Paper Abstract

In this paper authors present the method for measurement of micro displacements along optical axis of the reflective object. Three separate focused beams are used in those measurements. Those three plane waves are reflected by examined object surface and their interference tends to create regular lattice of the optical vortices. In this paper authors present test results of sensitivity of an actual measurement system.
