A targeting system for visualizing a target includes a targeting assembly having a main body mountable to a weapon and a rail-locking member selectively mountable to the main body. The main body supports at least one of a visual assembly, a power assembly, and a transmission assembly. Communicating with the targeting assembly is a viewing assembly.

A wearable device that aids vision of a person is disclosed that includes a display system including a display device, a first polarizer parallel to the display device, a quarter waveplate, and a mirror. The display device, the first polarizer, the quarter waveplate, and the mirror are arranged sequentially such that the display device is disposed at a first end of the display system and the mirror is disposed at a second, opposite end of the display system. The display system has a length corresponding to a focal length of the mirror. A camera system includes a camera and an image stabilization system with a zoom magnification configured to provide up to at or about 60 times zoom. The display system and the camera system are secured to a mount and are movable relative to each other about the mount. The mount is secured to a frame.

An optical instrument, such as a spotting scope, is provided. The optical instrument may include a range finder configured to calculate or otherwise determine a distance between the optical instrument and an identified object. The optical instrument may also include a display and a user interface. In some embodiments, an operation system associated with the optical instrument may include sensing touchless gestures. For example, hand gestures or eye gestures may be used to navigate a user interface, to actuate the laser range finder, to alter the brightness of a display, or to carry out any of a number of other operational commands.

An inter-pupillary distance (IPD) adjustment mechanism for a head-mounted display (HMD) is disclosed. The IPD adjustment mechanism is coupled to a structural plate of the HMD and to an eyecup for each eye that includes a lens and display assemblies. The IPD adjustment mechanism includes an arm for each optical assembly, and a gear that interfaces with the arms. In one embodiment, each arm is a rack gear that interfaces with a pinion gear. The eyecups are each mounted on one or more rails that allow for the eyecups to adjust a distance between the eyecups along a single dimension. Accordingly, movement of the gear causes both eyecups to move either away from or towards each other. In some embodiments, the IPD adjustment mechanisms is driven by a motor. In some embodiments, the IPD adjustment mechanism is manually controlled by the user.

Augmented reality systems and methods for automatically repositioning a virtual object with respect to a destination object in a three-dimensional (3D) environment of a user are disclosed. The systems and methods can automatically attach the target virtual object to the destination object and re-orient the target virtual object based on the affordances of the virtual object or the destination object. The systems and methods can also track the movement of a user and detach the virtual object from the destination object when the user's movement passes a threshold condition.

This disclosure describes a head-mounted display with a display assembly configured to display content to most or all of a user's field of view. The display assembly can be configured to display content in far-peripheral regions of the user's field of view differently than content upon which a user can focus. For example, spatial resolution, color resolution, refresh rate and intensity (i.e. brightness) can be adjusted to save resources and/or to bring attention to virtual content positioned within a far-peripheral region. In some embodiments, these changes can save processing resources without detracting from the user's overall experience.

A panel mask(s) rendered on a display panel(s) of a head-mounted display (HMD) may be dynamically adjusted (increased and decreased) in size in order to hide unwanted visual artifacts from view, as needed. For example, if frames are being rendered on the display panel of the HMD using re-projection, a size value associated with at least a portion of the panel mask can be adjusted based on rotation of the HMD to increase or decrease a size of at least the portion of the panel mask from a current size to an adjusted size, and the panel mask can be rendered with at least the portion of the panel mask rendered at the adjusted size to hide the unwanted visual artifacts. The size of the portion of the panel mask can subsequently decrease, over a period of time, if re-projection ceases and/or if head rotation ceases or slows down.

An optical lens barrel having a transmissive liquid crystal display function, liquid crystal display module and display screen, wherein the optical lens barrel comprises a lens barrel body, an eye lens disposed at one end of the lens barrel body, an objective lens disposed at the other end of the lens barrel body, and an LCD display screen disposed at a focal plane position of the optical lens barrel, wherein the LCD display screen is a light scattering LCD display screen; the optical lens barrel is further internally provided with a visible light source; the position of the light source should satisfy: the light source is disposed outside a visible area of the light scattering LCD display screen.

Systems and devices can include a first optical element and a second optical element, the first and second optical elements transparent to visible light; and a photovoltaic element residing between the first optical element and the second optical element, the photovoltaic element transparent to visible light, the photovoltaic element to generate electricity based on the absorption of ultraviolet (UV) and near-infrared (NIR) light. The photovoltaic element can include a conductive element to conduct electricity generated from the absorption of UV and NIR light.
