Oxford researcher reveals hidden Alfred Tennyson text using innovative imaging techniques
Dr Michael J Sulliivan, Credit: John Cairns Dr Sullivan’s team has been using multispectral imaging, along with X-ray fluorescence and fibre-optic reflectance spectroscopy, to explore previously hidden parts of manuscripts. Multispectral imaging involves capturing a variety of images in different spectral bands, or wavelengths, from infrared to ultraviolet. By imaging a manuscript with over 40 different illuminations, the research team was able to draw out details beyond the normal visual…
