Diffuse light transmittance of glass fiber-reinforced polymer laminates for multifunctional load-bearing structures

Thomas Keller, Anastasios Vassilopoulos, Andreas Schueler, André Gabriel Kostro, Julia De Castro San Roman Fest, Carlos Pascual Agullo

The diffuse light transmittance of hand lay-up glass fiber-reinforced polymer (GFRP) laminates was investigated. Spectrophotometric experiments were performed on unidirectional and cross-ply glass fiber-reinforced polymer specimens with fiber volume fracti ...

Automated Biomanipulation of Single Cells using Magnetic Microrobots

Mahmut Selman Sakar

Transport of individual cells or chemical payloads on a subcellular scale is an enabling tool for the study of cellular com- munication, cell migration, and other localized phenomena. We present a magnetically actuated robotic system capable of fully autom ...

Longitudinal-differential phase distribution near the focus of a high numerical aperture lens: Study of wavefront spacing and Gouy phase

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We present a longitudinal-differential (LD) phase distribution near the focus of a high numerical aperture (NA=0.9) aplanatic lens illuminated with a linearly polarized monochromatic plane wave. The Richards and Wolf method is used to compute field distrib ...

Multiple-Field Approach for Aberration Correction in Miniature Imaging Systems Based on Wafer-Level Production

Hans Peter Herzig, Toralf Scharf, Nicolas Bongard

IIn mobile imaging systems, the most difficult element to integrate is the objective lens. Here we present an intermediate approach between the costly traditional objectives and the low-resolution objectives inspired by the compound eyes of insects. Our mu ...

Empowering Low-Cost CMOS Cameras by Image Processing to Reach Comparable Results with Costly CCDs

Giovanni De Micheli, Sandro Carrara, Yusuf Leblebici, Gözen Köklü, Julien Michel Ghaye

Despite the huge research effort to improve the performance of the complementary metal oxide semiconductor (CMOS) image sensors, charge-coupled devices (CCDs) still dominate the cell biology-related conventional fluorescence microscopic imaging market wher ...

Submicron hollow spot generation by solid immersion lens and structured illumination

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We report on the experimental and numerical demonstration of immersed submicron-size hollow focused spots, generated by structuring the polarization state of an incident light beam impinging on a micro-size solid immersion lens (μ-SIL) made of SiO2. Such s ...

Advanced optical characterization of micro solid immersion lens

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We report on the advanced optical characterizations of microfabricated solid immersion lenses with 2-mu m diameter, operating at lambda = 642 nm. The main feature, the spot size reduction, has been investigated by applying a focused Gaussian beam of NA = 0 ...

Optical characterization of subwavelength-scale solid immersion lenses

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We present the fabrication and optical characterization of nano-scale solid immersion lenses (nano-SILs) with sizes down to a subwavelength range. Submicron-scale cylinders fabricated by electron-beam lithography (EBL) are thermally reflowed to form a sphe ...

High numerical aperture silicon collimating lens for mid-infrared quantum cascade lasers manufactured using wafer-level techniques

Hans Peter Herzig, Lubos Hvozdara, Pierre-Yves Baroni, Joab Di Francesco, Antoine Muller

We present an aspheric collimating lens for mid-infrared (4-14 µ) quantum cascade lasers. The lenses were etched into silicon by an inductively coupled plasma reactive ion etching system on wafer level. The high refractive index of silicon reduces the heig ...

A Psf-Based Approach To Biplane Calibration In 3D Super-Resolution Microscopy

Michaël Unser, Suliana Manley, Daniel Sage, Hagay Kirshner, Thomas Pengo

Super-resolution localization microscopy methods such as PALM and STORM have been shown to provide imaging with resolutions up to a few tens of nanometers while using relatively simple setups. Biplane PALM has extended the PALM technique to three-dimension ...
