升级到第二代地面引力波探测器，最终在2015年首次直接探测到引力波，从而打开了观测宇宙的新窗口。这一杰出成就是LIGO和Virgo合作多年共同研发的结果。从那时起，在O1， O2和O3的观测运行期间，室女座和LIGO（激光干涉引力波天文台）都探测到了许多其他事件。自2020年4月以来，就在O3运行结束后，高级处女座经历了一段时间的仪器升级，目前仍在进行中，下一次观测目前计划于2022年年中开始。本文在简要介绍引力波探测之后，将概述先进处女座设计，其现状以及计划中的仪器升级到先进处女座+设计，这将推动探测器灵敏度达到可达到的最大极限，即在O4期间探测100 Mpc，在O5期间探测260 Mpc(2025-2026)[]。
The upgrade to the second generation of ground-based gravitational waves detectors, finally allowed in 2015 the first direct detection of a Gravitational Wave, thus opening a new window of observation on the Universe. This outstanding achievement was the result of many years of joint research and development (R&D) efforts by the LIGO and Virgo collaborations. Since then, during the observing runs O1, O2 and O3 , many other events have been detected by both Virgo and LIGO (Laser Interferometer Gravitational-Wave Observatory). Since April 2020, right after the end of the O3 run, Advanced Virgo has undergone a period of instrument upgrade, still in progress, before the next observing run at present scheduled to start in mid-2022. This paper, after a brief introduction on Gravitational Wave detection, will provide an overview about Advanced Virgo design, its status and the planned instrument upgrades to the Advanced Virgo+ design, which will push the detector sensitivity towards the maximum achievable limit that is a detection range for compact binary neutron stars of 100 Mpc during O4 and 260 Mpc during O5 (2025-2026) [].
