ABSTRACT:
There is provided a device and a method for the formation of a high-resolution image of a 3-dimensional object. The surface of the object is scanned stepwise by a linear detector matrix, so that the entire height of the object is covered. The arrangement is such that each horizontal "slice" is in focus, for the specific altitude of the "slice", and the information is fed to an image selector which evaluates the video images, selecting the "in focus" information, and using this for the construction of the image. The system is based on a plurality of linear CCD detector arrays, which are used for scanning the surface of the object, the image selections mechanism and the mechanism for thus constructing the desired image.
