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

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.

Gun sight

An optical hazard detection system for aircraft based on a dynamic parallax mechanism to alert the pilot of an object in the flight path by a selected amount of time in advance.

Device and method for detection of aircraft wire hazard

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.
