## DMD diffraction toolI presented in this tutorial the diffraction effects occurring in a DMD setup. It corresponds to a blazed grating effect and depends on the wavelength \(\lambda\), the pixel pitch \(d\), the incident angle \(\alpha\), and the angle of the micro-mirrors \(\theta\). Here is a simple app (see source code on Github) to calculate the criterion for optimal diffraction efficiency and the aspect of the diffraction pattern in the far-field when illuminating the DMD with a plane wave of incident angle \(\alpha\) with respect to the normal of the surface. |
