The phase of the output voltage is the same as the phase of the voltage of the signal winding having the greatest amplitude. Hence the output voltage either lags or leads the input voltage by 90°, depending on the direction of displacement of the sensing element (bob) with respect to the...
Therefore it has such merits that the performance is not affected by a supporting method, that the agreement between the excitation frequency and the vibration frequency necessary for a wide detection amplitude can be realized easily without expecting too much of the machining/assembly precision, thus...
However, vibration amplitude of the adhesives 2, 4 are significantly reduced by an action of the thin part 51 in a spring structure. When vibrating stress applied on the adhesives 2, 4 is small, deformation (amplitude) of the adhesives 2, 4 is small. Thus, even when there is hysteresis ...
This article focuses on a hemispherical resonator gyro driven by the Coriolis effect. A hemispherical shell, called a resonator, is maintained in the resonance state by amplitude control and phase locking control. Parametric excitation has been used to control the amplitude. For rate measurement mode...
the standard error is over 0.0337 dBm,and the displacement extent of the prism is higher than 53%of the radius of the beam waist in the gyro cavity,the amplitude modulation extent of gyro output signal can reach up to 16%,which badly influences the measurement accuracy of the laser gyro....
A laser gyro system is disclosed wherein the lock-in error associated with the sensor signal deriving phase information of the phase relationship between a pair of lasing beams therein is accounted for and utilized for correction and/or control. Inventors...

So the D term calculation requires an LPF to stop the delta D value getting higher and higher as frequency of noise goes up and up (even if the amplitude does not change). Boris has a solution that I think is very effective and necessary with his PT1 code. With this code I think ...
A monolithic single crystal Si rate-gyro consisting of in the preferred embodiment, an outer torsional frame, self resonating with a substantial amplitude, as controlled by a four-terminal piezo torsion sensor, connected to an inner fram... Armand P. Neukermans,Timothy G. Slater - US 被引量...
In resonator fiber optic gyroscopes by digital modulation, imperfect serrodyne′s reset amplitude V_ 2π has influence on the rotation sensing errors and the scal. 谐振式光纤陀螺 (R- FOG)是采用环形谐振腔来增强 Sagnac效应的 ,其检测方案可以分为开环和闭环 ,在电路实现上 ,根据相位调制器控制信号...
