Nanometric position metrology with topologically structured light

Nanometric position metrology with topologically structured light
Nanometric position metrology with topologically structured light
We introduce a new ‘optical ruler’ concept, which allows for single-shot, real-time detection of nanometric displacements down to λ/400, through the visualization of singularities in a topologically structured optical field using a polarization-sensitive camera.

Abstract

We introduce a new ‘optical ruler’ concept, which allows for single-shot, real-time detection of nanometric displacements down to λ/400, through the visualization of singularities in a topologically structured optical field using a polarization-sensitive camera.
