摘要

Abstract: Optical fibers are currently under consideration for use in spacecraft systems as an essential component of rotation sensors and fiber optic gyroscopes. Many of these spacecraft systems will encounter substantial radiation doses over the mission life. These applications require the use of single-mode polarization-maintaining fiber. Prior to use in space, the radiation response of these fibers must be known. This paper investigates the radiation sensitivity of a type of PM fiber, based on elliptical wave guide principles rather than stress- induced birefringence, up to a total dose of 225 krad. The results indicate that applications utilizing the new fibers will survive the long term radiation environment in space.!15
