Optical gyroscopes based on the Sagnac effect have been mainstay of inertial navigation in aerospace and shipping for decades. These are typically realized either as ring-laser (RLGs) or fiber-optic (FOGs). With recent rapid progress field ultrahigh-quality optical whispering-gallery mode ring microresonators, attention has focused development microresonator-based a more compact alternative to ...
Given an undamped gyroscopic system GðλÞ 1⁄4 Mλ þ CλþK with M , K symmetric and C skew-symmetric, this paper presents a real-valued spectral decomposition of GðλÞ by a real standard pair ðX;TÞ and a skew-symmetric parameter matrix S . When T is assumed to be a block diagonal matrix, the parameter matrix S has a special structure. This spectral decomposition is applied to solve the quadratic inv...
Coupling mechanisms and detection thresholds are discussed for ring laser gyroscope measurement of seismic rotation, and simultaneous records f rom a ring laser and a standard EARSS seismograph 230 km from an ML 5.3 seismic event are compared. Rotation dominates tilt and strain in modulating the Sagnac frequency, and microseisms are not significant. Power spectral densities for the ring laser a...
Although the equations' derivation in our paper published in Sensors 2011 [1] is correct, a typo has been found in the summarizing Equations (48) and (49). The dot on the B in the skew matrix should be removed. Equations (48) and (49) should be corrected as:
