| 摘要 |
We built a fiber link system to connect the astronomical laser frequency combs (astro-comb) and the HRS spectrograph for Chinese 2.16m telescope in Xinglong. Fiber noise deteriorates the precision and stability of high spectral resolution fiber-fed spectrograph, especially when the astro-comb is used as calibrators. In order to optimize the performance of the astro-comb fiber link system, it is essential to suppress the fiber noise. The polygonal fiber is used to improve the scrambling and a vibrator attached to fiber is used to eliminate the speckle. The experiment results show good suppression of fiber noise with polygonal fiber, especially for the octagonal fiber, together with dynamic agitation by a vibrator. |
