    摘要： A method for analysis includes directing a converging beam of X-rays toward a surface of a sample having multiple single-crystal layers, including at least a first layer and a second layer that is formed over and tilted relative to the first layer. The X-rays that are diffracted from each of the first and second layers are sensed simultaneously while resolving the sensed X-rays as a function of angle so as to generate a diffraction spectrum including at least a first diffraction peak due to the first layer and a second diffraction peak due to the second layer. The diffraction spectrum is analyzed so as to identify a characteristic of at least the second layer.

    摘要： An optical 3D digitizer with an enlarged non-ambiguity zone, comprising a structured light projector for projecting a fringe pattern over a target area, the fringe pattern having a shiftable position over the target area is disclosed. First and second cameras having overlapping measurement fields are directed toward the target area and positioned with respect to the projector to define distinct triangulation planes therewith. The second camera has a larger non-ambiguity depth than the first camera. A computer evaluates a same set of camera-projector related functions from images captured by the cameras including the projected pattern at shifted positions, builds low depth resolution and degenerated 3D models from the camera-projector related functions evaluated with respect to the second and first cameras respectively, determines chromatic texture from the images, and builds a complete textured 3D model from data corresponding between the low depth resolution and degenerated 3D models within a tolerance range.
