Progress in Gravitational Wave Detection
Cheng JingQuan;Yang DeHua
Abstract:
General theory of Einstein＇s relativity predicts the existence of gravitational wave when mass is accelerated. However, no material has direct effect when the gravitational wave passes. Therefore, gravitational wave can only be detected indirectly. The effort in gravitational wave detection was started in the 60s of last century by using a huge cylinder of aluminum. This paper introduced all the relevant projects in the gravitational wave detection. These projects in- clude Weber＇s bar, Laser interferometer Gravitational wave Detector （LGD）, Laser Interferometer Gravitational wave Observatory （LIGO）, GEO600, VIRGO, TAMA300, Advanced LIGO, Large scale Cryogenic Gravitational wave Telescope （LCGO）, and Laser Interferometer Space Antenna （LISA）.
Key words:
