Patents by Inventor Stephane Bouillet

Stephane Bouillet has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9937674
    Abstract: A method for shaping an optical component so that it has an aspherical optical surface. In the method: the optical component is heated and mechanical stresses are applied thereto; heating and applying the mechanical stresses are stopped; an optical surface of the component is polished into a planar or spherical shape; and viscous elastic deformation of the optical component is relaxed. The method for example has applications in manufacturing aspheric mirrors having great dimensions.
    Type: Grant
    Filed: April 29, 2014
    Date of Patent: April 10, 2018
    Assignee: Commissariat à l'énergie atomique et aux énergies alternatives

  • Patent number: 9267789
    Abstract: A method for absolute measurement of flatness of surfaces of optical elements. In the method, an interferometer having a measurement axis is used for applying a three-flat method to three optical elements, by conducting actual measurements on the elements, surfaces of the elements are reconstructed by an iterative processing operation in which measurements are simulated and simulated measurements are compared with the actual measurements. At least two actual measurements are made after having performed a rotation around the measurement axis and/or a translation perpendicular to the measured axis, of a measured optical element relative to the other.

    Abstract: A method for absolute measurement of flatness of surfaces of optical elements. In the method, an interferometer having a measurement axis is used for applying a three-flat method by three optical elements, by conducting actual measurements on the elements, and planes of the elements are reconstructed by an iterative processing operation in which measurements are simulated and simulated measurements are compared with the actual measurements. At least two actual measurements are made after having performed a rotation around the measurement axis and/or a translation perpendicularly to the measured axis, of a measured optical element relatively to the other.
