Paper Abstract

In this paper, we discuss the properties of propagation-invariant structured laser beams. We show the influence of different beam obstructions on the resulting structure of the beams. We present a reconstruction technique that, in spite of the remarkable self-healing properties of the propagation-invariant beams, allows us to define the size and shape of the obstructions encountered by the structured beam during propagation. The presented technique may have several practical applications in the fields of photonics and laser optics, including high resolution microscopy, optical information processing, and optical cryptography.
