Design & Analysis of System with Diffractive Light Diffuser Generating the LightTrans Logo

Diffractive diffusers can be designed to create any pattern. Here we demonstrate some possibilities of VirtualLab Fusion to design, optimize, model and simulate such diffractive optical elements (DOE) and the whole system to project our company's logo high up on a building. There are different approaches for generating light patterns. With a coherent laser light and a diffractive diffuser element, good efficiencies and interesting light textures can be achieved, which will be shown.
