  • Probe for measuring the thickness of frost accretion on a surface
    Patent number: 7719697
    Abstract: A probe for measuring the thickness of frost accretion on a surface includes a plurality of measuring stages that are stacked substantially orthogonally to the base of the probe. Each measuring stage has an emitter that emits a light beam that is substantially parallel to the base and a receiver that receives the light beam after reflection on the frost.

  • Probe For Measuring the Thickness of Frost Accretion on a Surface
    Publication number: 20080278733
    Abstract: The invention relates to a probe for measuring the thickness of frost accretion on a surface. According to the invention, the probe comprises a plurality of measuring stages (E1 to En) which are stacked at least substantially orthogonally to the base (2) of the probe and each measuring stage comprising at least one emitter which can emit a light beam that is at least substantially parallel to said base and at least one receiver which can receive said light beam after reflection on the frost.

  • Device for determining the values of at least one parameter of particles, especially of water droplets
    Patent number: 6813020
    Abstract: A device for determining the values of a parameter of particles, especially of water droplets, includes a measuring element having a measuring region that is intended to accommodate the particles. An illumination device illuminates the measuring region with a light beam, and an image acquisition device, having a camera, acquires an image of the measuring region illuminated by the illumination device. A processing device determines the values of the parameter from the image acquired by the camera. To determine the values of the parameter, the illumination device produces point illumination using a light beam whose light rays are focused on an objective optic of the image acquisition devices.
