Picometer topological optical metrology at a million measurements per second

Picometer topological optical metrology at a million measurements per second
Picometer topological optical metrology at a million measurements per second
Using a nanowire as example, we experimentally demonstrate all-optical metrology with resolution up to 80 pm and sampling rate up to 1M fps. Here, topologically structured light scattering is used to visualize nanoobject’s trajectory with an algorithm discriminating instrumental instabilities and movements of the object relative to its immediate environment.

Abstract

Using a nanowire as example, we experimentally demonstrate all-optical metrology with resolution up to 80 pm and sampling rate up to 1M fps. Here, topologically structured light scattering is used to visualize nanoobject’s trajectory with an algorithm discriminating instrumental instabilities and movements of the object relative to its immediate environment.
