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.
Development of a multi-scanner unit for MHz-OCT
AG Huber - Bachelor or Master Thesis
Modern optical coherence tomography (OCT) often uses beam deflection systems based on galvanometric scanners to capture three-dimensional data sets. These systems offer the advantage of simple integration, high precision and flexible scan patterns. However, they are limited to scanning speeds of a few kilohertz, which makes them unsuitable for fast MHz OCT systems. Resonant scanners, on the other hand, achieve scanning speeds of over 10 kHz, but operate at fixed frequencies and offer less flexibility in scan pattern design. A promising solution is the combination of a resonant scanner and two galvanometric scanners. This hybrid structure would enable the acquisition of numerous rapidly scanned sub-volumes and thus open up new possibilities for biomedical applications. For functional OCT imaging in particular, which is based on analysing repeated measurements over time, time windows ranging from minutes to a few microseconds could be covered in this way.
The aim of this work is to develop a multi-scanner unit consisting of a fast resonant scanner and two slow galvanometric scanners. These should be usable both individually and in combination for temporal multiscale OCT imaging. The work comprises the following steps:
- Simulation of the optical design
- Creation of CAD designs
- Installation and commissioning of the scanners
- Comprehensive characterisation of the beam paths
- Integration into an existing MHz-OCT system
- Systematic OCT measurements
No special prior knowledge is required, but a basic interest in technology is desirable. The work offers exciting insights into the fields of optics, CAD design and image processing programming and can be completed as part of a Master's thesis or in less depth as part of a Bachelor's thesis.
