The Hannover Centre for Optical Technologies HOT is an interdisciplinary research center of Leibniz University Hannover, Germany, and conducts research in applied optics and photonics. Conceptually, the center addresses all relevant aspects of light in a complex, highly functional optical system. The main directions pursued in the Roth group at HOT are medical optics and analytics, polymer photonics and integrated sensing, information and illumination technologies as well as micro- and nanooptics. Furthermore, the group develops hybrid optical simulations for light-matter interaction in biological materials. In the field of medical optics, the group works on systems for non-contact digital dermoscopy and polarimetry for inflammatory skin diseases, point of care sensing systems based on fiber-optics and plasmonics as well as multimodal devices for skin cancer screening and detection relying on imaging and spectroscopic techniques. The HOT is embedded in the infrastructure of the Leibniz University Hannover which is a member of the German TU9 German Universities of Technology in Germany.

Main role in the project
The LUH will contribute to the design and construction of the full body scanner including the integration of the opto-mechanical elements such as light sources, lenses, and cameras. It will be involved in the definition of the technical specifications and the protocols for testing and validation as well as the calibration concepts. Furthermore, the HOT is responsible for the development and operation of the illumination system which in combination with a tunable lens and a camera system will be emplyoed for automated skin imaging. A key aspect will be the achievable resolution of the system and the image focus control which needs to be setup and verified for this purpose. Ultimately, the system will be employed to obtain 3D images of the lesion under study with high resolution comparable to the one established with contact-dermoscopy. Finally, the HOT will be involved in the generation of the ground truth data required for validation of the system in close cooperation with the partners from hardware and software development and the clinical dermatologists.
