Abstract
A fiber optic tilt sensor is presented which can remotely sense the changes in tilt by the modulation of the light intensity. Plastic optical fibers (POF) are used in the preparation of the sensor probes. One fiber of the probe transmits the light and the other fiber receives the reflected light from the reflecting surface of the liquid filled in the sensor. The light emitting diode (L.E.D IF-E96) is used as a light source and the reflected light is detected by a simple and economical light dependent resistor (LDR). The performance of the tilt sensor has been tested with different numbers of probes and the experimental results obtained are very close to the theoretical derivations. The sensitivities for one, two and four probes are 0.029 V mrad-1, 0.060 V mrad-1 and 0.125 V mrad-1 respectively.
