High Performance and Low Cost Sniper Riflescope Detection Lidar

Based on our recent progress in a proprietary Dual Source Enemy Identification and Negation Lidar (DSEINL) technology and successful Phase I feasibility demonstration, Agiltron Inc. proposes to develop a revolutionary approach to DSEINL for providing wide field of view and high detection rate to find and identify enemy combatants and sniper rifles by receiving the back or retro-reflected light from the sighting riflescope or the enemy combatant¡¦s eyes. Sighting scopes mounted on weapons, such as sniper rifles, has a reticle plate fixed in the image plane of the objective lens. The reflection off the reticle plate forms a back-propagating light beam featuring very small divergence angle and very weak depolarization. Similarly the human eye also causes a strong retro-reflection. Based on these features, Agiltron Inc. proposes to build a low cost and reliable DSEINL system using an imaging sensor to detect, identify, locate and deny enemy combatants. The proposed system uses two switching light sources that are separated a short distance 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 has already provided a proof-of-principle demonstration of this advanced detection technology and in Phase II Agiltron will produce a full specification compliant working prototype.
