There are two main methods of detecting gravitational waves currently in use. One method is to measure
changes induced by gravitational waves on the distances between freely-moving test masses using coherent
trains of electromagnetic waves. The other method is to measure the deformation of large masses at their
resonance frequencies induced by gravitational waves. The first idea is realized in laser interferometric
detectors (both Earth-based [105, 141, 53] and space-borne [85, 137] antennas) and Doppler tracking
experiments [14], whereas the second idea is implemented in resonant mass detectors (see, e.g.,
[22]).
