POC’s Rapid Advanced Optical Scanner (RAOS) uses laser scanning with configurable beam shaping and multiplexed, real-time image processing technologies to measure surface profiles of highly curved, highly reflective objects such as compressor airfoils and integrally bladed rotors. With an optimally configured laser projection, provided by a low-SWaP diode laser and diffractive optical element, and adaptive signal processing of images provided by multiple cameras, RAOS achieves high accuracy (better than 0.0005 in.) and system redundancy necessary for the application. Software reports out XYZ coordinates, and the point cloud output can be directly compared with a corresponding CAD model. Additional key features include wireless operation (power and data transmission) and integration with existing CMM/PMM controllers.
