Rapid Advanced Optical Scanner Navy SBIR FY2015.1 Sol No.: Navy SBIR FY2015.1 Topic No.: N151-017 Topic Title: Rapid Advanced Optical Scanner Proposal No.: N151-017-0453 Firm: Physical Optics Corporation 1845 West 205th Street Torrance, California 90501-1510 Contact: Jae Choi Phone: (310) 320-3088 Web Site: www.poc.com Abstract: To address the Navy's need for a rapid and reliable measurement technology for high-curvature surfaces such as compressor airfoils, Physical Optics Corporation (POC) proposes to develop a new Rapid Advanced Optical Scanner (RAOS). This proposed scanner solution is based on a new optical module design with multiple cameras inspecting surfaces illuminated by a sharp, line-shaped laser beam. The RAOS employs efficient image processing software and 3D point-cloud analysis algorithms that POC has developed for related metrology systems. Specifically, the innovation in the optical module design and image processing will enable the RAOS system to inspect high-curvature surfaces with polished finishes. As a result, the system will rapidly and reliably inspect parts with complicated geometry and high-curvature surfaces, such as compressor airfoils and other integrally bladed rotors, which directly addresses the system requirements. In Phase I, POC will demonstrate the feasibility of the RAOS technology by performing profile measurements using RAOS on test samples with highly curved surfaces, achieving technology readiness level (TRL)-4. In Phase II, POC plans to enhance, optimize, and ruggedize the RAOS technology to meet all of the Navy's requirements and reach TRL-7. Benefits: POC anticipates that the RAOS technology will apply to a tremendous range of applications in precision machining and inspection. Highly curved, highly reflective surfaces exist in many critical components (engines, rotors, etc.) in the aerospace and automobile industries, and the use of rapid non-contact metrology systems will continue to grow. Development of a non-contact metrology system for these applications will increase the production efficiency in many industries. Return
