Experts in the field of optical technology meet biennially at the "Laser – World of Photonics" in Munich. The Bonn research center caesar is exhibiting again at this year’s fair which will take place from 13 to 16 June. The research group "Holography and Laser Technology" headed by Prof. Peter Hering is presenting its state-of-the-art developments in Hall B2, Stand 252: an ultrafast holographic system featuring a mobile camera used for three-dimensional facial topometry for surgical planning and documentation as well as a particularly gentle laser technology for processing non-metallic substances.
In holographic three-dimensional facial topometry, a patient portrait hologram is generated using a short-pulsed laser and subsequently digitized. Thus a three-dimensional computer model is provided which can be visualized on every computer. A so-called texture with high resolution is retrieved from topometric information visualizing even skin pores and small hairs. The monochrome texture imposed on the model produces an extremely lifelike image. With the aid of computer tomography data models are retrieved demonstrating facial bone structure as well as the soft tissue on top. These images provide new options in oral or maxillo-facial surgical planning and documentation to achieve optimal functional as well as aesthetic results.
At the "Laser 2005" a mobile holographic camera system will be presented to the public for the first time. The mobile camera is assembled within 20 minutes and easy to operate. The camera enables flexible use at various locations and has been subject to clinical testing. At the "Laser" premiere on Monday morning (June 13th) a special "patient" will undergo holography: a thoroughbred award-winning poodle. On the one hand the extremely high resolution of the system is demonstrated as individual hairs of the poodle are visualized on the hologram and on the other hand the extremely short recording time, which leads to models free of motion-artifacts despite movements of the poodle.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
