A live-fire simulation system uses a position sensitive detector (PSD) in a weapon-mounted sensor to intercept emitted light from target emitters spatially distributed about a target. Each target emitter is modulated with a unique frequency. The system can thus not only determine the points of interception on the PSD but also determine which emitter caused which interception by using a frequency analysis.

Dynamic targeting and training system

A sight system is provided which may be selectively used in a variety of different ways. In one example, the sight system may be positioned on a rifle to provide a rifle sight system. In this example, the sight system may be positioned on the rifle barrel a substantial distance away from a user's eye. Advantageously, such an implementation may permit a user to effectively sight the rifle without compromising situational awareness. In another example, the sight system may be used to provide a telescopic sight with a reticle (e.g., a dot, crosshair, mark, or other appropriate shape) superimposed on an image (e.g., a zoomed or non-zoomed image) displayed from a camera. In another example, the sight system may be used to provide an occluded sight in which a camera and/or display of the sight system is disabled. As a result, a reticle may be displayed over an opaque background.

Sight system

Various gun sights and related methods are provided. In one embodiment, a gun sight includes a light source adapted to project light, a user-viewable interface, and an optical element. The optical element includes a first surface adapted to pass the light to provide a reticle at the user-viewable interface. The optical element also includes a second surface adapted to refract the light to provide a light guide at a peripheral area of the user-viewable interface to aid a user to substantially align the user's eye with the reticle. Various mechanisms for aligning gun sights, attaching gun sights, related methods, and other embodiments are also provided.

In this example, the sight system may be positioned on the rifle barrel a substantial distance away from a user's eye. Advantageously, such an implementation may permit a user to effectively sight the rifle without compromising situational awareness. In another example, the sight system may be used to provide a reflex sight with a reticle (e.g., a dot, crosshair, mark, or other appropriate shape) superimposed on an image (e.g., a zoomed or non-zoomed image) displayed from a camera. In another example, the sight system may be used to provide an occluded sight in which a camera and/or display of the sight system is disabled. As a result, a reticle may be displayed over an opaque background.

Various gun sights for firearms and related methods of use are provided. In one embodiment, the sight includes an apparatus adapted to be mounted at a rear end of a firearm and arranged to occlude one eye of a user of the firearm and to generate an illuminated dot that is disposed such that it is generally centered on the longitudinal axis of the barrel of the firearm. The gun sight produces a collimated beam of light that creates an image of an illuminated dot by either a refractive method or a reflective method. In use, a dominant eye of the user is occluded by the sight and the other eye of the user is focused on the target. The user then adjusts the position of the gun relative to the target such that the user perceives the illuminated dot of the sight to be positioned on the target.

In one embodiment the sight includes a dry fire detector that generates some output to the user, such as an increase in brightness of the illuminated dot, at the instant the weapon would have fired if a round had been in the chamber.

Apparatus for mounting optical sights or other weapon accessories which locates the weapon accessories (e.g. optical sights, laser range finders, night scopes, etc.) at a reduced distance relative to the position of the barrel of a weapon.

Weapon accessory mounting apparatus

A projectile tracking system for acquiring and precisely tracking a projectile in flight in order to reveal the source from which the projectile was fired. The source is revealed by the back projection of a 3-dimensional track file. The system is particularly suited for tracking a bullet fired by a sniper and identifying the location of the sniper. Projectiles of interest typically become hot due to aerodynamic heating. A telescope focuses infrared light from a relatively large field of view on to an infrared focal plane array. In a detection mode, the system searches for the infrared signature of the projectile. The telescope's field of view is steered in the azimuth by a step and stare mirror which is driven by an azimuth drive motor mounted on the frame. When a projectile is detected, the system switches to a tracking mode and the mirror is steered by the azimuth drive motor and a pivot motor to track the projectile. A laser radar system provides a laser beam which is optically coaligned with the telescope axis. Mirror angular position information, laser radar pulse travel time, and the missile spot position on detector array are used by a computer to calculate projectile trajectory information and to determine the origin of the projectile using known ballistic trajectory methods. Although only a small portion of the total trajectory may be captured, the very accurate position information permits extrapolation to determine the launch point of the projectile.

Projectile tracking system

The present invention provides a projectile tracking system for acquiring and precisely tracking a projectile in flight in order to reveal the source from which the projectile was fired. The source is revealed by the back projection of a 3-dimensional track file. The system is particularly suited for tracking a bullet fired by a sniper and identifying the location of the sniper. Projectiles of interest are typically traveling at a substantial fraction of the speed of sound or even faster than the speed of sound and therefore become hot due to aerodynamic heating. A telescope focuses infrared light from a relatively large field of view on to an infrared focal plane array. In a projectile detection mode, the system searches for the infrared signature of the fast moving projectile. The telescope's field of view is steered in the azimuth by a step and stare mirror which is driven by an azimuth drive motor mounted on the frame. When a projectile is detected the system switches to a tracking mode and the mirror is steered by the azimuth drive motor and a pivot motor to track the projectile. A short pulse high repetition rate laser in a laser radar system provides a pulsed laser beam which is optically coaligned with the telescope axis. Mirror angular position information, laser radar pulse travel time and the missile spot position on detector array are used by a computer to calculate bullet trajectory information and to determine the source or origin of the projectile using known ballistic trajectory methods. Although only a small portion of the total trajectory may be captured, the very accurate position information permits extrapolation to determine the launch point of the projectile.
