In cooperation with the Max Planck School of Photonics, the Lichtwerkstatt is developing digital teaching content with virtual reality (VR) and augmented reality (AR). For example, we are testing how laboratories can be enriched as real environments with digital information (AR) or how students can experience and learn the basics of experimental setup in the laboratory completely virtually (VR). In addition to the latest AR and VR glasses and powerful computers, the Lichtwerkstatt also has access to high-quality camera and recording technology for development and implementation. www.maxplanckschools.deExternal link

The UC2 project is creating an open-source, modular system that can be easily adapted to the user’s specific requirements. For example, optical and microscopy systems can be designed with ease. Production costs are low, as the individual components are manufactured using 3D printing or inexpensive, readily available mechano-electro-optical components are used. Image acquisition and processing are realized by ubiquitous systems such as smartphones or Raspberry Pi and deliver high-resolution results. 2022 the team founded a company to push open source microscopy even further. www.openuc2.com/External link

The Jena-based company aura optik studied the effect of focused laser light on various materials in the light workshop. The experimental approach consists of using a green laser pulsed in the nanosecond range and applying single (or a few) pulses to the samples. The samples are then examined by light microscopy and electron microscopy. The aim of this study is to find new approaches to microstructuring with lasers. 

The BMBF-funded research project “maQuer.SPACE” has been working closely with the Lichtwerkstatt to develop practical experiments on quantum photonics and teaching materials for the interested public. The aim was to bring quantum technologies closer to as many people as possible and make them understandable. The challenge for the team is to construct the components in such a way that an experimental setup can be replicated at home or in the classroom using inexpensive materials and typical tools in a DIY manner. The single photon detector based on an electrically operated avalanche photodiode is currently being developed by dedicated makers in the light workshop. They not only have low-cost, high-intensity and robust single-photon sources at their disposal, but also low-cost control electronics for the self-assembly of single-photon detectors.

The project NeoVital has been developing a sensor that uses nano-optical filters and 3D measurement technology to record the vital parameters of newborn babies, for example. Heart rate, blood oxygen content or respiratory volume can thus be monitored wirelessly. Researchers from Friedrich Schiller University Jena, Ilmenau University of Technology and Jena University Hospital are working on the project together with Steinbeis Qualitätssicherung und Bildverarbeitung GmbH. Parts of the prototype are being developed in the Jena Light Workshop. For example, the 3D printers are used to build the housing. In 2020, the project channeled into a Jena-based start-up and was awarded several prizes for innovation and entrepreneurship.

Physical computing is simply more fun than dry programming on a computer. The aim of the student project is therefore to develop a moving robot platform that can be connected to a variety of sensors. It is controlled via Raspberry Pi, which can be easily configured for the respective control and communication tasks. A self-propelled robot is the hardware basis. The platform is suitable both for beginners to learn how to program graphical programming languages and for experienced programmers to implement unusual sensors or actuators and work on more complex problems.

Calisto is a new type of integrated lighting and loudspeaker system with gesture-controlled operation. To this end, the Lichtwerkstatt was researching the use of suitable optical 3D sensor technology and developing customized evaluation software that supplements and simplifies 3D gesture control with context-related information. A central role in the concept is played by the targeted modeling of the lighting function with a planar radiation inspired by the sun.

Our collaboration partner Fraunhofer IOF developed an easily accessible development kit for flexible low-cost 3D sensor technology with pattern projection in the Jena Light Workshop. The scientists are supporting the maker community in applying this kit in innovative prototypes. Commercially available systems such as cell phones or tablets are used as a carrier platform for data acquisition and utilization. The necessary software is made available to the maker community for use and further development via the respective app stores.

Using structure-for-motion calculations in photogrammetry, object dimensions and 3D models can be created from ordinary video footage. To record the video material, large drones with GPS control usually fly over an easily accessible area. A project in the Light Workshop is investigating photogrammetry applications of small and agile FPV racing drones that carry a 360° camera. The special remote control concept makes it possible to navigate through areas that are difficult to access and unsuitable for GPS, of which a true-to-scale 3D model can then be calculated.

Celerrime is a fully functional drone that can be modularly adapted to different areas of application and can carry transport material and measurement technology. By combining modern sensor technology and artificial intelligence, the drone is intended to be used both by rescue teams in the search for and initial treatment of accident victims and as a high-altitude research platform for specific measurements.

In the innovation project supported by Fraunhofer IOF, fully documented instructions for the construction of a Raman spectrometer are being developed. The main challenge is that all individual parts are either readily available commercially or can be reproduced using 3D printing or other established manufacturing techniques. The aim is to produce a portable and cost-effective instrument that is suitable for simple measurement tasks.

In order to be able to calculate the trajectory of meteorites from image data, a network of several cameras is required that observe and record the night sky from different locations. The cameras must not only be weatherproof, but also have GPS, algorithms for image recognition or a data upload function. The aim of the project is to design a camera that meets all practical requirements and can be easily replicated in order to expand the network in the spirit of citizen science. The project is being developed in collaboration with abantu Kulturlabor Jena. And the project is a winner of the “Jugend forscht – Schüler experimentieren 2019” competition.

The aim of the project is to demonstrate alternative imaging systems with applications in hyperspectral imaging and 3D measurement. To this end, the team is analyzing various concepts of single-pixel cameras and supplementing them with detectors for exotic wavelengths, multispectral sensors and even complete spectrometers. A conventional scanner is used for the imaging system, which is enhanced with DMD array systems and compressed sensing methods. The team is receiving funding for the implementation from the Fraunhofer IOF. 

In the “Jugend forscht” project, students from Weimar are investigating the behavior of so-called Grätzel cells – solar cells that can be produced from plant dyes (antocyanins). To do this, hibiscus flowers are carefully boiled and processed. The self-produced cells are then professionally examined in the Jena Light Workshop using a solar simulator, which provides the same light output and spectrum as the sun. The project is supervised by the Gera Student Research Center.
