Hyperspectral imaging

While traditional digital imaging takes three wide wavebands of digital light (red, green and blue), hyperspectral imaging captures multiple narrow wavebands. RECENART has hyperspectral imagers for visible light and near infrared wavebands (VNIR, 450-850 nm) and for short wave infrared (SWIR, 1000 – 1700nm). Fine optical instruments combined with novel computational techniques make it possible to conduct colorimetric studies, determine the substances in the artwork, and reveal the underdrawings which may include erased text and hidden signatures.

With hyperspectral imaging it is possible to research:
-       Precise colormetric studies
-       See under different paint/ink/color layers
-       Determinate different substances on artefact
-       Reveal almost vanished texts
