Paper Abstract

Standard Michelson interferometric optical fiber sensors are used to make strain measurements on a carbon/carbon composite beam at temperatures as high as 800 degree(s)C. Copper, titanium, aluminum, and combinations of the three are investigated as sputtered end mirrors for the Michelson sensor, and it is found that the copper mirrors maintained the highest reflectivity in the 100 degree(s)C to 1000 degree(s)C temperature range. All measurements indicate that the optical fibers become more brittle with prolonged exposure to high temperatures.
