ABSTRACT:
To determine the angular orientation of polarization axes within a length of polarization-maintaining optical fiber, a coherent light source, such as a laser, is focused onto the side of the polarization-maintaining optical fiber and a resultant scattered pattern is generated. A sensor/analyzer monitors the resultant scattered pattern and determines the location of the polarization axes.
