Paper Abstract

Optical fiber force sensors using Michelson interferometer and a tunable external cavity semiconductor lase rsource are investigated in order to develop a sensor whose operating point is actively stabilized by the change of the source wavelength. Two configurations of such sensros are briefly discussed, and their advantages are compared. Based on presented results a sensor was built and tested. The sensor employs an indirect force transducer in which the force acting on it is converted into hydrostatic pressure which is subsequently measured. The sensor exhibits good linearity. Its bandwidth is currently limited by the tuning speed of the laser and can be extended by increasing the tuning speed of the laser.
