| Research Abstract |
We have developed a high-resolution test spectrograph and other inspection tools to examine fiber-link systems which will connect Okayama 188-cm telescope and the high dispersion spectrograph, HIDES. With these instruments, we optimized throughput of a high-efficiency fiber-link mode as well as confirmed that effect of fiber modal noise on a spectrum was limited for the mode. Our research considerably contributes to the completion and open use of the fiber-link system.
