A rear adapter module for a finite conjugate optical assembly and camera is configured to couple with a core zoom module. A lens assembly of the rear adapter module includes three or more lens elements and has a positive focal length. The lens assembly exhibits a pupil size of between 16 and 25 mm and a pupil depth greater than 50 mm.

An endoscope that integrates the functions of an optical tower into a portable device, while eliminating the use of cords or cables that carry light, video signals or images, and power to the endoscope that may conflict with the movement of a surgeon and the members of the surgical team, or other operators in non-medical related applications is provided. The endoscope incorporates a camera, an image processor, a light source, a transmitter, a communication interface, a control interface, and one or more of a power source in a single portable unit or enclosure. The camera is in electrical communication with the image processor and supplies images and video to the image processor obtained via an elongated endoscope tube. The light source illuminates a viewing field of the endoscope via the elongated tube.

Increasing transparency of one or more micro-displays. A method includes attaching a transparent cover to at least a portion of a semiconductor wafer. The at least a portion of the semiconductor wafer includes the one or more micro-displays. The one or more micro-displays include one or more active silicon areas. The method further includes, after the transparent cover has been attached to the at least a portion of the semiconductor wafer, removing silicon between one or more of the active silicon areas, causing the one or more micro-displays to have a transparency of at least 50%.

A helmet accessory mount system may include a shroud configured to be coupled to a helmet and an arm assembly having a first arm configured to rotatably couple to the shroud. The system may also include an accessory interface configured to coupled to an accessory and configured to engage the arm assembly. The arm assembly may be configured to move from a deployed position to at least one storage position. The accessory may be configured to be positioned between the accessory interface and the helmet when the arm assembly is in the at least one storage position.

A modified nightvision system. The nightvision system includes an intensifier module configured to intensify received light input into the intensifier module. The intensifier module has an input side configured to receive photons of the received light and an output side configured to output intensified light resulting from the received light. The night vision system includes an added display unit proximate the output side of the intensifier module, the display unit configured to output graphical content. The night vision system includes an added beam combiner optically coupled to the display unit and the output side of the intensifier module. The beam combiner is configured to combine the intensified light and graphical content. The night vision system includes an eyepiece optically coupled to the beam combiner. The eyepiece is configured to receive the combined intensified light and graphical content and to provide the combined intensified light and graphical content to a user.

An adjustable night vision goggle adapter device includes: a mounting point configured to attach to a helmet; a body affixed to the mounting point and including a surface having a first half of a bearing/detent interface and a central axis; and an arm rotatable about the central axis, having: a first end including a second half of the bearing/detent interface and being configured to rotate about the central axis; and a second end configured to form a joint with a night vision goggle interface, wherein the joint is configured to be rotatable about a shaft and is further configured to be lockable into a fixed position holding the night vision goggle interface at a fixed angle relative to the rotatable arm.

A finite conjugate optical assembly including a core zoom module that includfes five optical groups that are configured to provide a ratio of highest to lowest magnification between 5.5:1 and 16:1. A lens attachment module and rear adapter module may be disposed, respectively, on an object side and an image side of the optical assembly. The optical assembly may exhibit an approximate etendue between 0.95 and 4.65 mm.sup.2sr, and may have a magnification of 2 or more at one or more points of the zoom. The optical assembly may be configured in accordance with between 6.6 MP and 32 MP image sensors.

A hands-free binocular device. A pair of eyeglasses has two temples. A telescopic section is mounted to each eyeglass temple. The hands-free binocular device includes lenses for magnifying images and light path redirecting devices for controlling the light path to the eyeglass lenses. Light from an image being observed flows through the magnifying lenses and is redirected by the light path redirecting device. The image is magnified and viewable by a user. The user can shift his gaze upward to view the magnified image or look down from the magnified image to view a non-magnified image. In one preferred embodiment the light path redirecting devices are prisms. In another preferred embodiment the light path redirecting devices are mirrors.

A system for displaying, on a see-through display located within a moving platform, a frame, while at least partially correcting a rolling display effect.

A mounting device having a mounting assembly for mounting a pair of goggles to a helmet is provided. The mounting assembly is configured to provide at least three degrees of freedom of movement using one or more actuation mechanisms for locking and unlocking a position of the mounting device. The number of actuation mechanisms is less than a number of degrees of freedom. In some aspects, the number of actuation mechanisms is one. A rotation base connects the mounting assembly to the helmet, and a goggle linkage connects the mounting assembly to the goggles. Various single actuation mechanisms, including a sliding mechanism, a friction-based wire/brake mechanism, and a floating friction brake mechanism, are provided.
