New Technology Reads Ancient Documents without Opening Them
Attempting to open very old books and records without damaging them can be difficult.
But scientists in Switzerland say they have improved a method to read age-old documents without even touching them.
Researchers at the Swiss Federal Institute of Technology are using radiation, in the form of x-rays, to create images of the documents. This method is called X-ray computed tomography or X-Ray tomography.
On a recent day, the researchers used X-ray tomography to read from a small 14th century document.
Giorgio Margaritondo is working on the project. Reading from the document, he noted, "in the year 1351, a young lady from Venice...wrote a testament, and then the testament was sealed, and remained sealed for all these many centuries."
Italian officials are planning to use X-Ray tomography to build an open digital system in the State Archives of Venice.
Margaritondo says, "What you find inside the Archives are not only small documents. But most of the items are huge volumes the size of a table, and so we must be able in the future to look inside them."
Many of the documents show signs of weathering, and are easily broken.
Fauzia Albertin is also working on the project. She says, "We need a non-invasive technique to read inside them. Thanks to the use for thousands of years of iron-based inks we can read them using X-rays."
Albertin is also with the Swiss Federal Institute of Technology.
The researchers have a lot of work to keep them busy. The State Archives of Venice has a huge number of records. They were produced over a period of about 1,000 years. The documents cover about 80 kilometers of shelf space.

In brief, we should invest heavily in digital system.

Thanks to 幸亏
Thanks to that job I became an avid reader.
Thanks to your help, we accomplished the task ahead of schedule.
瑞士联邦理工学院的研究人员正在利用X射线辐射制作这些文献的图片样本 。这种方法名为X射线计算机断层成像，或X射线断层成像 。
希奥尔希奥·马格里冬多（Giorgio Margaritondo）是该项目的研究人员 。他在读取文献的过程中发现，“公元1351年，威尼斯一名年轻女子……写下一份遗嘱 。随后这份遗嘱被封存，数百年来从未打开过 。”
福齐亚·阿尔贝坦（Fauzia Albertin）也是该项目的人员之一 。她表示，“我们需要一种无创性技术获取文献的内容 。好在这数千年的文献皆为墨水所著，我们才能利用X射线读取其中信息 。”
研究人员的日常工作繁重 。威尼斯国家档案馆收藏着大批文献，这些文献都是近1000年来的古老典籍，覆盖了近80千米的书架空间 。
