Abstract :
An optical fiber curvature sensor is fabricated by using a short section of polarization maintaining fibre as the sensing component spliced in a Sagnac loop. The sensitivity of the curvature measurement of 0.0344 m-1/pm is achieved experimentally. The propose sensor is simple and cheaper than that of photonic crystal fiber.
