Method and device for suppressing light source intensity noise of fiber optic gyroscope

摘要: The invention discloses a method and device for suppressing light source intensity noise of fiber optic gyroscope. comprises the following steps of: estimating an effect by utilizing signal correlation coefficient; judging whether to perform suppression according estimation result; when result meets requirement,programming interference in field programmable gate array (FPGA) chip finish subtraction, so that component is suppressed; otherwise, prompting improve optical path or circuit gyroscope estimated requirement, performing subtraction. can be performed real time actual working environment gyroscope, reliability effectiveness are improved, situation rises rather than fall subtraction methodis prevented, random walk coefficient reduced, precision improved.
