Next-Generation Semi-Active Laser (SAL) and Miniature Designator

ABSTRACT:A novel next-generation (Next Gen) semi-active laser (SAL) seeker will be developed, which includes a novel gun-hardened miniature eye-safe laser designator, ideal for weapon and UAV mounting. The laser will optionally be configured with a laser positioning and timing (PAT) imager, which can be used to aid target handover and to provide active feedback for beam stabilization. The SAL seeker will be configured with a wide-field of view optic, and with an integral diffuser, which provides superior laser spot-detection capabilities. The seeker will also include a new class of focal-plane array, which allows for simultaneous acquisition and identification of a large number of laser pulse repetition frequency (PRF) codes. In Phase I, each of the components will be demonstrated, alone and configured into a proof-of-concept prototype. The performance will be used to update system models, which will be used to configure a robust system to be fabricated and demonstrated in Phase II.BENEFIT:The eye-safe laser detection, locating, and pulse-processing technology will be used commercially in a number of applications, including 3D site and building surveys, land mapping, rangefinding, 3D imaging, gesture recognition, and automotive collision avoidance and driver-assistance systems, as well as free-space optical communications systems.
