the transparency level upon absorption of an ultraviolet radiation for a selected period of time. A default orientation of a host material in the active liquid crystal layer may be in a dark state or in a clear state, when no electrical power is provided. A method and a memory storing instructions to execute the method for use of the above device are also provided.

Abstract: An optical element includes a first boundary layer and a second boundary layer. A solution is disposed between the first boundary layer and the second boundary layer. The solution includes liquid crystals co-mingled with oblong photochromic dye molecules. The photochromic dye molecules are matched to the liquid crystals to offset a decrease in absorption of the photochromic dye molecules in response to a temperature increase of the photochromic dye molecules.
