Digital holographic microscopy for nanometric quality control of micro- optical components

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Jonas Kühn, Florian Charrière

In this paper, Digital Holographic Microscopy (DHM) is presented as a powerful tool for quality control of micro-optical components. It will be shown that not only the single-shot full field-of-view nanometer axial resolution makes DHM an ideal solution fo ...

Numerical Optics in Digital Holography

Christian Depeursinge, Tristan Colomb, Frédéric Montfort, Jonas Kühn, Florian Charrière

As digital holography achieves numerical reconstruction of the complex wavefront diffracted by specimen, a numerical optics formalism has been developed: numerical filters replace pinholes in Fourier planes, numerical lenses allow aberrations compensation ...

Ultra-thick micro-optical components using the PRISM photosensitive flexopolymer

Martinus Gijs, Abdeljalil Sayah, Virendra Kumar Parashar, Venkataragavalu Sivagnanam

We present the photosensitive flexopolymer PRISM as a new promising material for the realization of thick optical components. The PRISM flexopolymer can be directly polymerized using conventional UV exposure and is simply developed in a water-based solutio ...

Image-guided surgical microscope with mounted minitracker

Gaëtan Marti, Jaime Garcia Giraldez

A new image-guided microscope using augmented reality overlays has been developed. Unlike other systems, the novelty of our design consists in mounting a precise mini and low-cost tracker directly on the microscope to track the motion of the surgical tools ...

Automatic procedure for aberrations compensation in digital holographic microscopy

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Nicolas Aspert, Pierre Marquet, Jonas Kühn, Florian Charrière, Mihaela Marian

Digital Holographic Microscopy (DHM) is a powerful imaging technique allowing, from a single amplitude image (amplitude and phase), reflected acquisition (hologram), the reconstruction of the entire complex wave front by or transmitted through an object. B ...

Purely numerical compensation for microscope objective phase curvature in digital holographic microscopy: influence of digital phase mask position

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Pierre Marquet, Florian Charrière

Introducing a microscope objective in an interferometric setup induces a phase curvature on the resulting wavefront. In digital holography, the compensation of this curvature is often done by introducing an identical curvature in the reference arm and the ...

Automatic procedure for aberration compensation in digital holographic microscopy and applications to specimen shape compensation

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Nicolas Aspert, Pierre Marquet, Jonas Kühn, Florian Charrière

We present a procedure that compensates for phase aberrations in digital holographic microscopy by computing a polynomial phase mask directly from the hologram. The phase-mask parameters are computed automatically without knowledge of physical values such ...
