AbstractElectromagnetic grid structures buried in optical ceramic domes may be accurately located using an electromagnetic sensing and detection techniques. Under the Phase I effort, Resodyn Corporation developed a sensor and detection technology that demonstrated position location to within 1 mil is possible. Competing technologies such as capacitive, optical, or sonic lack a key advantage the electromagnetic approach offers - optical ceramic, cutting fluids, dust, and surface conditions are electromagnetically transparent. In a manufacturing environment the sensing technology can be used to direct grinding and polishing machine operations, real-time, where to locate dome surfaces with respect to the buried grid. In a metrology environment the technology can be integrated with a coordinate measuring machine. Under the Phase II effort, Resodyn Corporation proposes to develop two useful prototypes. The first is a low-cost tabletop tool that will locate grid depth from the surface of a dome. The second is a higher cost hybrid sensor that combines the electromagnetic sensor for grid location with a laser sensor for dome surface location. The hybrid sensor could be used with a variety of manufacturing equipment.
