Adaptive optics in speckle interferometry and in super-resolution

This thesis describes innovative techniques for reducing speckle noise and improving the intensity profile of the speckle correlation fringes. The methods are based on reducing the range of the modulation intensity values of the speckle interference patter ...

Adaptive optics using a liquid crystal spatial light modulator for ultrahigh-resolution optical coherence tomography

Rainer Leitgeb

Three-dimensional ultrahigh resolution optical coherence tomography (UHR OCT) and adaptive optics (AO) are combined using a liquid crystal programmable phase modulator (PPM) as a correcting device for the first time. AO is required for correcting ocular ab ...

Reflectance and transmittance model for recto-verso halftone prints

Roger Hersch, Mathieu Hébert

We propose a spectral prediction model for predicting the reflectance and transmittance of recto-verso halftone prints. A recto-verso halftone print is modeled as a diffusing substrate surrounded by two inked interfaces in contact with air (or with another ...

White beam x-ray waveguide optics

We report a white beam x-ray waveguide (WG) experiment. A resonant beam coupler x-ray waveguide (RBC) is used simultaneously as a broad bandpass (or multibandpass) monochromator and as a beam compressor. We show that, depending on the geometrical propertie ...

Resonator stability subject to dynamic random-tilt aberration

Theo Lasser, Max-Olivier Hongler

We derive the behavior of the average exit time (i.e., the number of reflections before escape) of a ray path traveling between two perfect mirrors subject to dynamic random-tilt aberrations. Our calculation is performed in the paraxial approximation. When ...
