An incised and colored ceramic vessel was used as example within an effort to judge the effectiveness of ultraviolet induced and Reflected UV RTI visible fluorescence RTI.
The RTI data record happened in a university’s historical imaging lab, utilizing a UV-VIS-IR changed DSLR camera, sufficient filters and light. The reflected ultraviolet-RTI datasets were taken having an IR screen filter and a UV transmitter. The ultraviolet induced apparent fluorescence RTI datasets were taken with an ultraviolet screen filter and an IR.
The method offered in one single file a mix of UV and axial imaging. It’s significant the axial placement of light sources in reflected ultraviolet imaging is beneficial and it is suggested for saving of streaks and scores.
The ultraviolet induced apparent fluorescence image shows the remains of preservation resources at first glance of the prior repairs as well as the ceramic skyphos, due to the apparent fluorescence emission of common adhesives. The ultraviolet induced apparent fluorescence RTI allows the consumer to practically go rays source round the item resulting in numerous different visualizations. By doing so the conservator may achieve a much better knowledge concerning the morphology of the prior repairs.
