Paper Abstract

An efficient temperature measuring and monitoring method in an interferometric fiber-optic gyroscope (FOG) for space application is presented. Resource-saving digital temperature sensors and integrated optical-circuit temperature sensors are designed and separately implemented in a field programmable gate array and the second closed loops of FOG. A multipoint temperature measurement in FOG is conducted using both kinds of temperature sensors. An FOG status-monitoring strategy is proposed by defining a status index based on multipoint temperature information and heat-transmission model of our four-axis FOG structure. Temperature measurement and status-monitoring strategy are verified by experimental results.
