Radiation Hardening Fiber Optic Gyro Design Applied in Space

摘要

Having advantages of solid configuration, small size, lower weight, controllable cost, and high navigation performance, fiber optic gyro (FOG) has been attracting much attention from space industry. Applied in space, the biggest challenge FOG facing is space radiation. The paper shows research activities at BUAA related to space radiation effects on fiber optic gyro. Studies discussed here include: ① radiation effects on optical components and electronic components of FOG as well as FOG itself; ② Test facilities; ③ Radiation hardening design for FOG used in space.
