| The optical measurement of surface separation is based on thin-film interferometry. |
| Since the field of gravity wave interferometry is still so new, the researchers involved come from diverse backgrounds. |
| The unique advantage of interferometry is that the wavelength or frequency of the radiation used acts as an inherently precise measuring device. |
| Until this breakthrough, laser interferometry had been the poor cousin to bars in the gravity wave game. |
| Researchers use ground-based lasers and optical interferometry to detect gravity waves. |
| This paper presents a technique for measuring object-vibration phasors of higher amplitudes in phase-modulated holographic interferometry. |
