ABSTRACT:
A master disk is positioned such that a radial portion thereof is within a restricted field having good imagery of an optical projection system. A second blank disk is positioned such that the image location extends along a radial portion thereof. As the two disks are rotated synchronously a pattern in an annular area is formed on the blank disk replicating the master. Good imagery of the pattern is obtained with a simple system having an image field less than the size of the object being reproduced.
