Tailored Light

Licht- und Beleuchtungstechnik prägt unseren Alltag. Angefangen von einfachen Beleuchtungskonzepten, über intelligente Lichtsysteme bis hin zu hochauflösenden Displays, in jedem Bereich spielt Licht eine entscheidende Rolle. Auf der Suche nach neuartigen Konzepten wurde ein neues Doktoranden-Programm ins Leben gerufen. Gemeinsam forschen das Hannoversche  Zentrum für Optische Technologien der Leibniz Universität Hannover sowie die Hochschule Hannover, das Laser Zentrum Hannover, die HAWK Hildesheim/ Holzminden/ Göttingen, die TU Braunschweig und die TU Clausthal an neuartigen Methoden zu diversen Themen rund um das Thema Licht.

Imaging in scattering media

Leitung:

Dr.-Ing. Maik Rahlves, Prof. Dr. Bernhard Roth

Förderung durch:

Lower Saxony Ministry for Science and Culture (MWK)

Kurzbeschreibung:

Due to the effects of strong scattering, imaging in complex media such as biological tissue remains one of the great challenges of modern optics. Recent studies have shown that these effects may be compensated by spatially manipulating the light´s wavefront with active optical devices. This project aims to apply wavefront-shaping techniques to established imaging methods to enhance imaging performance and penetration depth in strongly scattering samples.

Förderung durch:

Lower Saxony Ministry for Science and Culture (MWK)

Kurzbeschreibung:

Recent developments in illumination technologies in automotive industry are heading towards use of coherent light sources, because incoherent light is poorly formable. Numerous amount of work has been done in order to incorporate laser based illumination sources for headlamps, but rear end illumination is still under investigation. With the use of laser as illumination source, utilization of diffractive optical elements (DOEs) to diffract the illuminating laser beam in a predefined intensity distribution can be possible.

Non-contact dermatoscope for detection and examination of suspicious skin lesions

of suspicious skin lesions

Leitung:

Prof. Dr. Bernhard Roth, Dr. rer. nat. Merve Wollweber, Prof. Dr. Uwe Morgner

Bearbeitung:

M.Sc. Dierk Fricke

Kurzbeschreibung:

The standard method for the examination of skin lesions is contact dermoscopy . With the contemporary contact-type dermoscopes, lesions have to be scanned manually by imaging each lesion in direct contact with the skin. Although established this procedure has several drawbacks as it is time consuming, has poor reproducibility, and may even be painful for the patient. A non-contact remote dermoscope can overcome these drawbacks and furthermore allow automatized screening protocols. Thus, this project revolves about the development of a non-contact dermoscope for detection and examination of suspicious skin lesions.
