News What are Terahertz waves? 12 June 2017 Terahertz waves, also called submillimeter waves, T-Rays, T-Waves are electromagnetic waves in the frequency band between 300 GHz and 10 THz (1THz=10^12 Hz). Wavelengths of radiation in the terahertz band range from 30 µm to 1 mm. That’s why they are also known as submillimeter waves. Terahertz radiation lies between microwaves and infrared light regions of the spectrum and it shares some properties with each of these. Like infrared light, terahertz waves can travel in a direct path from the source to the receiver, and manipulated with optical elements. On the other side, like microwave radiation, they are non-ionizing (they don’t carry enough photon energy to ionize (remove an electron) atoms or molecules) and can penetrate a wide variety of non-conducting materials. Among them there are clothes, skin, paper, cardboard, wood, plastics, ceramics etc. On the other hand, Terahertz waves cannot penetrate metal, water and liquids. These properties are making the T-Waves attractive candidates for the brand-new applications in a various fields (imaging, non-destructive testing, healthcare, security and defense…). For example, due to a non-ionizing property, Terahertz waves can penetrate some distance inside the body tissue, and as they are inoffensive for living organisms, they can be a good replacement of the X-Ray imaging. Still, we don’t see the Terahertz waves; they are naturally occurring and surrounding us in everyday life. Yet this region of spectrum remains the least explored mainly due to the technical difficulties. But recently, thanks to advances in a technology, new systems were developed to both generate and measure/detect those waves. These decisive advances are promising for a number of applications. Some interesting physical properties... read more Interview with Peter Ertl, Head of the Photo Studio at the Albertina Art Museum in Vienna. 29 March 2017 Please introduce yourself and tell us about your work at the Albertina photo studio. I have worked as a trained photographer at the Albertina for more than 30 years and I am now head of the photo studio. At first I worked with black and white photography; then we moved on to using scan backs. Now we work exclusively with the latest digital technology, including a high-resolution camera by PhaseOne and the SupraScan high-performance scanner (SupraScan Quartz A1 – Product) by i2s. I am assisted in the studio by my colleague Ms Pohankova, who is also a trained photographer. Our work has two main focus areas. We are currently in the process of digitalising our own stocks for long-term archiving, online presentation (http://sammlungenonline.albertina.at) and further processing, such as e.g. exhibition catalogues. And we also create high-quality scans of our stocks, which can be ordered by external customers for a fee. We work with a wide variety of objects. The Albertina owns books, prints and paintings of all sizes. However, we mainly scan prints and newspapers up to a size of DIN A1. Almost all of the objects are unique and highly valuable. We therefore have to proceed very carefully during digitalisation. How did you become interested in “book scanners”, given that you had previously worked very successfully with camera systems? For a number of reasons, we began to work more intensively on book scanning. At the Albertina, we are unable to suspend the camera directly above the material for safety reasons. As a result, we have to lean the material against a wall. Yet we still have to align... read more Manuel Valls visits i2S 28 October 2016 Yesterday, on Thursday October 27, things were buzzing at i2S. We had the great privilege of meeting the Prime Minister, Manuel Valls, as part of the “Factory of the Future” program launched by the New Aquitaine region. read more Events Liasa [Library & Information Association of South Africa] 10/10/2016 - 14/10/2016 Durban IRMMW-THZ TERAHERTZ conference 25/09/2016 - 30/09/2016 København S Terahertz imaging technical Workshop 12/04/2016 Talence Med-IT El Djazaïr 26/10/2015 - 29/10/2015 Alger i2S @Gitex 18/10/2015 - 22/10/2015 Dubai Twitter Tweets de @i2SBeVisionary Job Investors Kit média Contacts Terms of use Facebook Twitter Google RSS
