Claim 0:
1. A remote temperature measurement system comprising:
a control system;
an optical emitter/receiver in communication with the control system; and
a probe system comprising a resonant probe embedded within a component of a gas turbine engine, an optical port on a surface of the component and in optical communication with the optical emitter/receiver, and a waveguide optically connecting the resonant probe to the optical port, whereby an optic signal emitted by the optical emitter/receiver passes through the optical port and the waveguide to the resonant probe, and a reflected optical signal travels from the resonant probe through the waveguide and the optical port back to the optical emitter/receiver, and wherein the control system is configured to determine a local temperature of the component from the reflected optical signal.
