Charte de calibrage UV

Une charte de calibrage photographique de la fluorescence sous UV enregistrée dans le visible est désormais disponible aux Etats-Unis chez UV innovations. Elle a été développée spécialement pour l’imagerie scientifique du patrimoine par Paul Messier, restaurateur de photographies et responsable du Lens Media Lab à l’université de Yale.

Le protocole de prise de vue tel qu’il est appliqué au C2RMF est disponible ici : http://copa.hypotheses.org/297

Target-UV™ & UV-Gray™

Target-UV™ is a calibration reference to control color and intensity of UVA induced visible fluorescence.

UV-Gray™ is used to set camera white balance using a variety of UVA radiation sources.

Both Target-UV™ and UV-Gray™ are made from stable inorganic pigments insuring accuracy and repeatability over many years of use. For more information on permanence of the Target-UV™ and UV-Gray™, see this paper.

The Target-UV™ increases the consistency and evidentiary value of UV/visible fluorescence images. This is achieved by the unique structure of the Target-UV™, which produces a neutral gray fluorescence when exposed to UVA radiation. The exact output of the fluorescence is dependent upon the radiation source used, allowing the Target-UV™ to adapt to different radiation sources. This allows for the creation and sharing of valuable data across cultural heritage institutions. These same benefits are now available for diverse fields, including forensic document examination and medical imaging.
