The emergence of quantum technologies, including cold atom-based accelerometers, offers an opportunity to improve the performances of space geodesy missions. In this context, CNES initiated an assessment study called GRICE (GRadiometrie a Interferome

Precision farming or agriculture (PA) is a concept where agricultural practices are modulated according to intra-field crop variability. Multispectral sensors have standing use in remote sensing, onboard aircraft and satellites for mapping biomass. W

Generating 3D depletion distribution in an achromatic single-channel monolithic system

Autor: Clément Fallet, Arvid Lindberg, Gabriel Y. Sirat

Publikováno v: SPIE Proceedings.

Recent developments have shown that conical diffraction by a biaxial crystal can create a vortex beam for use in 2D STED microscopy. It has been shown that this concept can be extended and also generate the depletion distributions used for 3D STED mi

A new method to achieve tens of nm axial super-localization based on conical diffraction PSF shaping

Publikováno v: SPIE Proceedings.

We present a method for Z-super-localization in fluorescence microscopy, based on conical diffraction. By using a thin biaxial crystal, the Point Spread Function (PSF) shape of an objective is made to depend strongly on the z coordinate. This z depen

Focusing by a high numerical aperture lens of distributions generated by conical diffraction

Autor: Sybille Rosset, Gabriel Y. Sirat, Clément Fallet

Publikováno v: Optics letters. 39(23)

This Letter examines the diffraction of a vortex beam by a high numerical aperture of topological charge ±1 generated by conical diffraction. Our research shows the behavior of the vortex beam is similar to the one already observed for Laguerre-Gaus
