摘要：
日本未来的空间引力波探测项目计划命名为DECIGO。为完成包括以通过探测原初引力波来验证宇宙暴胀为主要目标在内的各项科学任务，DECIGO被设计为在0.1至1 Hz频段具有高灵敏度，臂长为1000 km。此外，在这些臂中使用Fabry-Perot腔已在DECIGO项目中确立。本文中，我们以观测来自宇宙暴胀和致密双星系统的引力波的可能性为指标，仔细审视了Fabry-Perot腔对推进该项目的重要意义。结果表明，使用Fabry-Perot腔对探测这些引力波极为有利，并有望为引力波天文学打开一扇新窗口。
英文摘要：
The future Japanese project for the detection of gravitational waves in space is planned as DECIGO. To achieve various scientific missions, including the verification of cosmic inflation through the detection of primordial gravitational waves as the main objective, DECIGO is designed to have high sensitivity in the frequency band from $0.1$ to $1$ Hz, with arms of length 1000 km. Furthermore, the use of the Fabry-Perot cavity in these arms has been established for the DECIGO project. In this paper, we scrutinize the significance of the Fabry-Perot cavity for promoting this project, with a focus on the possibility of observing gravitational waves from cosmic inflation and binary compact star systems as indicators. The results show that using the Fabry-Perot cavity is extremely beneficial for detecting them, and it is anticipated to enable the opening of a new window in gravitational wave astronomy.
