  • Fourier transform multi-channel spectral imager
    Patent number: 10677650
    Abstract: A spectral imager, including: a photodetector including a plurality of photosensitive sites exposed on a photosensitive surface; a collimating lens including an intermediate focal plane; an array of interferometers including two main waves, each including a cavity defined by two faces; an array of microlenses arranged in a plane parallel to the photosensitive surface, each microlens paired with an interferometer to form an optical pair, including an image focal plane coinciding with the photosensitive surface and facing a section of the photosensitive surface.

  • Contra-propagative wave spectograph
    Patent number: 7995211
    Abstract: The invention relates to a spectrograph (11) comprising a waveguide (10) provided with accesses (10; 10b, 12), a means for injecting two guided contra-propagative waves by each accesses in such a way that a spatial interference is formed in the waveguide, means (19, 20, 14, 16) for detecting the energy of the evanescent wave of the guided field produced by the interference of said contra-propagative waves.
    Type: Grant

    Date of Patent: August 9, 2011
    Assignee: Universite Joseph Fourier
    Inventors: Etienne Le Coarer, Pierre Benech, Pierre Kern, Gilles Lerondel, Sylvain Blaize, Alain Morand
  • Interferential spectroscopy detector and camera
    Patent number: 7812958
    Abstract: An interferential spectroscopy detector including a waveguide having an input side and a mirror on an opposite side, and means for detecting electromagnetic rays delivering an electric signal as a function of local intensity of an electromagnetic wave, detection being produced between an input side and the mirror.
