Generation of structured illumination with resonant mems

In recent years, there is an increasing interest in the demonstration of new optical and instrumental configurations for realizing structured light suitable for 3D surface imaging. This innovative technique has the advantage, with respect to traditional cameras and imaging sensors, to take into account the depth information of the object. In this work, we have investigated the possibility to generate structured light using a single-axis torsional micromirror realized by MEMS technology and diffractive optical elements working in transmission.
