Techniktagebuch Live Let's Play
Volker König, Kathrin Passig, Undine Löhfelm & André Spiegel
Nach dem Erfolg des kleinen Technikmuseums auf der #rp15 (Wir hatten ja nichts und das haben wir mitgebracht) machen wir dieses Jahr ein Live Let's Play vor Publikum. Die mühsamsten Logins, die umständlichsten Benutzeroberflächen, die dysfunktionalsten Free-WiFi-Vorschaltseiten, die kompliziertesten Newsletter-Abmeldungen – Autorinnen und Autoren des Technitagebuchs kennen sie alle und zeigen sie Live, in Farbe und mit ungespielter Verzweiflung.
A dream of computing and LaTeXing together
Manjusha Joshi
Researchers search for some computational package for their results. At the time when they have good output, they begin worrying about how to insert it in their LaTeX document. They have to keep track of their output, formatting and then insert it at the appropriate places in the document.
The SageTeX package is a blessing in these situations. It calls the powerful open source maths server Sage, to compute and embed the result into a...

Experimental research on DMD spatial light modulator and its multi-spectrum imaging
Yaotang Li
The fabric of digital micromirror device (DMD) and its operation are presented. Based on analyzing the electronic circuits and control signals of several types of commercial DLP projectors, the circuits of the projector that relate to warm-up, inter-locked protection, UHP lamp control and testing and color wheel control and detecting are successfully separated. After having simulated these control signals by a digital logic circuit experimentally and applied them to the main control board of the...
Applications of digital holography to measurements and optical characterization
Xinzhu Sang
With recent advances in computer and video capture technology, holographic films used in classical holography can be replaced with charged-coupled devices (CCD) and complementary metal–oxide–semiconductor (CMOS) image sensors to record and numerically reconstruct hologram, which is now known as digital holography. Digital holography introduces something very new to optical science. It eliminates the need for wet chemical processing and other time-consuming procedures, so recording and numerical reconstruction can be done in almost real time. It...
An old friend rediscovers holography
Karen Harvey
This talk will introduce HARMAN technology Ltd (formerly the silver halide manufacturing division of ILFORD Ltd) to the holographic community and launch its range of holographic products. In detail it will give an historical overview of our involvement in holography, recent results, the current applications of our technology, details of the science behind the product, and look ahead at the future for Holography at HARMAN. Ilford began manufacturing holographic products in the 1970’s with major...
A new photopolymer for volume holographic recording
Po-Lin Chen
Photopolymers have been applied in different applications on holographic recording. The advantages of this material are easy to synthesize, high refractive index change and high sensitivity. For volume holograms recorded with thick materials, good optical quality and dimensional stability of the recording material are the most stringent requirements. Recently, a novel technique for fabricating bulk phenanthrenequinone-doped poly(methyl methacrylate) (PQ:PMMA) photopolymers with thickness of ~cm has been developed in our laboratory1. According to our investigations, the...
\"Luminous Windows\" and \"Photons, Neurons and Bits\"

Holography for the 21st Century”. The event was a milestone for the MIT Museum, as well as for the field of holographic art. The exhibition showcased holography for the purpose of overcoming the material limits and hours of operation of the Museum and presenting a night exhibition of combined artistic and technical achievement that reached into the public space. “Luminous Windows”, that filled the Museum’s outdoor environment with light, color and virtual space through the...
Alte Säcke Politik
Wolfgang Gründinger
Die Debatte über Digitalisierung ist vor allem ein Risikodiskurs. Technische Spione lauern überall, große Konzerne attackieren die Privatsphäre, willkommen im Überwachungsstaat. Oft sind es diffuse Ängste alter Männer, die zwar die Digitalisierung nicht verstehen, aber die Debatte bestimmen.

Problems in Biological Imaging
Jelena KovacevicTechnology for Transparency
David Sasaki
"Transparency as a cure for the ills of modern democracy has become such a highly prized concept that the word was banned from use at Michigans Lake Superior State University due to mis-use, over-use, and general uselessness. Such lexical protests havent stopped hundreds of websites from popping up all over the world, grounded in the belief that making government information more accessible to ordinary citizens through sexy web 2.0 interfaces will lead to greater accountability...
WikiLeaks
Daniel Schmitt
Through its publications as the world’s only functioning whistleblowing platform, WikiLeaks has exposed corruption, political murder, torture as well as abuse of power on all continents.
But not only is WikiLeaks publishing the unpublished. Increasingly WikiLeaks has to preserve investigative stories that classic newsmedia cannot defend against those abusing legal systems in order to stiffle freedom of speech and supress critical voices.
According to the press, the platform has in its short existance produced more...
Upgrading political journalism
Lorenz Lorenz-Meyer
"Das Internet stellt dem professionellen politischen Journalismus mächtige neue Instrumente zur Verfügung. Zugleich relativiert es seine Bedeutung. Der Vortrag soll das positive Potential dieser Veränderungen ausloten und mögliche Schritte zu einer verbesserten politischen Öffentlichkeit skizzieren."
