摘要:
An apparatus for providing a two-dimensional image of a three-dimensional object illuminates the surface of the object using an illumination source. Portions of the surface are imaged through an aperture in a plate onto a portion of a matrix sensor. The object is rotated about its principle axis while being simultaneously translated, and, at the same time the aperture is also rotated. By synchronizing these translational and rotational movements, successive portions of the object surface can image onto respective successive portions of the matrix sensor, thereby providing an improve two-dimensional image of the surface of the object.
