Optical device with photochromic material and electrically dimmable element for augmented reality applications

A head-mounted device for augmented reality applications is provided. The head-mounted device includes at least one eyepiece configured to provide a see-through image to a user via a transparent optical component and 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 power supplied between the two electrodes; and a photosensitive layer configured to adjust the transparency level upon absorption of ultraviolet radiation for a selected period of time. The default orientation of the host material in the active liquid crystal layer may be in a dark state or a bright state when no power is provided. A method and memory storing instructions for performing a method using the above device are also provided. 提供了一种用于增强现实应用的头戴式设备。该头戴式设备包括至少一个目镜和调光快门，该至少一个目镜被配置为经由透明光学部件向用户提供透视图像并且通过显示器提供人工图像，该调光快门被配置为调节该透明光学部件的
