Radiation-induced attenuation (RIA) in four types of polarization-maintaining optical fibers for interfer-ometric fiberoptic gyroscope (IFOG) at 1310 nm is measured. The measurements are conducted during and after...
Bias of ring-laser-gyroscope (RLG) changes with temperature in a nonlinear way. This is an important restraining factor for improving the accuracy of RLG. Considering the limitations of least-squares regression and ...
