Abstract
"In this thesis, the application of a coaxial cable Fabry-Perot interferometer (CCFPI) as a high temperature sensor is analyzed. Coaxial cable sensors provide the advantages of fiber optic sensors, such as the ability to be embedded and multiplexed, while overcoming the limitations created by the fragility of fibers. The fabrication process of the CCFPI, using a computer controlled drill system to create holes in the cable is discussed. By analyzing the amplitudes of the created reflections, the diameter of the holes is optimized. A new fabrication process, in which holes are drilled 180⁰ apart from each other to create a single reflection, is discussed. The effect of cable shape on the built-in reflections is tested. This is achieved by measuring the TDR of the cable while the cable is in straight, circular, and "U" shaped patterns. An analysis of the built-in reflections at different frequencies is conducted. Through the process of subjecting the CCFPI sensor to multiple heating and cooling cycles, the low sensitivity of the sensor to temperature cycling is shown. The CCFPI sensor is shown to have the same temperature sensitivity while being heated as while cooling. The high temperature performance and survivability of the CCFPI is investigated. The CCFPI sensor demonstrates an operating range of 180⁰C to 650⁰C with a linear temperature sensitivity of -108 kHz/⁰C"--Abstract, page iii.
