We report results from a program to develop fiber-optic sensor-based instrumentation methods to allow in-situ analysis of ceramic barrier filters. The sensor was an extrinsic Fabry-Perot cavity created between ends of two longitudinally aligned fibers. Filters instrumented with these fiber sensors were tested in a combustor simulator. These tests were performed using silica optical fibers capable of withstanding the high temperature and harsh chemical environment of the combustor. The single-ended approach of the reflective Fabry-Perot sensors is well suited for thermal strain measurements. Results from several tests are presented
