Holographic Preventive Advanced Counter-Sniper Device

To address the Navy need for technology that will detect a potential sniper at a distance, Luminit, LLC proposes to develop a new Holographic Preventive Advanced Counter-Sniper (HoPACS) device based on the latest advances in holography, laser-scanning techniques, and CMOS technology. Based on the Bragg angle selectivity of shift and angle multiplexed thick transmission holograms, and the pattern imaged on a CMOS sensor as a result of illuminating the holograms with laser light, we can produce at least a 120-degree field-of-view sensor in which every hologram pair selects one particular laser beam direction thereby indicating the direction of a potential threat. This laser beam is initially irradiated by a small diode laser, scanned 360 degrees by the miniature scanner, reflected from the sniper’s optics and detected by HoPACS. Three identical sensors will cover a 360-degree field of regard in azimuth and at least 45 degrees in elevation, and will detect and neutralize a sniper with a dazzling laser before he can shoot. In Phase I, Luminit will demonstrate HoPACS feasibility by building and testing a benchtop HoPACS. In Phase II, Luminit plans to build a prototype HoPACS. The resulting system will be commercially available by the close of Phase III.
