The dynamic spatial control of light fields, including shaping and turbulence simulation, is essential for applications such as free-space optical communication. We propose a method generating rapidly switching structured beams with coherently superposed modes optional levels using digital micromirror device (DMD). composite holograms encoded by Lee Superpixel methods are quantitatively analyzed in terms fidelity efficiency both can generate under high fidelity. loaded intensity verified measuring the Strehl Ratio generated beams, propagation stability reconstructing three-dimensional field through stack cross-sectional images. A more compact robust experimental system adopted, which reduces power loss than traditional two consecutive modulations improves speed phase-only modulators. measurements consist theoretical simulations, will promote DMD beam generation.
