| A meaningful test of Radius system performance required confirmation of the interferometer concept. |
| The flip causes a tiny shift in the cantilever's vibration frequency, which is recorded by the laser interferometer. |
| This dynamic interferometer with a holographic optical element produces four phase-shifted interferograms imaged on a single detector. |
| Some of the light that is reflected from the cylinder groove is scattered, and does not re-enter the interferometer. |
| It should be noted that the lengths of the arms of the interferometer on ground-based gravity wave detectors are on the order of 1 kilometer. |
| This is one of the scientific objectives of the large decametric interferometer LOFAR, which should be operational in 2007 in Holland. |
