Spectroscopy & Medical Engineering

The interaction of electromagnetic radiation with matter makes it possible to obtain information about a wide range of samples. Optical spectroscopy can be used to characterize substances in a wide variety of matrices (solid, liquid, heterogeneous) and to investigate and clarify photochemical or ageing processes, among other things. Both routine and high-end devices are available for optical spectroscopy in the areas of UV, VIS, NIR and IR. Combined with chemometric methods, changes in complex systems can also be characterized.

Project “OptiGebra”

Freezer burn is the drying out of frozen goods by sublimation, which starts on the surface and gradually moves deeper over time. In the “OptiGebra” project, an opto-sensory detection method was developed that can be used to quickly, safely

Projekt “DermPhoThera”

In the joint project “Dermatological narrowband UVB LED phototherapy with dosimetry”, GMBU e.V. processed the work packages for integrating UVB dosimetry and, together with an industrial partner, developed a hand-held device for UVB irradiation of psoriasis. The demonstrator consists

Spectroscopic diagnostics in medical engineering

Spectral diagnostics in medical engineering is based on the interaction of light with absorbers such as hemoglobin, melanin or water in the skin. In reflectance spectroscopy, broadband irradiation is used. This radiation is scattered and absorbed in the tissue

Project “DermUVSens”

The aim of the project cooperation with the Charité Berlin and the companies Silicann Systems GmbH and Courage+Khazaka electronic GmbH was to develop and test a combined UV-LED based fluorescence and remission spectrometer system for the reliable, point-by-point diagnosis

Project “Lignoscan”

In the research project “Quality measurement of coniferous logs – Lignoscan”, a prototype for the detection and assessment of red rot was developed and successfully tested in the sawmill together with experts from ThüringenForst and an SME based in

Projekt “PräziLan”

Das Projekt umfasst die Entwicklung und Erprobung eines aktiven Reflexionssensors zur Detektion der Nährstoffversorgung mit Phosphor, Kalium und Natrium bei Nutzpflanzen für die präzise Landwirtschaft.
