Using ultrafast beams of extreme ultraviolet light streaming at a 100,000 times a second, researchers from the Friedrich Schiller University Jena, Germany, have pushed the boundaries of a well-established imaging technique. Not only did they make the highest resolution images ever achieved with this method at a given wavelength, they also created images fast enough to be used in real time. Their new approach could be used to study everything from semiconductor chips to cancer cells. The team will present their work at the Frontiers in Optics, The Optical Society’s annual meeting and conference in San Jose, California, USA, on 22 October 2015. The researchers’ wanted to improve on a lensless imaging technique called coherent diffraction imaging, which has been around since the 1980s.Spot UV LED Curing To take a picture with this method, scientists fire an X-ray or extreme ultraviolet laser at a target. The light scatters off, and some of those photons interfere with one another and find their way onto a detector, creating a diffraction pattern. By analyzing that pattern, a computer then reconstructs the path those photons must have taken, which generates an image of the target material — all without the lens that’s required in conventional microscopy. 上海和沁光电科技有限公司公司电话：021-60523084 公司地址：上海市松江区施惠路555号2幢3楼公司网址：http://www.greatuv.com 公司邮箱：sales@greatuv.com
