Rough diffraction gratings: applications to linear optical encoders

In this Thesis work we present theoretical, numerical and experimental analyses of the behavior of non-perfect diffraction gratings. We have permormed an analyses of diffraction gratings engraved on a steel tape. This kind of gratings can be found in industrial devices such as optical encoders for l...
