Novel, Multi-Use Diode Laser-Based Sensor for Remotely Piloted Aircraft

ABSTRACT: In this Phase I SBIR proposal Physical Sciences Inc. (PSI) outlines the development of a scaleable, multi-use laser sensor with size, weight and power (SWaP) characteristics that are compatible with small, remotely piloted aircraft (RPA). PSI"s approach will result in a modular sensor that can be scaled to the requirements of a specific RPA and mission. Current range finder and designator technology based upon Q-switched solid state lasers is not compatible with the SWaP of small RPAs. PSI"s approach is to develop scalable source and optical system designs to meet the laser sensor specifications. In Phase I, PSI will develop a prototype design for the laser sensor that is compatible with a range of small RPAs. The design process will include: 1) laser source characterization and selection, 2) optical system design, 3) modeling of receiver signal levels for various mission scenarios to determine the optimum receiver characteristics and 4) preliminary design of a prototype laser design incorporating the laser source, optical system and receiver system characteristics. In Phase II the prototype will be built and tested, both in the laboratory and in the field. BENEFIT: The proposed laser sensor technology will provide the Air Force with unique laser sensors that can be applied to a broad range of RPA platforms to significantly improve their existing sensor capabilities. The compact, efficient characteristics of the technology will also benefit the development of lightweight laser rangefinders and designators that are used in other military and commercial applications.
