  Bessel beams are non-diffracting light structures, which can be produced with
simple tabletop optical elements such as axicon lenses or ring spatial filters
and coherent laser beams. One of their main characteristic is that Bessel beams
maintain their spatial characteristics after meters of propagation. In this
paper we demonstrate a system and method for generating Bessel beams from
amorphous speckle patterns, exploiting adaptive optimization by a spatial light
modulator. These speckles are generated by light modes transmitted through a
scattering curtain and selected by a ring shaped filter. With the proposed
strategy it is possible to produce at user defined positions, reconfigurable,
non-diffracting Bessel beams through a disordered medium.
