A universal fluid cell for the imaging of biological specimens in the atomic force microscope

Giovanni Dietler, Sandor Kasas, Giovanni Longo, Charles Roduit, Livan Bladimir Alonso Sarduy, Bhaskar Saha

Recently, atomic force microscope (AFM) manufacturers have begun producing instruments specifically designed to image biological specimens. In most instances, they are integrated with an inverted optical microscope, which permits concurrent optical and AFM ...

Reinforced and Post-tensioned Glass Beams

Pieter Christian Louter

This paper investigates the structural performance of reinforced and post-tensioned glass beams. This is done through bending tests on 1.5 m reinforced, post-tensioned and reference glass beam specimens. From the results it is observed that both reinforcin ...

Longitudinal-differential interferometry: direct imaging of axial superluminal phase propagation

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We introduce and demonstrate a new interferometric method called longitudinal-differential (LD) interferometry, which measures the spatially resolved phase difference of the scattered field by an object relative to the illumination. This method is combined ...

Differential Phase-Contrast X-Ray Computed Tomography: From Model Discretization To Image Reconstruction

Michaël Unser, Masih Nilchian

Our contribution in this paper is two fold. First, we propose a novel discretization of the forward model for differential phase-contrast imaging that uses B-spline basis functions. The approach yields a fast and accurate algorithm for implementing the for ...

Resolution and Complex Deconvolution in Holographic Microscopy

Yann Jérôme Michel Pascal Cotte

Interest in high resolution imaging techniques has recently multiplied due to their importance in bio-medical research. Quantitative phase measurements by holographic microscopy is an extraordinary tool to gain new understanding of transparent biological s ...

On the Characteristics of Highly Confined Light Fields

Myun Sik Kim

The Investigation of highly confined light fields created by different mechanisms, such as refraction, diffraction, and scattering, are the main subject of this thesis. We distinguish a specific scattering phenomenon of dielectric microspheres from general ...

Beyond the lateral resolution limit by phase imaging

Christian Depeursinge, Muhammed Fatih Toy, Yann Jérôme Michel Pascal Cotte

We present a theory to extend the classical Abbe resolution limit by introducing a spatially varying phase into the illumination beam of a phase imaging system. It allows measuring lateral and axial distance differences between point sources to a higher ac ...

Angle-and polarization-dependent collective excitation of plasmonic nanoarrays for surface enhanced infrared spectroscopy

Hatice Altug, Shyamsunder Erramilli, Kai Chen

Our recent work has showed that diffractively coupled nanoplasmonic arrays for Fourier transform infrared (FTIR) microspectroscopy can enhance the Amide I protein vibrational stretch by up to 10(5) times as compared to plain substrates. In this work we con ...

Quantitative phase restoration by direct inversion using the optical transfer function

Christian Depeursinge, Pierre Marquet, Shanshan Kou, Laura Waller

Quantitative phase recovery of phase objects is achieved by a direct inversion using the defocused weak object transfer function. The presented method is noniterative and is based on partially coherent principles. It also takes into account the optical pro ...
