Shedding light on medieval manuscripts

It is not every issue that one of our articles starts with a quotation in medieval English, and it is appropriate as two of our articles cover the use of spectroscopy in cultural heritage. This is yet another field where the rich information provided by spectroscopy, along with its non-destructive nature (for many techniques), portability and ability to generate chemical images make it the answer to many questions. Kate Nicholson, Andrew Beeby and Richard Gameson are responsible for the medieval English at the start of their article “Shedding light on medieval manuscripts”. They describe the general use of Raman spectroscopy for the analysis of historical artefacts, and, in particular, their work on medieval European manuscripts and 18th century watercolour pigments. They stess the importance of checking the actual laser power density to avoid damage to priceless artefacts.

Infrared spectroscopy as a tool to study plant cuticles

Much of the exterior surface of plants is covered by the cuticle. This plays a vital role in protecting the plant from water loss, attack by pests and pathogens and damage from UV radiation. Infrared spectroscopy is very useful in characterising cuticles, as we learn in “Infrared spectroscopy as a tool to study plant cuticles” by José Heredia-Guerrero, José Benítez, Eva Domínguez, Ilker Bayer, Roberto Cingolani, Athanassia Athanassioua and Antonio Heredia. The authors point out that, whilst still in its early stages, infrared spectroscopy has provided valuable information about the functional groups, chemical structure and arrangement and interactions of plant cuticle components.

Hyperspectral sensor ranged for UAVs and other platforms of limited payload size

15 September 2015

SPECIM have introduced the new range of AisaKESTREL pushbroom hyperspectral sensor systems for unmanned aerial vehicles (UAVs). They are built to the same data quality requirements as SPECIM’s AisaEAGLE and AisaFENIX sensors and have a ground sample distance (GSD) of 5–10 cm which is the same as other airborne sensor technologies like orthophoto cameras and LiDARs, with which hyperspectral data is complementary.
