Scientists unveil high-sensitivity 3-D technique using single-atom measurements

25.03.2018 | Phys.org | www.phys.org

Researchers at Griffith University working with Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO) have unveiled a stunningly accurate technique for scientific measurements which uses a single atom as the sensor, with sensitivity down to 100 zeptoNewtons.

Using highly miniaturised segmented-style Fresnel lenses - the same design used in lighthouses for more than a century - which enable exceptionally high-quality images of a single atom, the scientists have been able to detect position displacements with nanometre precision in three dimensions.

High-sensitive 3D measuring technique

By intentionally moving their optics slightly out of focus, the researchers were able to measure displacements in all three dimensions, with the third direction determined by if the atom was shifting back into focus or further out of focus.
