Applications of Minimally Invasive Imaging Techniques in Cultural Heritage

Dear Colleagues,

Optical imaging contrast modalities are powerful diagnostic tools for Cultural Heritage (CH) studies, facilitating the accurate control of cleaning interventions. Minimal or non invasive imaging techniques have the potential to provide new insights for the assessment of appropriate conservation methods that have to be applied for various CH objects of high artistic or cultural significance. CH artifacts can strongly benefit from the availability of minimally invasive approaches, providing fruitful key information such as determination of the different layers, their precise thickness or surface topography, revealing the hidden objects and the cracks in the layers, etc.

The aim of this Special Issue is to present recent advances of the applications of relatively new, minimally invasive imaging methods as diagnostic tools in the service of CH for the in situ analysis and studies in real objects. We are interested in original papers and reviews that address the development, optimization and implementation of imaging techniques for obtaining novel and complementary information from various multicomposition, multilayered CH objects and substrates.

Techniques include, but are not limited to the following:

• Optical Coherence Tomography (OCT)
• Raman spectroscopy
• Laser induced Fluorescence (LIF)
• THz
• Multi-spectral
• Non-linear
• Photoacoustic
• Diffuse Reflectance
• Interferometric

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
