Abstract:
    A method for compensating output angular speed information of optical fiber gyroscope in temperature-control free and closed loop light source type includes applying regression analysis means to obtain adapting relation of central wavelength of outgoing light from temperature-control free light source to temperature then compensating optical gyroscope output angular speed information drift caused by temperature variation in utilizing optical gyroscope to output relevant relation value of central wavelength at outgoing light on temperature-control free light source.
