Abstract
One of the challenges for the Optical Vortex Scanning microscope is to find the effective procedures for surface topography reconstruction. We proposed an experimental setup to support solution of this problem. The Spatial Light Modulator (SLM) is used as a phase object. SLM allows to generate phase disturbance in the range 0-2π, which can be easily introduced into the beam carrying optical vortex. Our system gives an opportunity to measure optical vortex response due to phase modifications introduced by the SLM and investigate vortex sensitivity. We tested how the object position, size affects vortex and position of the vortex point inside the beam.
