Diapason: multispectral laser radar for viewing and ranging of real scenes
Compact multispectral laser-radar sensor characterized by 6 wavelength channels (390nm, 420nm, 515nm, 590nm, 850nm and 1550nm) capable of performing simultaneous high-resolution (about 1mm at 10m of distance) scans of even large-scale real scenes for IR and 3D color imaging aimed aimed at purposes of fruition, cataloguing, dissemination, valorization, diagnostics and monitoring of the target of interest.
Application sectors
Problem to solve
With this technology, it is possible to monitor the degree of deterioration of large structures (churches and artworks, building facades, frescoed vaults, etc. ), as a result of aging, water infiltration, humidity, natural disasters such as earthquakes, attack of biological or chemical agents, both from the metrological and colorimetric points of view and by performing differential color analysis of the pigments of artworks of art of interest, up to distances of tens of meters and without the use of scaffolding to get close to the real scene under investigation. Moreover, by exploiting the penetration capacity of IR (infrared) radiation below the surface visible layer, it is possible to detect and emphasize also in areas not easily accessible the presence of possible hidden details or alterations in the initial phases, such as preparatory drawings, afterthoughts or hidden signatures in the specific case of paintings and frescoes or the presence of humidity and infiltrations.
Description
Diapason's compact laser radar sensor can reproduce real scenes at high resolution and monitor without the use of scaffoldings in a remote accurate and non-invasive way the deterioration of large structures (infrastructures, building facades, churches and artworks, frescoed surfaces, etc.) due to aging, humidity, water infiltration, natural disasters(e.g.earthquakes), attack of biological or chemical agents, both from the metrological and colorimetric points of view by performing differential pigment analysis of the targets of interest, up to distances of tens of meters. Moreover, by exploiting the penetration capacity of IR (infrared) radiation below the surface layer, it is possible to detect and highlight even in areas not easily accessible the presence of hidden details or alterations in the early stages, such as preparatory drawings, afterthoughts and hidden signatures in the specific case of paintings and frescoes. It can also be used for multispectral investigations and 3D reproduction of real scenes, such as crime scenes for forensic purposes.
