ABSTRACT: There are many optical methods which are applied in metrological measurements, particularly to determine the length of distances, the area of surfaces, the topography of a 3D surface, the spatial orientation of a surface, the volume of a 3D body, the 3D object repositioning, and their respective variations as a function of external or internal stimuli. Most of them are used in static measurements. Also, they are used in quasi-dynamic measurements, as in the case of small changes of the physical variable under observation. They are employed in scientific and technological applications and in biometrology. Selected references on these subjects are 1-23. This poster describes an experimental approach to determine the topography of an off-set MW paraboloidal satellite antenna by structured illumination.
