The 3D beating dynamics of eukaryotic flagella drive motility, sensory functions, and resource acquisition, yet highly non‐planar beating patterns remain poorly characterized. Based on Digital Holographic Microscopy, holoV3C enables label‐free 3D reconstruction of such complex dynamics with 53 nm axial resolution, demonstrated on mouse sperm and ...

High‐Accuracy Thin‐Film Stress Sensor Exploiting Integrated Digital Image Correlation
A high‐accuracy Speckle Stress Sensor (SSS) is introduced for real‐time thin‐film stress measurements, combining integrated digital image correlation (IDIC) with dense overlapping spot patterns generated by a simple LED‐perforated plate setup. Unlike conventional multi‐beam optical stress sensors relying on detection of the centers of isolated laser ...

The reconstruction of digital holograms on a computational grid
Digital holography is greatly extending the range ofholography's applications and moving it from the lab into the field: a single CCD or other solid-state sensor can capture any number of holograms while numerical reconstruction within a computer ...

Terahertz Metasurface for Spatial Detection of Full Stokes Parameters and Polarization Imaging
This work presents a THz polarization analyzer with significantly improved robustness against nonuniformity. By integrating four polarization‐sensitive meta‐atoms into a meta‐cell, the metalens splits incident light into six polarization components and generates off‐axis focal spots.

Depth enhancement of optical scanning holography with a spiral phase plate [PDF]
A spiral phase plate is applied to the optical scanning holography system to improve the depth resolution of the reconstruction, the simulation results show that the depth interval can be resolved at a 0.4 mm with only a single hologram.

Terahertz Encryption With a Polarization‐Sensitive Metasurface
We propose a dual‐functional terahertz encryption metasurface that enables independent information retrieval in both the near field and the far field within a single device. In the near field, polarization‐selective amplitude modulation reveals textual patterns, whereas in the far field, phase engineering encodes multiple digital data in focal‐spot ...
