Implication

Methodological study demonstrates simultaneous phase and amplitude retrieval in homogeneous samples, highlighting a non-iterative solution to the in-line holographic twin-image problem.

Key Points

To develop and evaluate a direct, non-iterative mathematical method for simultaneously retrieving both phase and amplitude information from a single defocused transmission image.
Formulated a deterministic analytical reconstruction algorithm tailored to homogeneous objects under explicit transmission and defocus assumptions.
Validated the reconstruction method using experimental data acquired from an X-ray phase contrast ultramicroscope using point-projection geometry.
Successfully extracted phase and amplitude distributions simultaneously from a single defocused exposure without iterative convergence steps.
Resolved the twin-image artifact inherent to in-line holography, providing qualitative validation for broad application across X-ray, electron, neutron, and visible-light microscopy.
