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.

Multimodal comparative study of different imaging systems

Master Thesis

In this master thesis, images of the same sample will be performed and compared for different tissue types using different imaging systems.

After an introduction, you will perform the measurements on the different devices yourself. The measurements will be preceded by the elaboration of an acquisition concept to reliably measure the same sample area in all systems.

The recorded data will be compared to find similarities/differences between the recordings of the individual systems. Depending on the progress of the work, first evaluation attempts with multivariate analysis methods and artificial intelligence will be carried out.

If you are interested, please contact: Hubertus Hakert

MHz-OCT for novel contrast of tissue images

Master Thesis | Internship (Master)

Recently, a new type of tissue contrasting was demonstrated based on optical coherence tomography (OCT) systems, the so-called "dynamic OCT (dOCT)". Here, the contrast is not generated by inherent structural contrast due to scattering or absorption, as in ordinary imaging, but is based on a statistical evaluation of the individual image elements and their behavior over time. For this so-called "dynamic contrast" primarily very high-resolution so-called optical coherence microscopy (OCM) systems were used, which made it possible to resolve subcellular structures in vivo. Since these systems usually have imaging rates well below one MHz, it would be of great benefit to use fast multi-MHz OCT systems based on FDML lasers. However, these systems usually exhibit a slightly lower axial resolution. Based on promising initial test measurements, dynamic contrast can also be generated using fast MHz-OCT. However, further research is needed to explore the possibilities of this approach in more detail.

The aim of this work is to evaluate the potential but also the limitations of dynamic contrast using MHz-OCT by means of systematic measurements and their evaluation. No special knowledge is required, but in any case, there should be a high interest in optical imaging, working with animal tissue samples and basic programming skills. Initial experience in OCT imaging is desirable but is not mandatory. The topic is particularly suitable as a project internship followed by a master's thesis.
