IGF via AiF: "HoloScope"

Needle-shaped lensless holographic endoscope

Thin and flexible endoscopes for minimally invasive medical diagnostics and therapies have only allowed 2D imaging so far, while endoscopes for 3D imaging have a cross-section too large for minimally invasive procedures. The aim of the "HoloScope" project is therefore to develop and validate a small-diameter endoscope (< 300 µm) that allows 3D imaging with subcellular resolution and is thus suitable for minimally invasive procedures. For this purpose, the scientists of the Laser Components and Fibres group will develop special fibre bundles with aperiodic core structure. New measurement and evaluation techniques, which will be developed and validated at the BIOLAS centre of excellence at Dresden University of Technology, will enable applications of these lensless fibre bundles for 3D imaging in the brain, for example.

The IGF project no. 21802 BG is funded by the Federal Ministry for Economic Affairs and Energy based on a resolution of the German Bundestag.
