RIKEN opens THz database to public | |
| |
|
RIKEN has opened for public use its database on terahertz wave (THz-wave) absorption spectrum of a wide range of materials. The database will provide support for industry with information on a variety of materials, such as 164 kinds of organic substances and 18 kinds of inorganic substances. RIKEN opened the database online at the end of Jan., 2008. The Tera-Photonics Laboratory of RIKEN's Frontier Research System's Terahertz-wave Research Program has been collecting THz-wave data on various materials since 1998, with help from other research laboratories, to create a system that researchers, industrial developers and educators all over the world can use freely online. The THz band is a region of the electromagnetic spectrum between submilli-wave and infrared. The physical properties of the THz band have been attracting attention recently in many areas, including basic science and industrial applications. This makes them potentially useful in a range of fields, including medical imaging, airport security, spectroscopy and astronomy, as well as in communications and nondestructive testing in manufacturing. RIKEN's database contains data on various materials' transmission spectra, or the way they absorb THz-waves. Collecting and sharing information is crucial in THz-wave research, since the field is still quite new, so the RIKEN database will be an invaluable aid for researchers in materials, life and medical sciences. The data includes not only the absorption spectrum shape but also the conditions under which the material was measured. For instance, the spectrum shape can change greatly when the temperature changes, and measurement conditions will be offered in the database at the same time. The database, which was featured in an article in Nature Photonics vol. 2 no. 2, is available for researchers all over the world to use and contribute to, and can be accessed at http://www.riken.jp/THzdatabase/. |
