Suboptical wavelength position measurement of moving atoms using optical fields

We demonstrate all-optical techniques for position measurement and localization of moving atoms with suboptical wavelength precision. Spatial resolution of 200 nanometers, with linearity over a few microns, is obtained by the methods which ultimately will scale to yield nanometer resolution limited...

Beschreibung
Zusammenfassung:	We demonstrate all-optical techniques for position measurement and localization of moving atoms with suboptical wavelength precision. Spatial resolution of 200 nanometers, with linearity over a few microns, is obtained by the methods which ultimately will scale to yield nanometer resolution limited by the uncertainty principle.
