An illuminated reflex optical sighting system integrated directly into a firearm includes a lighting module comprising an illumination source mounted to a body of the firearm at a discrete first mounting location, an optical lens assembly mounted to the body of the firearm at a discrete second location spatially distanced from the first location, and a power source operably coupled to the illumination source. The illumination source is configured and operable to project a reticle onto a lens of the lens assembly for use in aiming the firearm. The illumination source and lens assembly are separately mounted to and independently removable from the body of the firearm thereby providing a low profile sighting system which substantially retains the aspects of the original firearm. The illumination source, power source, and lighting control circuitry may be housed inside the metal rear sight of the firearm in one embodiment.

An endoscope or other endoscopic instrument is provided with multiple image sensors incorporated into the distal tip, each capturing a portion of the image provided from an optical imaging system. The output from the multiple sensors is combined and manipulated into a single image of a resolution higher than is possible with only one of the sensors. The resulting image, or a portion thereof, can then be displayed to the user. A digital panning feature is also provided where the region of interest displayed from the combined field of view including data from the multiple image sensors is changed.

An IT-based astronomical telescope system includes a rotatable lens barrel having an eyepiece installed thereon; a detection device for detecting a current orientation of the lens barrel; and an image generator including a micro display provided in the lens barrel. The image generator obtains and displays the picture on the micro display. The IT-based astronomical telescope system works in a virtual reality mode, in which: the image generator is turned on, and based on the current orientation of the lens barrel detected by the detection device, obtains a picture corresponding to an optical image of stars to be imaged by the telescope system with the current orientation; and the micro display displays the picture, which is presented through the eyepiece.

A prism module includes a first prism including a first surface, a second surface and a third surface, a roof prism including a roof surface and a fourth surface, a second prism including a fifth surface, a sixth surface and a seventh surface, and a third prism including a light access surface, a first reflecting surface and a second reflecting surface. A light source is disposed above the second prism and adjacent to the first and the roof prisms. A light beam emitted by the light source enters and is reflected by the third prism, enters the second prism through the seventh surface, passes through the sixth surface, enters the first prism through the third surface, and is reflected by the second surface to leave the prism module. The light beam leaving the prism module is parallel to a baseline passing through the first, the second and the fourth surfaces.

The invention relates to a surveying instrument comprising a telescope, at least one camera providing first, second or more image signals and a controller, wherein the controller is adapted to combine the image signal data of the first, second or more image signals in order to simultaneously display at least two of the images corresponding to the first, second or more image signals on display means.

A periscope comprises an object window (4), a first reflector (5), a second reflector (6), a viewing window (7) and a display port for an electronic display (8). The first reflector (5) is arranged to reflect light from the object window (4) towards the second reflector (6). The second reflector (6) is selectively movable between a first position of use in which the second reflector (6) reflects light from the first reflector (5) towards the viewing window (7) and a second position of use in which the second reflector (6) reflects light from the display port towards the viewing window (7). The periscope provides a simple design that allows the user's view to be switched between an electronically generated image, such as night vision, and a purely optical image.

Disclosed are methods, circuits, components, apparatus, devices, assemblies and systems for imaging. According to some embodiments, there may be provided a sight for a firearm to assist in aiming the firearm towards a target in a field of view of the sight. A target view optical assembly introduces additional light information to light passing from an objective-side aperture to a viewing-side aperture. A display array assembly renders and collimates the additional light information coupled into the passing light. And a controller causes a display array of the display array assembly to dynamically render a targeting reticle, wherein a location of the dynamically rendered targeting reticle on the display is a function of a distance to an intended target.
