Abstract

By time-multiplexing (scanning) an optical trap and additional modulation of the laser intensity, it is possible to generate various optical potential landscapes along the scan direction. Interferometric position detection of particles diffusing in this line optical trap allows measuring the interaction between them at a kHz rate and with a precision of 10 nm.
