Correction of spherical surface measurements by confocal microscopy

Toralf Scharf, Wilfried Noell, Jeremy Béguelin

Refractive microlenses are nowadays widely used in optical systems. Characterizing their surface is essential to ensure their quality and to optimize their fabrication process. This is realized by optical surface profilers thanks to their vertical resoluti ...

Portable advanced off-axis camera for quantitative phase microscopy

Christian Depeursinge

We propose and experimentally demonstrate a device in which common-path interferometry combined with off-axis holographic geometry is used to realize a digital holographic camera which can be attached to the camera port of a conventional transmission micro ...

On-chip near-infrared optical spectrometer based on single-mode Epo waveguide and gold nanoantennas

Irène Antoinette Philipoussis, Toralf Scharf, Joab Di Francesco, Maurine Malak Karam Awadallah

We report about optical spectrometry using gold nanostructures printed on top of an integrated optical waveguide. The optical waveguide is a single-mode buried waveguide made from a combination of photo-polymerizable materials and is fabricated by photolit ...

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 ...

Optical reconstruction of transparent objects with phase-only SLMs

Christian Depeursinge, Yves Delacrétaz, Cristian Arfire

Three approaches for visualization of transparent micro-objects from holographic data using phase-only SLMs are described. The objects are silicon micro-lenses captured in the near infrared by means of digital holographic microscopy and a simulated weakly ...

Comparison of Two Cameras based on Single Photon Avalanche Diodes (SPADs) for Fluorescence Lifetime Imaging Application with Picosecond Resolution

Edoardo Charbon, Claudio Bruschini, Francesco Regazzoni, Samuel Burri, François Eric Powolny

We report on a comparative study of two time-resolved cameras based on digital Single Photon Avalanche Diodes (SPADs) for Fluorescen ce Lifetime Imaging applications. In contrast to standard imagers such as cameras, SPAD imagers provide intensity as well a ...

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 ...

Quantitative Comparison of Commercial CCD and Custom-Designed CMOS Camera for Biological Applications

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

In biological applications and systems where even the smallest details have a meaning, CCD cameras are mostly preferred and they hold most of the market share despite their high costs. In this paper, we propose a custom-designed CMOS camera to compete with ...
