PhD: Lensless 3D optical imaging

Work Activities

Computational optical imaging is a powerful tool to recover object structure from diffraction patterns without relying on conventional high-quality optics and microscope objectives. While many lensless approaches already work well for 2D imaging, achieving high-resolution volumetric reconstruction of complex structures in compact fiber-based format remains a major challenge.

In this project you will push the boundaries of optical microscopy and develop new approaches for 3D lensless imaging based on ptychography, structured illumination, fiber-based detection and physics-informed computational reconstruction. The work will combine optical experiments with algorithm development. On the experimental side, you will build and optimize ptychography setups using visible light, spatial light modulators, and multimode fibers. You will investigate optimized illumination and detection schemes that maximize informa...
