Patent number: 9363484Abstract: A method for range imaging allows determining respective distances to multiple objects, based on a single image. The image is captured through a component having a transmittance function of which the Fourier transform is inscribed on a circle within a plane of spatial frequencies. A Fourier transform of the captured image is calculated in order to obtain a total spectrum for the image content. The distance to each object is then calculated based on several homothetic superimpositions of a reference spectrum with the total spectrum, so that said reference spectrum coincides with a portion of the total spectrum each time.Type: GrantFiled: August 21, 2013Date of Patent: June 7, 2016Assignee: ONERA (Office National d'Etudes et de Recherches Aerospatiales)Inventors: Martin Piponnier, Jerome Primot, Guillaume Druart, Nicolas Guerineau

Patent number: 8654348Abstract: The application relates to a method for analyzing the wave surface of a light beam from a source to the focus of a lens. The beam illuminates a sample on the analysis plane and having a defect. A diffraction grating of the plane is a conjugate of an analysis plane through a focal system. An image is formed in a plane at a distance from the grating plane and analyzed by processing means. The invention encodes this grating by a phase function resulting from the multiplication of two phase functions, a first exclusion function defining a meshing of useful zones transmitting the beam to be analyzed in the form of light pencil beams, and a second phase fundamental function which creates a phase opposition between two light pencil beams coming out of adjacent meshes of the exclusion grating.Type: GrantFiled: April 21, 2009Date of Patent: February 18, 2014Assignee: Office National d'Etudes et de Recherches Aerospatiales (Onera)Inventors: Jérôme Primot, Bruno Toulon, Nicolas Guérineau, Sabrina Velghe, Riad Haidar

Patent number: 7826066Abstract: A method and a system for analyzing the wavefront of a light beam, wherein a diffraction grating is arranged in a plane perpendicular to the light beam to be analyzed and optically conjugated to the analysis plane. Different emerging beams of the grating interfere to generate an image having deformations linked to the gradients of the wavefront to be analyzed. The method is characterized in that the grating carries out the multiplication of an intensity function which is implemented by a two-dimensional grating with hexagonal meshing of surface S transmitting the light of the beam to be analyzed into plural emerging beams arranged in a hexagonal meshing, by an phase function which is implemented by a two-dimensional grating with hexagonal meshing of surface 3S which introduces a phase shift close to 2?/3 (modulo 2?) between two adjacent secondary beams.Type: GrantFiled: July 17, 2008Date of Patent: November 2, 2010Assignee: ONERA (Office National d'Etudes et de Recherches Aerospatiales)Inventors: Jerome Primot, Nicolas Guerineau, Sabrina Velghe

Patent number: 6577403Abstract: In a process for analyzing the wavefront of a light beam, a diffraction grating with rectangular meshing is placed in a plane perpendicular to the light beam to be analyzed and optically conjugate with the analysis plane. Different emergent beams from the grating interfere to form an image whose deformations are related to the slopes of the wavefront analyzed. The grating multiplies an intensity function, implemented by a two-dimensional intensity grating, which defines a rectangular meshing of sub-pupils transmitting the light from the beam to be analyzed into a plurality of emergent beams disposed in accordance with a rectangular meshing, with a phase function implemented by a two-dimension phase grating which introduces a phase shift between two adjacent emergent beams such that the two emergent beams are in phase opposition.Type: GrantFiled: June 13, 2000Date of Patent: June 10, 2003Assignee: ONERA (Office National d'Etudes et de Recherches Aerospatiales)Inventors: Jérôme Primot, Nicolas Guerineau
