High Sensitivity, Sampling 3D LIDAR Imagers for SZ Mine Detection Navy SBIR FY2010.1 Sol No.: Navy SBIR FY2010.1 Topic No.: N101-083 Topic Title: High Sensitivity, Sampling 3D LIDAR Imagers for SZ Mine Detection Proposal No.: N101-083-1903 Firm: Voxtel Inc. 15985 NW Schendel Avenue Suite 200 Beaverton, Oregon 97006 Contact: George Williams Phone: (971) 223-5646 Web Site: www.voxtel-inc.com Abstract: For detection and neutralization of mines and other threats in the surf zone (SZ), a 3D imaging system will be developed with higher resolution and greater sensitivity than contemporary designs. Using circuits proven on existing designs, the readout integrated circuits (ROIC) of a small-pixel-size LADAR focal plane array (FPA) will be developed. The ROIC will be capable of storing 40 samples per frame, with the temporal sampling rate programmable between 1/0.5 ns and 1/10 ns. A low-noise preamplifier proven to have exceptionally high dynamic range at GHz rates is included in the pixel design. Custom circuits are included to address signal overload from glint, allowing recovery within a fraction of a frame. Features to reduce the FPA's power consumption are included. The ROIC will be designed in Phase I, and will be fabricated, integrated with detectors, and demonstrated in a LADAR camera in Phase II. Benefits: The 3D LADAR technology is designed for insertion into the Sea Shield FNC COBRA and ALMDS, but also has broad application to the wide variety of military LADAR platforms, including tactical and strategic missile seekers, autonomous navigation systems, and semi-active laser (SAL) systems. Commercial applications include robotics and automobile navigation systems. Return
