Atomic-beam holographic interferometer

An atomic beam holographic interference device comprises an outer shell, an atomic beam source in the vacuum chamber inside the outer shell, and a receiver facing the advancing direction of atomic beams. A zone plate is arranged between the atomic beam source and the receiver; a pinhole aperture is...

More Information
Summary:An atomic beam holographic interference device comprises an outer shell, an atomic beam source in the vacuum chamber inside the outer shell, and a receiver facing the advancing direction of atomic beams. A zone plate is arranged between the atomic beam source and the receiver; a pinhole aperture is arranged on the first-order diffraction focus of the zone plate, on the plane where the focus is vertical to the advancing direction of atomic beams; the object to be measured is arranged beside the pinhole aperture. The output terminal of the receiver is connected with a computer. Compared with the prior art, the utility model is of simple structure and high interference efficiency, with the sensitivity seven orders of magnitude higher than an optical interferometer. The utility model can measure any action that can cause interference phase change.
