Learning Adaptive Filtering in the Fourier Domain for Fringe Pattern Analysis: A New Reconstruction Paradigm in Digital Holographic Interferometry

open access: yesNanophotonics, Volume 15, Issue 20, 27 October 2026.
The object beam and the reference beam interfere at the camera sensor surface and multi‐angle tomographic recording based on off‐axis digital holography. ABSTRACT Single‐frame fringe pattern analysis in digital holographic interferometry (DHI) is essential for precision phase measurement under dynamic conditions. Recent advances in deep learning within

Reconfigurable Light Field Generation With Hologram‐Enhanced Multicore Fibers

open access: yesNanophotonics, Volume 15, Issue 20, 27 October 2026.
A novel metafiber platform enables reconfigurable generation of structured light patterns directly at the end of a multicore optical fiber. A 3D‐printed hologram maps individual fiber cores onto predefined image elements, allowing programmable pattern synthesis through selective core excitation.

Interferometric Near‐Field Scanning Optical Microscopy via Phase Conjugation of a Multimode Fiber Probe

open access: yesNanophotonics, Volume 15, Issue 20, 27 October 2026.
A multimode fiber probe collects far more of the near field than a single‐mode one, but scrambles the phase into speckle. Phase conjugation on a spatial light modulator restores the wavefront, concentrating the signal up to 165‐fold at a single detector pixel and recovering the full phase of propagating surface plasmon polaritons where conventional ...

Grading of glioma tumors using digital holographic microscopy

open access: yesHeliyon
Gliomas are the most common type of cerebral tumors; they occur with increasing incidence in the last decade and have a high rate of mortality. For efficient treatment, fast accurate diagnostic and grading of tumors are imperative. Presently, the grading
