  • Publication number: 20230348314
    Abstract: The invention relates to a process for inscribing a three-dimensional structure formed from variations in refractive index in the bulk of a transparent oxide glass comprising silver ions by femtosecond-laser-beam irradiation, the method comprising: generating a laser beam made up of a series of ultra-brief light pulses of pulse duration shorter than the characteristic time of thermalization of the glass so as to achieve an excitation at the point of irradiation via multi-photon interaction; focusing said beam at a desired depth in the glass; irradiating point by point the glass with said beam so as to form the structure in the glass along a predetermined path, the number of pulses, the repetition rate of the pulses and the irradiance at each irradiation point being controlled to induce an accumulation of silver aggregates localised in an annular peripheral region around an irradiation point, said accumulation of aggregates generating a variation in refractive index in the annular peripheral region around the

  • Patent number: 10580323
    Abstract: Disclosed is a hybrid simulator for teaching optics or for training adjustment of an optical device. The hybrid simulator includes at least one dummy optical component physically simulating an optical device, at least one actuator device for generating or simulating an adjustment of the dummy optical component, a sensor configured for detecting an adjustment signal representative of operating the actuator device, a digital processing system including a numerical model for simulating an output numerical optical beam resulting from interaction between an input numerical optical beam and a numerical optical component representing the optical device as a function of the adjustment signal and a display system for displaying a visual signal representative of the output optical beam and/or augmented reality signals.

  • Patent number: 8240805
    Abstract: The invention concerns a detection system (7) for measuring at least one characteristic of an inked zone (5) comprising at least one sensor adapted to sense a light radiation reflected by said inked zone (5) and to generate a measurement signal representing at least the characteristic of the inked zone (5). Such a system further comprises at least one first optic fiber (10), adapted to convey up to the neighborhood of the inked zone (5), a light radiation emitted by a light source (11).

  • Patent number: 7709798
    Abstract: This invention relates to a wide band optical gate in the terahertz domain (wavelengths in the far infrared). It comprises a first optical source (2) emitting a first beam (FTHz) in said terahertz domain, a first plate made of a semiconducting material (1) illuminated by said terahertz beam and a second optical source (3) emitting a second beam (FIR) at a wavelength capable of saturating the first plate (1) made of a semi-conducting material and making it reflective at terahertz wavelengths. This invention also relates to a system for measuring terahertz signals and to a terahertz generator. It is particularly applicable to systems for measuring terahertz signals and to terahertz generators.
