Iterative phase retrieval imaging based on variable wavefront curvature for biomedical imaging

Not Accessible

Your library or personal account may give you access

Abstract

Diffraction patterns with varying distance between illumination-source and the object are recorded. This has the same effect as changing the object sensor distance, with the advantage of preserving the resolution. Its usefulness for biomedical imaging, to assist the discrimination between tumorous and healthy tissue, is demonstrated.
