The technology has been developed over the past 25 years, implementing new innovative components during time. The methodology provides a set of 2D acoustic images in different frequency intervals, for revealing the structural damage (detachments, delaminations, structural weakening) in multi-layer structures and artworks (mural paintings, frescoes, ceramic panels, panel paintings). Recently, interesting results have been obtained in studies of the water related deterioration effects on antique masonry structures.

The invention consists of a method and apparatus for the delivery at low pressure (equal to or less than 10^-7 Torr) of monoatomic fluorine for reaction with surfaces in an ultra-clean environment. Thanks to the low pressure values involved in the proposed method, the risks associated with the use of fluorine are reduced to a minimum.

The proposed device is a semi-transparent screen that allows simultaneous viewing of what is beyond the screen and the images projected onto its surface. It consists of two thin glass plates with reflective elements arranged as microlenses, embedded in a resin. The projector's light is reflected by the elements towards the user's eye, while external light passes through the transparent layers without distortion. The transparency and brightness of the screen can be adjusted by modifying the reflective elements.
