Roughness analysis / Photogrammetry

The Mex (Alicona) software allows to calculate the appropriate angles of inclination for the roughness analysis of a sample according to its nature. Then it allows to perform roughness analysis, 3D modeling, measuring height differences, etc.

example of application of Mex: 3D reconstruction of a diatomaceous earth
