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.

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.
