Abstract

With two birefringent optical fibers in series, it is possible to obtain a sensor for measuring angular positions. The resolution is better than 0.1 degree(s). This method eliminates all errors due to possible fluctuations of the power emitted by the source, as well as those due to variations of the fiber's birefringence in the range of temperatures between 0 degree(s) and 100 degree(s)C.
