Numerical modeling and measurement by pulsed television holography of ultrasonic displacement maps in plates with through-thickness defects [PDF]
, 2010 We present a novel numerical modeling of ultrasonic Lamb and Rayleigh wave propagation and scattering by through-thickness defects like holes and slots in homogeneous plates, and its experimental verification in both near and far field by a self ...

Asynchronous Phase Shifts are Effective for Interferometric Single‐Molecule Localization Microscopy
Laser &Photonics Reviews, EarlyView.While interferometric Single‐Molecule Localization Microscopy (iSMLM) is well established to provide ultra‐high 3D precision, highly complex optical instrumentations are conventionally required for simultaneous multi‐phase interferometry. Here it is demonstrated that simultaneous multi‐phase interferometry is not essential for achieving ultra‐high ...

Two-wavelength digital holography through fog
Journal of the European Optical Society-Rapid Publications, 2023 Interferometric detection enables the acquisition of the amplitude and phase of the optical field. By making use of the synthetic wavelength as a computational construct arising from digital processing of two off-axis digital holograms, it is possible to

Enhancing Realism in Holographic Augmented Reality Displays Through Occlusion Handling
Laser &Photonics Reviews, EarlyView.The proposed optical‐see‐through holographic AR display with occlusion support presents highly realistic 3D AR scenes by projecting speckle‐suppressed, high‐contrast 3D holographic virtual images onto the corresponding real‐scene masks. By leveraging the occlusion capability, virtual shadows based on a Poisson distribution can also be rendered for the ...
