Abstract

A reflectively monitored optical-fiber Fabry–Perot interferometer was embedded in a graphite–epoxy composite material. Its performance as a temperature sensor was demonstrated from 20 to 200°C. The change in relative phase shift with temperature, Δϕ/ϕΔT, was measured to be 8.0 × 10−6/°C for this embedded sensor. This value is 4% lower than for one employing a similar fiber in an air ambient. A thermal expansion coefficient for the composite material in the direction of the fiber axis is estimated from these data to be 2.1 × 10−7/°C.
