Abstract:
The presence of small defects in micron-sized structured surfaces introduces small changes in the backscattering that can be assessed by means of an integrated parameter. In this work the influence of the optical properties of the substrate on this technique is analyzed for two different configurations: defect on the microstructure and defect on the substrate beside the microstructure.
