In coherent lens-less microscopic imaging, a major challenge is the phase problem, where detectors capture only intensity, losing critical phase information. This complicates the reconstruction of sharp, artifact-free images from holograms.
Traditional solutions often require multiple acquisitions or strong constraints like spatial support, making them impractical for time-sensitive in situ studies, such as tracking Mg implant degradation in real-time.
Now, two innovative approaches offer breakthroughs in artifact reduction and autofocus precision: PGD-based reconstruction enhances single-hologram image retrieval, and Model-matching autofocus refines Fresnel number estimation for sharper images.
Holographic imaging meets innovation! A PGD-based method reduces artifacts, while model-matching autofocus enhances precision, both tested at PETRA III @DESYnews, Hamburg.
