RESODYN CORPORATION — Department of Defense SBIR Phase I: Electromagnetic structures buried in optical ceramic domes may be accurately located using

Description

Electromagnetic structures buried in optical ceramic domes may be accurately located using an electromagnetic sensor and detection technology. A preliminary experiment demonstrated this claim but an investigation into electromagnetic properties that can vary as a result of manufacturing tolerance is required. Similar off-the-shelf technologies will be prone to error caused by these property variations. 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. This makes it possible to develop a small, light weight sensor that can integrate to a standard coordinate measuring machine or directly to a ceramic grinding and polishing machine. In a manufacturing environment, the sensing technology could be used to tell the grinding and polishing machine, real-time, where to locate dome surfaces. Resodyn Corporation proposes a Phase I study to quantify electromagnetic property variations on test specimens manufactured to tolerance limits. Using existing Resodyn Corporation technology and know-how a custom sensor will be fabricated for the study and compensation methods will be formulated.
