The University of Applied Sciences, Jena has received a Federal Ministry of Education and Research (BMBF) grant for €799,558 to establish an Open Lab Framework for an AI-based interdomain OCT-Data analysis. The principal investigators are Prof. Dr. Dirk Schmalzried, Prof. Dr. Jens Bliedtner and Prof. Dr. Iwan Schie.

 Within the project 'OpenLab AI - OpenLab for Data Analysis and Applied AI' a cross-domain framework for the analysis and processing of optical tomographic image data will be developed, which can be used cross-domain for the investigation of material surfaces in the domain of manufacturing and quality assurance as well as in the domain of medicine, e.g. for investigations of skin and retina data. This framework is intended to be a basis for an interdisciplinary teaching in data competencies in almost all faculties of the University of Applied Science Jena. Through cooperation and networking with local industry (Carl-Zeiss Meditec), research institutes (Leibniz Institute of Photonic Technology, Jena), clinics (SRH Wald-Klinikum Gera), as well as local partner in science and translation (InfectoGnostics Campus, Medways, and SpectroNet) anonymized data sets will be made available as a basis for the training of young scientists and for scientific work as a result of the project.

 The project will transfer data processing approaches established in medical OCT-data analysis to OCT-data of cracks and surface damage of glasses. This interdisciplinary translation can directly address the upcoming problems of data analysis and automation in material processing and quality control. At the same time, model generation in biomedical imaging, through the uses of cross-domain data for specific analytical applications, e.g. SNR and resolution enhancement, will benefit from the cross-disciplinary approach. Thus, a framework for data processing and analysis of OCT image data will be developed that, as a result, can be used in optics manufacturing processes as well as in biomedical diagnostics and analysis.

Entitled "International and digital subsurface-damage-testing technologies laboratory", the OpenLab for OCT will be present with an Invited Talk at EOSAM22 in Porto on the 13th of Septmeber 2022 at 4:30pm :

With the establishment of a versatile infrastructure for subsurface damages, a new interational laboratory has been established. For this purpose, researchers from the fields of optical metrology, optics technology, ophthalmology and computer science joined forces. A central research question and object of object in the OpenLab are microcracks in optics production, so-called subsurface damage. With the ultra-high resolution and highly sensitive optical coherence coherence tomography, a measuring principle based on white light principle based on white light interferometry, it will be possible to in glasses and ceramics with a resolution of 1 μm. The laboratory is open to researchers and users to work together on topics related to SSD or to have measurement tasks carried out directly. The article presents the structure, the possibilities of cooperation and the goals of the open lab.

MT/BT students receive funding for the development of a low-cost and imaging OCT (optical coherence tomography) system for teaching and research


With their idea to develop a low-cost OCT system for teaching, the two master students Calvin Kreft and Konstantin Gramatte scored points with the members of the research committee. The funding is intended to promote student involvement in research and development at the Ernst Abbe University of Applied Sciences Jena (EAH Jena). To ensure that the two students do not lose their way, they are actively supported by Professor Dr. Iwan Schie.

 

Optical coherence tomography (OCT) is an imaging technique for generating two- and three-dimensional images of depth profiles in organic and non-organic media, similar to ultrasound imaging. Due to the high axial resolution of about 0.5 μm to 15 μm and a simultaneously relatively high penetration depth of 1-3 mm, depending on the wavelength used, this method offers a wide range of applications, including medicine and materials analysis. Ophthalmology in particular benefits from the technological advances of OCT due to the high-resolution imaging, for example in the examination of the anterior and posterior segment of the eye.

 

The project includes the development and setup of an OCT system, which explains the implementation of the imaging technique to students in a clear and practical way and enables a "hand-on experience" with this technique. This practical implementation opens up numerous possibilities in teaching for a practice-oriented university. These include the creation of numerous practical courses around this topic to deepen the basics of this imaging technique in medicine and materials analysis, as well as the practical use of 3D printers, which are gaining significant importance as time goes on.

 

Invitation to the 21st Colloquium on Manufacturing Technology and the Inauguration of a New Machining Center for Optics Production

 

Dear ladies and gentlemen, dear colleagues and students,

 

We would like to invite you to the 21st Colloquium on Production Engineering and the inauguration of a new machining center for optics production on July 27, 2022, from 2 to 6 pm in Lecture Hall 7 of our university.


The event will start with four presentations around precision machining of optical freeforms and their measurement. This will be followed by a live demonstration of the machining of a complex freeform, followed by the ceremonial commissioning of a new 6-axis polishing center.

The acquisition of this equipment was made possible by a grant from the Deutsche Forschungsgemeinschaft e.V. (DFG) and the Free State of Thuringia. This means that the machine equipment for the entire process chain of optics production of complex components and free forms is now available at our university. It offers extended possibilities for joint development projects and the integration of innovative manufacturing technologies into teaching.

At the end of the event, a joint meal with Thuringian specialties offers the opportunity to get into conversation, discuss ideas, network and exchange experiences.

For planning purposes, please register via our website: Manufacturing Technology Colloquium and Ceremonial Inauguration of a 6-Axis Polishing Center -Event (ag-bliedtner.de).

 

Best regards,

Marlies Patz & Jens Bliedtner
