We are always looking for interested students to join our team!
The main focus of our group is the technological development of optical imaging systems. The spectrum ranges from the design of fiber lasers to the development of electronic circuits and the implementation of our imaging techniques in clinical prototype systems.
Offers for Students
In our group there are almost always ideas or smaller projects that can be worked out in the context of a bachelor thesis, an internship or as a working student. For more advanced students we are also happy to offer master thesis topics. Our current topics for student theses and topics of other BMO working groups can be found below. The concrete questions can be elaborated in a personal conversation.
Offers for graduates
For our projects we are also regularly looking for new graduate students. A general requirement is a diploma or master degree (or equivalent).
If there are currently no suitable positions advertised for you, but you would still like to work in the group, please contact us. We are sure to find a solution for particularly motivated and interested students.
Robert Huber will gladly be your contact person. If you already know someone in the group or if you prefer to talk informally with a PhD student first, you can find the contact details of the group members here.
Measurement setup for determining the refractive index using a refractometer
AG Huber - Bachelor Thesis
The refractive index is a characteristic property of a medium and depends on the wavelength of the light (dispersion). With a refractometer the refractive index can be measure. However, with a refractometer, the refractive index of a medium can only be determined for a broad spectrum in the visible range.
In this work, a refractometer is to be extended by a device that allows the sample to be illuminated with different discrete wavelengths. The aim is to determine the refractive index of a medium at a specific wavelength. In addition, a holder for a SWIR camera is to be developed with which refractive indices in the infrared can also be determined. The tasks include the selection of different light sources, the 3D printing of mounts for the light source and camera and the determination of the refractive index of different media. No special prerequisites are required, but a high degree of personal responsibility and interest is assumed.

Characterisation of the OCT signal processing chain using artificial signals
AG Huber - Internship/Master Thesis
In optical coherence tomography (OCT), the optical interference signal passes through a large number of detection and processing steps before it is displayed as an image. Each of these individual steps makes a decisive contribution to image quality. This makes it all the more important to ensure an error-free sequence and to characterise the individual steps. Characterisation is difficult with "real" OCT signals with many degrees of freedom.
In this project, artificial OCT signals are to be generated using an arbitrary wave generator (AWG) and the processing chain from detection to image visualisation is to be evaluated. The tasks include, for example, programming arbitrary functions for the AWG, setting up a measurement setup consisting of AWG, OCT and real-time oscilloscope, calibrating the process steps or documenting the measurement results. No special prerequisites are required, but a high degree of personal responsibility and interest is assumed. Previous knowledge of signal processing, programming in Python or C or numerics is an advantage. The work will be carried out in close co-operation with a research assistant
