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 ...

Full polarization optical profilometry [PDF]
Journal of the Optical Society of America A, 2012 Optical digital tomographic microscopy can be used for profilometry. The profile of the surface can be estimated from measurements of the complex diffracted far field obtained when the sample is illuminated successively under various incidences. Outside the validity domain of perturbative theories of diffraction, the profile is determined by using an ...

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 ...
