Fiber optic gyroscope and method for removal of dead band error

摘要

"Gyroscope, optical fiber and method for removing error of dead band".It is provided a controller of the magnitude and timing of the jump phase to suppress the voltage dependent errors responsible for the dead.The controller of the amplitude and timing of the phase jump is a jump of phase / voltage within the feedback signal of the electronic components of closing the loop of gyro of fiBra optics.The jump phase / voltage is provided to a frequ00b3u00eancia regularly enough to ensure that the fiber optic gyroscope will not have sufficient time to establish himself within the band dead before the SALTO phase / voltage be provided to electronic components to close the loop.By providing a jump of phase / amplitude voltage applicant with enough to move the signal out of the dead.The electronic components of the closure of the loop to take the average of the voltage dependent errors throughout the full range of voltage feedback.The process of taking the average of the error effectively eliminates the voltage dependent errors that cause the phenomenon of dead band and allows electronic components to close the loop to realizeThe actual speed of rotation for the fiber optic gyroscope.
