Hyperspectral Takes Old Maps Into New Territory

Posted by Christopher Van Veen on Thu, Mar 26, 2015

Late in 2014, Headwall sponsored a successful event at London’s Natural History Museum. The purpose of the gathering was to introduce curators and preservationists to the advantages and capabilities of hyperspectral imaging. Professionals in this field understand that the treasures under their control...paintings, documents, and artifacts...need to be preserved using the most advanced techniques available. Preservation largely means having an excellent understanding of the chemical composition of the underlying materials used to create the treasures. And what the eye cannot see, hyperspectral imaging can.

History Made, History Seen with Hyperspectral Imaging

Posted by David Bannon on Mon, Mar 03, 2014

As the market for hyperspectral sensing technology moves forward and advances, Headwall’s Application Engineering team has been able to gather a rare view into the past through the hyperspectral scanning of some of the most important historical artifacts and papers in the United States. For the first time ever, hyperspectral VNIR and SWIR imaging was conducted on key historical documents from the US Civil War period.
