Rapid Advanced Optical Scanner

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.
