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 formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
