Structured-Light 3D Imaging Based on Vector Iterative Fourier Transform Algorithm

Nanomaterials
Quasi-continuous-phase metasurfaces overcome the side effects imposed by high-order diffraction on imaging and can impart optical parameters such as amplitude, phase, polarization, and frequency to incident light at sub-wavelength scales with high ...

Simulation of superresolution holography for optical tweezers [PDF]

, 2008
Optical tweezers manipulate microscopic particles using foci of light beams. Their performance is therefore limited by diffraction. Using computer simulations of a model system, we investigate the application of superresolution holography for two ...

From laser ultrasonics to optical manipulation

Optics Express, 2015
During the interaction of a laser pulse with the surface of a solid object, the object always gains momentum. The delivered force impulse is manifested as propulsion. Initially, the motion of the object is composed of elastic waves that carry and redistribute the acquired momentum as they propagate and reflect within the solid.

A White Light Spectral Interferometric Demodulation Method Based on Frequency Domain Solving and Model Matching

IEEE Photonics Journal
White-light interferometry (WLI) is widely used for thin-film thickness metrology due to its non-destructive and high-speed characteristics. Yet conventional data-processing pipelines struggle to balance accuracy and computational efficiency.
