The 13th annual student conference took place from March 6 to 8, 2024. Master's students from technical disciplines at the University of Lübeck and Lübeck University of Applied Sciences presented their research results from projects, practical semesters and theses that they had carried out at universities, clinics, international research institutions and companies. These included numerous contributions from the Institute of Biomedical Optics.
Tjalfe Laedtke from Prof. Robert Huber's working group received the award for the "best oral presentation" at the conference. In his work at the BMO, Mr. Laedtke deals with the topic of "Angular Compounding" in optical coherence tomography.

Speckle noise in optical coherence tomography (OCT) arises due to the high coherence of the utilized light sources. This high contrast noise degrades image quality and limits the diagnostic potential. Angular compounding has been used as a method to decrease speckle noise without sacrificing resolution. It involves the acquisition of images from different angular viewpoints and combining them to obtain a speckle-reduced image. Our proposed method incorporates a robot to position an OCT probe at different angles, makes use of an optimization-based image registration technique to align images and constructs a fused image as an average of the registered angular images. The result is a speckle-reduced composite image with enhanced details. The robot allows images to be captured at many various angles, artificially increasing the numerical aperture. We present initial outcomes of our novel approach and outline the obstacles and potential advancements.
