Measurement accuracy improvement with PZT scanning for detection of DPC in Hi-Bi fibers
29 July 2002/Vol. 10, No.15/OPTICS EXPRESS，-0001，（）：
Piezo-electronic transducer is used in combination with mechanical scanning devices to improve measurement accuracy in a distributed polarization coupling detection system. For mechanical scanning range of 150mm with 200-nm resolution, the measurement error of polarization-coupling intensity can be improved from 38% to 2% in combination with a 20-nm resolution piezo-electronic transducer.
