A high accuracy measurement method based on vortex polar axis rotation phase-shifting interferometry (VPAR-PSI)
For higher precision phase shift measurement, based on the characteristics of vortex beam, the manuscript introduces phase shift directly through the polar axis rotation of the vortex beam. Compared to traditional grey-scale modulation, the proposed VPAR-PSI method introduces a phase-shifting direct...
