  • Patent number: 10458842
    Abstract: The detection circuit comprises a detector connected to an integration node. A bias circuit biases the detector between a first bias state and a second floating state. The potential of the integration node is at a target value when the bias circuit biases the detector to the first state and varies when the detector is in floating state. A measurement circuit without charge losses delivers a value representative of the potential present on the integration node N. A transfer circuit of the electric charges performs transfer of the electric charges from a stray capacitor of the photodiode to an integration capacitor. An output terminal delivers a voltage representative of the potential present on the second terminal of the first capacitor.

  • Patent number: 10401155
    Abstract: A method of inspecting a structure including a photonic material using a movable inspection apparatus includes irradiating a section of the structure, receiving radiation diffracted from a photonic material in the section of the structure, determining a deformation of the photonic material as a function of at least one of i) an intensity of the radiation received ii) a position of the radiation received and iii) a wavelength of the radiation received, and determining if a magnitude of the deformation is higher than a threshold. If the magnitude of the deformation is higher than the threshold data is stored concerning the deformation of the photonic material; contrarily, if the magnitude of the deformation is not higher than the threshold: the inspection at the location of the photonic material is stopped and the inspection apparatus is moved in order to inspect another section of the structure.

  • Patent number: 10365298
    Abstract: A detection arrangement and method for directing the sensitivity of an optical knife-edge detection system to its optimal operating point. This is referred to as an increase in the detection dynamic range of the system with advantageous applications for detecting motion of a surface such as for Atomic Force Microscopy as well as detecting acoustic vibrations on unstable surfaces. A pair of parallel reflecting surfaces, such as an optical slab waveguide, serve to reflect the sensing beam back onto the knife-edge detector once it is shifted off its sensing range. Allowing multiple reflections, the sensing beam is maintained on the knife-edge detector even at large angular offsets from the optimal operating point of the basic knife-edge detector. Use of a modified arrangement, with two knife-edge detectors at quadrature ensures near-optimal sensitivity at a detection dynamic range up to forty-fold larger than that of the basic knife-edge system.
