Journal ArticleDOI
Extended Hartmann test based on the pseudoguiding property of a Hartmann mask completed by a phase chessboard
Jérôme Primot,Nicolas Guérineau +1 more
TL;DR: A pseudoguiding of the energy issuing from this mask, allowing for an increase in the sensitivity of the Hartmann test is obtained, and a comparison between classical and new Hartmanngrams is presented.
Journal ArticleDOI
Wave-front reconstruction from multidirectional phase derivatives generated by multilateral shearing interferometers
TL;DR: This work proposes to exploit the natural capability of multiple lateral shearing interferometers to measure simultaneously more than two orthogonal phase derivatives and describes a method, based on Fourier-transform analysis, that uses this multiple information to reconstruct the wave-front under study.
Journal ArticleDOI
Free-standing subwavelength metallic gratings for snapshot multispectral imaging
Riad Haïdar,Grégory Vincent,Stéphane Collin,Nathalie Bardou,Nicolas Guérineau,Joël Deschamps,Jean-Luc Pelouard +6 more
TL;DR: In this article, a mosaic of ten spectral filters has been fabricated in a single 20"mm2 membrane drilled by nanoslits and coated by a gold layer, which is used to demonstrate real-time spectral imaging in a multichannel camera.
Journal ArticleDOI
Generation of achromatic and propagation-invariant spot arrays by use of continuously self-imaging gratings.
TL;DR: It is shown that a good CSIG approximation can be realized by a two-level phase grating that is experimentally tested.
Journal ArticleDOI
Effect of finite pixel size on optical coupling in QWIPs
TL;DR: In this paper, the optical coupling in quantum well photodetectors was investigated and it was shown that optical coupling efficiency is strongly dependent on the pixel size and that in very small detectors diffraction dominates the grating coupling.
