High Performance and Low Cost Sniper Riflescope Detection Lidar

Dual Source Enemy Identification and Negation Lidar (DSEINL) is a preferred method with wide field of view and high detection rate to find and identify enemy combatants and sniper rifles by receiving the co-reflected or retro-reflected light from the sighting riflescope or the enemy combatant¡¦s eyes. The sighting scope mounted on weapons, such as sniper rifles, has a reticle plate fixed on the imaging plane of the objective lens. The reflection of the reticle plate forms a back-propagating light beam featuring very small divergent angle and very weak depolarization. Similarly the human eye also causes a strong retro-reflection. Based on these features, Agiltron Inc. proposes a low cost and reliable DSEINL technology using an imaging sensor to detect, identify, locate and deny enemy combatants. The proposed technology uses two switching light sources that are separated from each other. The separation distance is adjustable, and the received images differ under the illumination by the two light sources. By subtracting the images, single or multiple riflescopes, as well as enemy combatants looking at the system can be detected while background signals can be virtually eliminated. This system holds the promise of high sensitivity, large surveillance area, low cost, high reliability and the capability of differentiating sniper rifles and human eyes from other possible strong scattering objects. This technology can be used for both pre-searching of enemy combatants and for hand off to other lethal and non-lethal systems. The Phase I effort will conduct a proof-of-principle demonstration of this advanced detection technology and in Phase II will produce a full specification compliant working prototype.
