Patent Images

1. A method for generating and using information by radiation scanning an image, said method comprising:

  • a) generating a radiation beam,b) directing said radiation beam at an object including a specific image area containing different radiation reflecting marks, the marks being located along a scanning path of said image area,c) causing said radiation beam to scan said image area in a manner whereby said beam will intersect and be variably reflected by said different radiation reflecting marks,d) sensing the radiation reflected from said different radiation reflecting marks with radiation detection means,e) generating an electrical signal on the output of said radiation detection means, which signal varies in accordance with variations in the intensity of the reflected radiation,f) computer processing said varying signal and generating digital electrical signals defining characteristics of said different radiation reflecting marks of said specific image area scanned by said beam,g) recording said digital electrical signals in memory means,h) reproducing said digital electrical signals from said memory means, p1 i) computer analyzing said digital electrical signals and generating further electrical signals, andj) employing said further electrical signals to intelligibly indicate information relating to the different radiation reflecting marks of said specific image area scanned by said radiation beam.
