摘要： A wearable display system includes one or more emissive micro-displays, e.g., micro-LED displays. The micro-displays may be monochrome micro-displays or full-color micro-displays. The micro-displays may include arrays of light emitters. Light collimators may be utilized to narrow the angular emission profile of light emitted by the light emitters. Where a plurality of emissive micro-displays is utilized, the micro-displays may be positioned at different sides of an optical combiner, e.g., an X-cube prism which receives light rays from different micro-displays and outputs the light rays from the same face of the cube. The optical combiner directs the light to projection optics, which outputs the light to an eyepiece that relays the light to a user's eye. The eyepiece may output the light to the user's eye with different amounts of wavefront divergence, to place virtual content on different depth planes.

The optical aiming device can include a housing with a reticle pane defining a reticle display field viewable by a user and indicating a zero point, the housing further including a plurality of axially spaced lenses and defining an optical path therethrough. In various embodiments the system includes a display device configured to project an image generated from a display, a processor, and a non-transitory computer readable storage medium. The computer readable data storage medium can include instructions executable by the processor to receive a first set of ballistics input data indicating a first type of ammunition, determine a BDC pattern including at least two holdover marks corresponding to at least two ranges for the first type of ammunition, and project the BDC pattern onto the reticle display field.

摘要： A conventional head-mounted display (HMDs) can display a virtual image at a fixed focus (e.g., infinite focus). If the user looks at an object that appears closer than the virtual image, then accommodation by the user's eyes will cause the virtual image to appear blurry. The HMDs disclosed herein include a dynamic electro-active focusing element that changes the focus of the virtual image to account for accommodation by the user. This dynamic electro-active focusing element may include a curved layer of electro-active material, such as nematic or bi-stable (e.g., cholesteric) liquid crystal, disposed between a static concave mirror and a convex surface on a beam splitter or other optical element. Changing the refractive index of the electro-active material causes the focus of the dynamic electro-active focusing element, making it possible to shift the virtual image's focus in as the user's eyes change focus.
摘要翻译：传统的头戴式显示器（HMD）可以以固定焦点（例如无限焦点）显示虚拟图像。如果用户查看比虚像更近的对象，则用户眼睛的容纳会导致虚像出现模糊。本文公开的HMD包括改变虚拟图像的焦点以考虑用户的调节的动态电激励聚焦元件。该动态电活性聚焦元件可以包括设置在分束器或其他光学元件上的静态凹面镜和凸面之间的诸如向列型或双稳态（例如，胆甾醇型）液晶的电活性材料的弯曲层元件。改变电活性材料的折射率会引起动态电活性聚焦元件的焦点，从而可以随着用户的眼睛改变焦点而将虚像的焦点移动。
