Optimal design to improve the quality and curing efficiency of the optical fiber coil
Fiber coil serves as the core sensitive element of fiber optic coil,and its quality directly affects the whole performance of fiber optic gyroscope.By optimizing the winding and curing process of the fiber optic coil,the quality and curing efficiency of the fiber optic coil can be improved.Firstly,a high-precision optical fiber coil frame device with adjustable slot width is designed to adjust the optimal width-to-height ratio of the optical fiber coil.The experiment results show that the zero bias at full temperature is most stable when the width-to-height ratio is close to 1.Secondly,a curing device capable of simultaneously rotating and curing multiple fiber optic coils is designed with four fiber optic coils being cured simultaneously using this device.Comparing with the unrotated fiber coils,the stability of full temperature bias of fiber optic gyroscope is improved by at least 0.026°/h in the temperature range of-45℃to 75℃,and the stability of full temperature bias is better than 0.024°/h.
