摘要

A high precision time delay calibration system based on optical fiber switches and fiber coils network for the satellite range measurement system is proposed in this paper. To reach the high time delay precision, the Phase Stabilized Optical Fiber (PSOF), is proposed to use as time delay component instead of the Single Mode Fiber (SMF) to minimize the temperature dependence of transmission delay time. In order to verify the time delay precision, a low coherence interferometry which contains a Michelson interferometer and a Mach-Zehnder interferometer is used to measure the thermal coefficient of delay of the PSOF compared with the SMF from -20 to 60 degrees C. The result showed that by using the PSOF, the temperature error can be decreased by 4.15 times compared with using the standard SMF in the fiber based range measurement system.
