Infinitesimal optical singularity ruler for three-dimensional picometric metrology

Abstract Optical metrology with picometer-scale precision in three-dimensional space is of considerable importance in modern physics and state of the art technology, optical interference is an effective method, but techniques with rapid spatial variation have the potential to enhance measurement pre...
