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.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
