= Interferometric gravitational-wave detector = An interferometric gravitational-wave detector (or interferometric gravitational-wave telescope) is a gravitational wave detector that uses the wave interference to detect gravitational waves. Laser interferometers detect gravitational waves that extend and contract the distance between mirrors. Atom interferometers are proposed to detect gravitational waves, which would lengthen or shorten the distance between recombining atom clouds. Interferometric gravitational-wave detectors are one class of detectors and for more information about other types of instruments used for gravitational wave interferometry see the article on gravitational wave observatories.

Ground-based Laser Interferometery
Ground-based laser interferometers used for gravitational-wave detection are large, complex Michelson Interferometers.

Primarily measurement is the differential lengh measurement
