Wetting of anisotropic sinusoidal surfaces - experimental and numerical study of directional spreading [PDF]
, 2014 Directional wettability, i.e. variation of wetting properties depending on the surface orientation, can be achieved by anisotropic surface texturing. A new high precision process can produce homogeneous sinusoidal surfaces (in particular parallel grooves)

Full field phase imaging using a harmonically matched diffraction grating pair based homodyne quadrature interferometer [PDF]
, 2007 In this letter, the authors present a novel quadrature interferometry method based on the use of a harmonically matched shallow grating pair. Unlike a simple beam splitter or single shallow grating, the grating pair can confer a nontrivial interference ...

Nondestructive Profilometry of Optical Nanofibers [PDF]
Nano Letters, 2016 Single-mode optical nanofibres are a central component of a broad range of applications and emerging technologies. Their fabrication has been extensively studied over the past decade, but imaging of the final sub-micrometre products has been restricted to destructive or low-precision techniques.

Microsphere-assisted phase-shifting profilometry [PDF]
Applied Optics, 2017 In the present work, we have investigated the combination of a superresolution microsphere-assisted 2D imaging technique with low-coherence phase-shifting interference microscopy. The imaging performance of this technique is studied by numerical simulation in terms of the magnification and the lateral resolution as a function of the geometrical and ...

Computer-generated Moiré profilometry
Optics Express, 2017 A new 3D measuring method based on computer-generated moiré fringes is proposed. The two AC components of the 0-degree and 90-degree phase-shifted fringe patterns on reference plane are prepared in advance. While the AC component of the single-shot deformed pattern is multiplied by the two prepared AC components, respectively, two computer-generated ...
