Corrugated membranes for improved pattern definition with micro/nanostencil lithography

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart

We present a MEMS process for the fabrication of arbitrary (adaptable to specific aperture geometries) stabilization of silicon nitride membranes to be used as miniature shadow masks or (nano) stencils. Stabilization was realized by the fabrication of sili ...

New Approach for Simple and Rapid Shape Measurement of Objects with Surface Discontinuities

Sai Siva Gorthi

A new approach for unwrapping phase maps, obtained during the measurement of 3-D surfaces using sinusoidal structured light projection technique, is proposed. “Takeda’s method” is used to obtain the wrapped phase map. Proposed method of unwrapping makes us ...

Atlas-based segmentation of medical images locally constrained by level sets

Jean-Philippe Thiran, Valérie Duay, Nawal Houhou

Atlas-based segmentation has become a standard paradigm for exploiting prior knowledge in medical image segmentation. In this paper, we propose a method to exploit both the robustness of global registration techniques and the accuracy of a local registrati ...

Influence of the Vertical Profile of Reflectivity on Radar-Estimated Rain Rates at Short Time Steps

Alexis Berne

The present study aims to demonstrate the major influence of the vertical heterogeneity of rainfall on radar–rain gauge assessment. For this purpose, an experimental setup was deployed during the HYDROMET Integrated Radar Experiment (HIRE-98) based on a co ...

An Integral Approach to Phase Shifting Interferometry Using a Super-Resolution Frequency Estimation Method

Pramod Rastogi, Abhijit Patil, Rajesh Langoju

The objective of this paper is to describe an integral approach—based on the use of a super-resolution frequency estimation method—to phase shifting interferometry, starting from phase step estimation to phase evaluation at each point on the object surface ...

Synthetic displacers for preparative biochromatography

Jutta Christine Wandrey

A review discusses the principle of displacement chromatog., a chromatog. mode which has many advantages over conventional preparative elution chromatog., but which is handicapped by the lack of suitable displacers and stationary phases. [on SciFinder (R)] ...

Dispersion compensation for optical coherence tomography depth-scan signals by a numerical technique

Theo Lasser, Boris Clément Karamata

A new numerical a posteriori dispersion compensation technique for partial coherence interferometry and optical coherence tomography depth-scan signals is presented. This technique is based on numerical correlation of the depth-scan interferometer signal w ...

Analysis of phase measurements in combined interferometer and polarimeter systems

Roland Behn

Combined interferometer and polarimeter systems, using a single detecting element per line of sight, are susceptible to perturbation of the interferometric phase when modulation of the polarization vector is applied. This issue has been investigated extens ...
