Abstract:
PCT No. PCT/EP94/00050 Sec. 371 Date Jul. 17, 1995 Sec. 102(e) Date Jul. 17, 1995 PCT Filed Jan. 10, 1994 PCT Pub. No. WO94/16296 PCT Pub. Date Jul. 21, 1994A very low amplitude interferometer suitable for detecting gravitational waves is disclosed. The interferometer has an optical cavity consisting of a glass plate sandwiched between two three-dimensional interferometric arrays and contacting a body in which micro-vibration is to be sensed. The interface between the interferometric arrays and the glass plate entraps thin layers of air. A coherent light source is used to illuminate one of the interferometric arrays. Micro-vibrations transmitted through the glass plate will affect the air layers sufficiently to render these vibrations detectable through interference patterns created by the reflected coherent light on a display screen.
