    Near infrared spectra and hyperspectral imaging of medieval fortress walls in Carcassonne: a comprehensive interdisciplinary field study2016In: NIR news, ISSN 0960-3360, E-ISSN 1756-2708, Vol. 27, no 3, p. 16-20Article in journal (Other academic)
    Abstract [en]

    A comprehensive study has been launched in the medieval fortress of Carcassonne involving a cooperation between the universities of Umeå and Rennes, and the research institute of IRSTEA of Montpellier. This study aims to combine several spectroscopic techniques in order to resolve archaeological problems related to which raw materials were used during the city wall construction, and also to improve our understanding of the different phases of construction and use of the city walls. This study was also used for elucidating the different qualities and weak points of the applied field methods.

    Alternative ways of achieving nearinfrared information in field images: a tentative approach2015In: NIR news, ISSN 0960-3360, E-ISSN 1756-2708, Vol. 26, no 8, p. 7-10Article in journal (Other academic)
    Abstract [en]

    Commercial digital cameras can be converted into a tool for NIR field multivariate imaging. Results obtained using such a tool are far less sophisticated than those obtained by NIR spectrometers or hyperspectral imagers but they may often be useful enough for making quick conclusions during field work.

    Abstract [en]

    NIR spectroscopy offers the field archaeologist the possibility to rapidly screen a site. The screening results are useful in themselves or can be used to plan a sampling campaign for slower methods or to pinpoint sites of interest.

    Portable near infrared spectroscopy and imaging on archaeological sites and samples in the MOBIMA project: Part II. The potential of hyperspectral field imaging2014In: NIR news, ISSN 0960-3360, E-ISSN 1756-2708, Vol. 25, no 8, p. 8-12Article in journal (Other academic)
    Abstract [en]

    In a previous article, the use of portable near infrared (NIR) spectrometry for archaeological purposes was explained and illustrated. It was also mentioned that there is a difference in speed between point-wise spectroscopy and imaging, whereby imaging can give a similar wavelength range as the spectroscopy but also has a very large number of spatially-referenced pixels collected very quickly. In the present Part II article, this imaging aspect will be further explored.
