    摘要： A device and method for three-dimensional reconstruction of a scene by image analysis is provided. This device comprises an image acquisition device to capture images of the scene, an analysis device to calculate a three-dimensional reconstruction of the scene from at least one image of the scene taken by the image acquisition device, and a projection device to project a first light pattern and a second light pattern, which are complementary, on the examined scene, the first light pattern and the second light pattern being projected along separate projection axes forming a non-zero angle between them, so as to be superimposed while forming a uniform image with homogenous intensity in a projection plane.

    摘要： An ultrasonic probe for examining an object with ultrasound and a corresponding examination method are provided. The probe includes a plurality of emitter elements able to emit ultrasonic waves for emitting a focused ultrasonic beam into the object through an active area of a surface of the object, and a profilometer for determining the profile of the surface of the object and for controlling the emission of the ultrasonic beam depending on the determined profile. The profilometer includes an image-taking apparatus for taking at least one digital image of the active area and an image processing module able to determine the profile of the active area by analyzing the optical blurring of the or at least one image.
