Fast, High Resolution 3-D Flash LIDAR Imager Navy SBIR FY2010.1 Sol No.: Navy SBIR FY2010.1 Topic No.: N101-083 Topic Title: Fast, High Resolution 3-D Flash LIDAR Imager Proposal No.: N101-083-1109 Firm: Arete Associates P.O. Box 2607 Winnetka, California 91396-2607 Contact: Gregory Fetzer Phone: (303) 651-6756 Web Site: www.arete.com Abstract: High-resolution lidar imaging provides fully three-dimensional images that have distinct advantages in comparison to two-dimensional images for target detection and identification. Advantages provided by the additional range information improvements in clutter removal improving detection, to lower false alarm rates due by improving identification, and to provide an additional dimension for classification. Aret� will exploit its understanding of lidar mine detection and identification coupled with its engineering expertise to develop a 3D camera designed to detect threats in the Surf Zone and Very Shallow Water. The key innovation is a novel readout integrated circuit (ROIC) design that provides higher dynamic range (>12 bits), faster sampling (<1 ns) and flexibility in range gate sampling allocation. Scaling to large numbers of pixels is enabled by low power consumption. In Phase I, the team will perform trade studies and modeling to further develop a Unit Cell that serves as the foundation for a Phase II ROIC design and development. Phase II will also comprise design of receiver optics, data acquisition control electronics, and support hardware. Successful completion will demonstrate a system concept suitable for SZ and VSW 3D imaging and detection of threats to operational maneuvers from the sea. Benefits: Successful completion of Phase I and Phase II will produce a solid state 3D camera that is suitable for the mine countermeasure systems. The constructs of the proposed receiver will result in a significant cost savings both in production and integration. Furthermore, the receiver technology will be ideally suited for other applications across a variety of DOD applications. These include UAV, UGV, and UUV lidar/ladar applications such as collision avoidance, detection, identification, and targeting. Return
