摘　　要：This study proposes a novel interferometric fiber optic gyroscope(IFOG)based on an integrated optical chip,application-specific integrated circuit,and small-diameter sensing coil.The overall size and weight of the prototype are 30 mm × 30 mm ×30 mm and 68 g,respectively,making it the smallest closed-loop IFOG,to the best of our knowledge.A static experiment shows that the bias stability of the integrated IFOG is very close to the theoretical accuracy limit determined by the fiber coil and can satisfy the requirements of near-navigation-grade compact inertial navigation systems.
