Thanks to a new generation multispectral digital camera developed by IST-project CRISATEL, treasured documents and fine art can be captured with high resolution and reproduced in extraordinary colour for analysis, restoration and conservation.
The multispectral (ultraviolet to infrared) capture technique, employed in the JumboScan camera manufactured by consortium member Lumiere Technology, is a leap forward from the 100-year old tricolour concept of analogue photography. This older concept does not capture the entire visible colour spectrum. It replaces a large range of colours widely used in fine art, such as blue (Cobalt blue PB36) and red (Vermillion PR10), with other colours.
The JumboScan camera enables multispectral image acquisition that covers up to 95 - 100 per cent of the visible colour space versus the 50 - 70 per cent from the traditional RGB (red, green, blue) mode. "This means each pixel receives enough information to guarantee perfect colour restitution," says Pascal Cotte, CRISATEL project manager and president general manager at Lumiere Technology.

The well-known representation of chemical elements is just one example of how objects can be arranged and classified
The periodic table of elements that most chemistry books depict is only one special case. This tabular overview of the chemical elements, which goes back to...
Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.
The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs....
Researchers at Chalmers University of Technology, Sweden, have discovered a completely new way of capturing, amplifying and linking light to matter at the nanolevel. Using a tiny box, built from stacked atomically thin material, they have succeeded in creating a type of feedback loop in which light and matter become one. The discovery, which was recently published in Nature Nanotechnology, opens up new possibilities in the world of nanophotonics.
Photonics is concerned with various means of using light. Fibre-optic communication is an example of photonics, as is the technology behind photodetectors and...
