A virtual image display apparatus includes a display device serving as an image forming unit, an image optical system including a first mirror member serving as an outer mirror member and receiving imaging light from the display device, and a partially reflecting type mirror portion reflecting imaging light emitted from the image optical system toward a position of an exit pupil. The first mirror member serving as the outer mirror member and the partially reflecting type mirror portion are integrated.

A method may include stretching a deformable bounding element into a stretched state. The method may further include coating the deformable bounding element with at least one layer of an anti-reflective material while the deformable bounding element is in the stretched state and assembling an optical lens assembly including the deformable bounding element, such that the optical lens assembly adjusts at least one optical property by controlling a shape of the deformable bounding element. The deformable bounding element may have less tension when in a neutral state than the deformable bounding element has when in the stretched state. The method may additionally include coating the deformable bounding element with at least one layer of an anti-reflective material while the deformable bounding element is not in a stretched state. Various other apparatuses, systems, and methods are also disclosed.

A mirror device includes a frame body, a shaft member provided inside the frame body and connected to the frame body, and a reflection member fixed to the shaft member and provided so as to be capable of swinging around an axis of the shaft member. The reflection member has a base portion provided along an axial direction of the shaft member and a reflection portion provided on the base portion. The base portion has a three-dimensional uneven structure including a bottom wall portion having a main surface provided along the axial direction of the shaft member and a plurality of side wall portions extending from the bottom wall portion opposite to the reflection portion.

An optical system for a head-worn computer includes an upper optical module adapted to convert illumination into image light by illuminating a reflective display through a field lens, wherein the image light is transmitted back through the field lens, then through a partially reflective partially transmissive surface and into a lower optic module adapted to present the image light to an eye of a user wearing the head-worn computer and the upper optical module being positioned within a housing for the head-worn computer and having a height of less than 24 mm, as measured from the reflective display to the bottom edge of the rotationally curved partial mirror.

A display apparatus includes a frame 10, a right-eye image display apparatus 20R, and a left-eye image display apparatus 20L, each of the image display apparatuses including an image forming apparatus 30 and an optical apparatus 40, the optical apparatus 40 including a light guiding plate 41, a first deflection mechanism 42, and a second deflection mechanism 43, in which an image coming from the image forming apparatus 30 enters the first deflection mechanism 42, is deflected by the first deflection mechanism 42, is guided through the light guiding plate 41, enters the second deflection mechanism 43, is deflected by the second deflection mechanism 43, and enters a pupil 51 of an observer 50; and an image that is formed by the right-eye image display apparatus 20R and an image that is formed by the left-eye image display apparatus 20L are not fused with each other.

A method includes projecting a single color illumination light having a first color on a liquid crystal on silicon display device, thereby obtaining a single color image light having the first color from the liquid crystal on silicon display device. The method also includes receiving image light having at least a second color that is different from the first color from a display panel that is different from a liquid crystal on silicon display device and combining the single color image light and the image light for projection toward an eye.

Described is a wide field of view, high resolution digital night vision system that uses transparent, repositionable eyepieces to present night vision information in the field of view of the user. The WNVS is advantageous in that it can be used in both night environments, but also in daytime environments by using clear eye pieces that allow the user to concurrently see the outside environment or allowing the eyepieces to be positioned out of the field of view of the user without significantly occluding the user's field of use during daytime use.

A head-mounted display includes a main body having a housing defining at least a portion of an exterior of the head mounted display; a built-in display disposed in the housing; a wearing band extending from the main body to a rear side and having a shape enclosing a head of a user as a whole; a right-side extending section configured to make up a right-side part of the wearing band; a left-side extending section configured to make up a left-side part of the wearing band; and a frame which is separate from the housing and constitutes at least a portion of a rear part of the main body, where the frame has left and right openings for receiving left and right lenses, respectively, and a recessed section for accommodating a user's nose when the head-mounted display is worn.

A head-mounted display configured to enhance the ease of wearing work and the stability of wearing is provided. A wearing band has an extending section and a movable section that is movable relative to the extending section in the length direction of the wearing band.

An artificial-reality headset assembly includes an artificial-reality headset, a battery pack, and a plurality of head straps. One end of each of the head straps is coupled to the artificial-reality headset and the respective opposite end is coupled to the battery pack. The plurality of head straps includes one or more side straps configured to be worn around a user's head. The battery pack is located in proximity to a posterior portion of the user's head when the artificial-reality headset is worn. The position and weight of the battery pack function to counterbalance weight of the artificial-reality headset, creating a symmetric balance along an axis of the user's head and maintaining the position of the battery pack regardless of adjustment to the one or more side straps. In some embodiments, the plurality of head straps includes an overhead strap (e.g., an adjustable ergonomic strap).
