Nanoscale materials are nowadays widely used in many different modern technologies.
Special attention is thus required for their characterization in order to optimize fabrication …

The Abbe diffraction limit tells that the resolution of an imaging system is completely
determined by the numerical aperture (NA) for a coherent illumination wavelength. Here, a …

Fluorescence acquisition and image display over a high dynamic range is highly desirable.
However, the limited dynamic range of current photodetectors and imaging charge-coupled …

We present MetaHDR, which is a single-shot high-dynamic range (HDR) imaging and
sensing system using a multifunctional metasurface. The metasurface is capable of splitting …

Conventionally, high dynamic-range (HDR) imaging is based on taking two or more pictures
of the same scene with different exposure. However, due to a high-speed relative motion …

The emergence of micro-and nanotechnologies (in optics, electronics and mechanics) and
their recent progress, in terms of performance, miniaturization and quality, are largely due to …

The constructed high-dynamic-range image from merging standard low-dynamic-range
images with different camera exposures contains ghost-like artifacts caused by moving …

Applications in the field of product security and authentication to prevent counterfeiting rely
on abilities of microscale measurements of printed dots. Thus, researches described in this …

Functional materials are challenging to characterize because of the presence of small
structures and inhomogeneous materials. If interference microscopy was initially developed …

Ce manuscrit de thèse présente l'étude des techniques de super-résolution latérale en
nanoscopie optique, qui est une des nouvelles techniques d'imagerie haute résolution …
