Abstract A fuzzy logic-based embedded system to characterize materials and metamaterials is presented. Trapezoidal and Gaussian profiles, used as membership functions, allow to classify materials despite variations on light intensity. The results on various materials show the capacity of the system to calculate the refractive index as a complex number, through a fourth order equation. Since all the roots of the equarion, including imaginary ones, the system allow to characterize metamaterials. The embedded character of the systems allows to use it as an external module for most commercial equipments.

In the recording of refractive index fields, the exceedingly high monochromatic brightness of laser light sources opens up new possibilities where applications to very fast or highly self-luminous phenomena are concerned. The properties of laser light, however, pose special problems, as well as presenting special opportunities. These are examined in relation to schlieren recording, deflexion mapping, shadowgraphy and interferometry. The ultimate aim is the development of a ‘versatile' optical system which is capable of fulfilling all these functions with only minor readjustments in its optical components. This is achieved, for laser light, without either the expensive apparatus, or the considerable intensity losses with which such systems are otherwise associated.
