| Summary: | Hyperspectral imaging is relatively new method developed primarily for army applications with respect to detection of
possible chemical weapon existence and as an efficient assistant for a geological survey. The method is based on recording spectral
profile for many hundreds of narrow spectral band. The technique gives full spectral curve of explored pixel which is an unparalleled
signature of pixels material. Spectral signatures can then be compared with pre-defined spectral libraries or they can be created with
respect to application.<br><br>
A new project named "New Modern Methods of Non-invasive Survey of Historical Site Objects" started at CTU in Prague
with the New Year. The project is designed for 4 years and is funded by the Ministry of Culture in the Czech Republic. It is focused
on material and chemical composition, damage diagnostics, condition description of paintings, images, construction components and
whole structure object analysis in cultural heritage domain.<br><br>
This paper shows first results of the project on painting documentation field as well as used instrument. Hyperspec VNIR
by Headwall Photonics was used for this analysis. It operates in the spectral range between 400 and 1000 nm. Comparison with
infrared photography is discussed. The goal of this contribution is a non-destructive deep exploration of specific paintings. Two
original 17th century paintings by Flemish authors Thomas van Apshoven ("On the Road") and David Teniers the Younger ("The
Interior of a Mill") were chosen for the first analysis with a kind permission of academic painter Mr. M. Martan. Both paintings oil
painted on wooden panel. This combination was chosen because of the possibility of underdrawing visualization which is supposed
to be the most uncomplicated painting combination for this type of analysis. |
