- Аннотация: The sensing of phase front of the vortex laser beams has been carried out with the help of a Hartmann-Shack sensor. The vortex beam is generated in the form of a Laguerre-Gaussian beam (LG0 1 mode) with the help of the special helicoidal phase plates manufactured by the kinoform technology. The measured shifts of focal spots on the hartmannogram are compared with the calculated shifts. From the measured wave front tilts the reconstruction of singular phase surface has been performed with using the novel reconstruction technique. The phase surface reconstruction is demonstrated in the case of distorted vortices as well. The correction of an optical vortex is undertaken in the close-loop adaptive system including the bimorph deformable piezoceramics-based mirror.
