Detection of structured laser beam centroid and its use for alignment
A Structured Laser Beam (SLB) [1] is a pseudo-non- diffractive optical beam. Its transverse profile is similar to a Bessel Beam (BB), hence its bright central core is sur- rounded by concentric circles. SLB can propagate with very low divergence over long distances. Propagation over 200 m has been t...
