High‐Speed Nanometer‐Scale Imaging for Studies of Nanowire Mechanics

The ideal shape of nanowires means that their position within an optical image can be determined with a precision given by the signal-to-noise ratio rather than by the wavelength. This is the basis for a stroboscopic imaging technique capable of tracking the bending and oscillation of a single nanowire in space and time (see image). The achieved precision is below 1 nm, more than two orders of magnitude better than the diffraction limit.
