Optical Frequency Domain Reflectometry (OFDR) is used to interrogate fiber sensors adhered to various structures. Temperatures in excess of 1000°C are observed on a thermal-barrier coated stainless steel test plate as it is exposed to a high-temperature torch. The surface temperature distribution is mapped with 5 mm spatial resolution at 100 Hz, revealing large spatial and temporal thermal gradients at coating defect locations. Results and response times are compared with conventional K type thermocouples. Also presented in this work, are real-time position, shape and twist measurements of a simple structure as it is subjected to various loads.
