Paper Abstract

In the previous paper the new scanning technique was proposed. The sample was illuminated by a focused laser beam with an optical vortex. The vortex was introduced to the laser beam by vortex lens. When shifting the vortex lens the optical vortex in the focused beam moves and scans the sample. In order to use this new scanning technique for microscopic imaging a method for the focused vortex beam phase reconstruction is necessary. In this paper a fast and accurate method for phase reconstruction of the focused vortex beam is investigated. It is shown that the propose method is accurate enough to explore even small optical vortex shifts inside the focused beam.
