    Abstract: A head-mounted display may include a display system and an optical system in a housing. The display system may have displays that produce images. Positioners may be used to move the displays relative to the eye positions of a user's eyes. An adjustable optical system may include tunable lenses such as tunable cylindrical liquid crystal lenses. The displays may be viewed through the lenses when the user's eyes are at the eye positions. A sensor may be incorporated into the head-mounted display to measure refractive errors in the user's eyes. The sensor may include waveguides and volume holograms, and a camera for gathering light that has reflected from the retinas of the user's eyes. Viewing comfort may be enhanced by adjusting display positions relative to the eye positions and/or by adjusting lens settings based on the content being presented on the display and/or measured refractive errors.

    Abstract: A head-mounted display may include a display system and an optical system in a housing. The display system may have a pixel array that produces light associated with images. The display system may also have a linear polarizer through which light from the pixel array passes and a quarter wave plate through which the light passes after passing through the quarter wave plate. The optical system may be a catadioptric optical system having one or more lens elements. The lens elements may include a plano-convex lens and a plano-concave lens. A partially reflective mirror may be formed on a convex surface of the plano-convex lens. A reflective polarizer may be formed on the planar surface of the plano-convex lens or the concave surface of the plano-concave lens. An additional quarter wave plate may be located between the reflective polarizer and the partially reflective mirror.

    Abstract translation: 头戴式显示器可以在外壳中包括显示系统和光学系统。 显示系统可以具有产生与图像相关联的光的像素阵列。 显示系统还可以具有来自像素阵列的光通过的线性偏振器和通过四分之一波片后光通过的四分之一波片。 该光学系统可以是具有一个或多个透镜元件的折反射光学系统。 透镜元件可以包括平凸透镜和平凹透镜。 部分反射镜可以形成在平凸透镜的凸表面上。 可以在平凸透镜的平面上或平凹透镜的凹面上形成反射偏振片。 额外的四分之一波片可能位于反射偏振片和部分反射镜之间。
