What is diffractometry, how it works?

Figure 1. Experimental setup that illustrates the diffraction of light by a textured sample. IRIS Technology Group is developing an optical inspection technique for the PROMETHEUS system, which will be used to monitor the laser texturing process. It is based on diffractometry, an optical method that analyses the diffraction pattern produced by a microstructured surface when light interacts with it. Combined with appropriate data analysis approaches, the diffractometry technique will facilitate the detection of process deviations and thus the evaluation of the texturing quality. This will help to ensure that the envisaged use cases in the PROMETHEUS project achieve the required surface functionality."
