| Abstract: | An optic fiber interferometric system for measuring absolute distance up to 1 meter is presented. Two interferometers are employed in this system. A fiber interferometer is set up to position the target and tune the optic paths,the other is used to measure the displacement. The dynamic range of the system is expanded and the method of multiplexing the optic path by introducing the accurately calibrated optic fibers into the system is illustrated. In addition, the signal processing methods used in the system are also discussed and the initial simulation results are given in the paper. |
