High-resolution addressing of individual ultracold atoms, trapped ions or solid state emitters allows for exquisite control in quantum optics experiments. This becomes possible through large aperture magnifying optics that project microscopic light patterns with diffraction limited performance. We employed a digital micromirror device (DMD) of 684 by 608 pixels (with size of each pixel about 760 nm) to demonstrate a full spatial phase and amplitude control of a light beam. We will report the dynamic creation of a transversely rotated Hermit-Gauss mode along its propagating axis with the help of a fast amplitude digital micromirror device (DMD) and a superpixel technique. In addition, we will present how to create an arbitrary beam shaping.
