The Dead Sea Scroll

In 19th October 2010, Google and the Israel Antiquities Authority announced they are collaborating to digitize the whole collection of the Dead Sea Scrolls and will post them on the internet for anyone to access.
This project employs the MegaVision EV Hyperspectral system to digitally capture 30,000 scroll fragments using near-IR and multi-spectral imaging. These high resolution images can be easily enlarged. The multi-spectral photography, was intended to detect physical changes in the parchment scrolls  and to track their deterioration for preservation purposes. The multispectral Imaging also revealed or improved the legibility of parts of the text that have faded and discolored with age and are not visible to the naked eye.
The scrolls were discovered in the late 1940s and the 1950s in caves east of Jerusalem, near the ruins of Qumran on the Dead Sea. Scholars say the manuscripts, written between the second century B.C. and the first century A.D., provide important insights into the history of Judaism and early Christianity. They include the earliest known copies of books of the Hebrew Bible.

3D Hyperspectral imaging of the Lenox Globe

The Lenox Globe – held at  New York Public Library – is the oldest surviving globe to depict the New World. It was recently digitized using the combination of a 3D structured light scanner and the MegaVision hyper spectral system.
By imaging the globe from top to bottom and conducting a 3D scan of it, the researchers plan to provide a precise digital record of the object that will last for generations, giving scholars and members of the public a glimpse at what people knew about world geography in the early 1500s.
The researchers took 18 pictures around the globe’s equator, 39 images at various latitudes and one of the pole; then, they repeated the process for the Southern Hemisphere.
Although the globe looks spherical, it’s not perfect, which can cause distortion in the 3D digital replica. So, after taking the high-resolution color images, the researchers made 3D scans of the globe. By wrapping the 2D multispectral images around the 3D scan, they can get a much more accurate reconstruction of the globe.
A masterpiece of workmanship, the Lenox Globe measures 4.4 inches across (11.2 centimeters), and the hollow copper sphere is engraved with almost microscopic detail. The globe’s maker is unknown and its age is disputed, but based on the geography it depicts, some historians say the object was likely made between 1503 and 1507.

Livingstone’s Personal Documents

The MegaVision EV Multispectral system is used in the imaging of David Livingstone material at the National Library of Scotland.

Dr. David Livingstone was an African missionary, a medical doctor, explorer and advocate against the slave trade in Africa. In his final years, Dr Livingstone was reduced to writing on used newspaper and other found material with inks he made from berry juice.
Now, most of the material is virtually unreadable as paper has disintegrated and inks have faded. Using the The MegaVision EV Multispectral system , Dr Livingstone’s letters are photographed using 12 different wavelengths of light. when these images are enhanced using image analysis software, eroded text are revealed thus making it available for study.
The restoration of the letters will be done by researchers from Birkbeck College, University of London, the National Library of Scotland and the David Livingstone Centre. The documents will eventually be made available to the public through the Livingstone Online website.

Reproduction of Monet’s Villas at Bordighera

With the best details and color accuracy available in any camera system, the EV system is the ideal solution for reproduction of painting.
The Monet painting was captured at a 600 PPI resolution by stitching 8 images together.
To achieve the possibility of reproducing the Monet painting with visual appealing structures and shadows in brush strokes, a part of the capture process was to make an extra set of images in the visible light bands,  only illuminating the painting from one side.
By adjusting the image layers in the post production the dramatic effects of shadows and structures can be fully controlled.

Lincoln’s Gettesbury Address

The Manuscripts of the Gettysburg Address are normally kept in the Library of Congress, in a specially-designed, temperature-controlled, sealed display case to prevent deterioration. These manuscripts were removed from its protective environment and went on public display as part of activities celebrating Abraham Lincoln’s birthday in January 2009.
Taking advantage of this time when the manuscripts were outside its sealed cases, a team of imaging scientists used the The MegaVision EV Hyperspectral system to photograph the manuscript using 12 different wavelengths of light.

The Megavision EV system was chosen for several reasons:
-It exposed the manuscript with minimal illumination, thus limiting potential damage from harmful UV and IR light.
– The high resolution captures allows for easy enlargement for studies or reproduction.
– The 12 images captured would be the most color-accurate copy of the manuscript and will allow the manuscript to be accurately reproduced if necessary.
– Capturing in IR and near IR light, images also serve as a record of the physical condition of the manuscript and can be used to track its state of preservation.
