Granted: 1983-04-15
Abstract: The present invention relates to a method of three-dimensional visualization of an object and a device therefor. A video camera, equipped with an image numerator takes photographs supplied by an electron microscope, for different angular positions of an object. The images which are numbered thus are applied to a digital image memory. Under the control of a visualization clock, this memory delivers the line of the same range taken successively in each of the base images to an image visualization member. The member reproduces its lines consecutively, and thus forms a composite image which may be used for relief visualization. In order to re-establish the format of the image, an anamorphosis is carried out, for example, by repeating n times on each line of the composite image each of the image points selected in one of the base images. The composite image which is obtained thus is provided with a lenticular grating of sectors of a cylinder.
