In recent times, we experimentally realized a quite efficient modeling of theshape of diffraction-resistant optical beams; thus generating for the firsttime the so-called Frozen Waves (FW), whose longitudinal intensity pattern canbe arbitrarily chosen, within a prefixed space interval of the propagationaxis. Such waves possess a host of potential applications: in medicine,biomedical optics, optical tweezers, atom guiding, remote sensing, tractorbeams, optical communications or metrology, and other topics in photonic areas.In this work, we extend our theory of FWs -- which led to beams endowed with astatic envelope -- through a dynamic modeling of the FWs, whose shape is nowallowed to evolve in time in a predetermined way. And we experimentally createsuch dynamic FWs in Optics, via a computational holographic technique and aspatial light modulator. Experimental results are here presented for two casesof dynamic FWs, one of the zeroth and the other of higher order, the last onebeing the most interesting, consisting in a cylindrical surface of light whosegeometry changes in space and time.
