Abstract

Scanning vortex microscope is a system in which sample is scanned by a Gaussian beam carrying optical vortex. We report on a new method in which the sample is scanned by moving the optical vortex inside the focused beam spot. Figure 1 shows a scheme of the optical system. The vortex lens shift induces a precise nanometre shift of the vortex point (i.e. point where the phase is undetermined) inside the focused spot. When moving the vortex lens along a straight line vortex point goes along a straight line of much smaller size and different orientation. There is a specific distance between the focusing lens and sample plane at which optical vortex is highly sensitive on sample topography. In this special plane vortex point’s movement is perpendicular to the vortex lens’ shift. Moreover, the angle of vortex point’s trajectory changes in a very rapid way. In the paper we investigate the dynamics of the vortex shift induced by different setup parameters.
