WebJul 25, 2008 · However, the Shupe formula does not describe the effect of homogeneous, but transient heating of the fiber coil, which leads to an inhomogeneous deformation of the fibers and thus to nonreciprocity. Furthermore, the effect of inertial forces such as vibrations has been described first in the work of Mohr and Schadt (2004) and shall be extended in … http://kpubs.org/article/articleMain.kpubs?articleANo=E1OSAB_2011_v15n3_237 WebSep 12, 2007 · We report a detailed experimental and theoretical analysis of a novel type of fibre-optic gyroscope (FOG) that utilizes an air-core photonic-bandgap fibre (PBF) in its sensing coil. The anticipated benefits of using an air-core fibre include dramatically reduced phase bias drift due to temperature (Shupe effect), magnetic field (Faraday effect ... bishop and skinner boat insurance
