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