Fiber-optic sensors, especially fiber Bragg grating (FBG) sensors are very attractive due to their numerous advantages over traditional sensors, such as light weight, high sensitivity, cost-effectiveness, immunity to electromagnetic interference, ease of multiplexing and so on. Therefore, fiber-optic sensors have been intensively studied during the last(More)
In this letter, a fiber-optic temperature sensor using an optoelectronic oscillator (OEO) has been proposed and experimentally demonstrated. Part of the fiber in the oscillator loop is taken as the sensing fiber. Since the free spectrum range of the OEO is determined by the length of the oscillator loop, and when the temperature of the sensing fiber is(More)
