1. In a system for optically scanning the surface of an object and comprising an optical scanning device for repetitively generating representations of visually perceptible information of a portion of the object, each representation of visually perceptible information comprising a single row of pixel digits, and for each such representation of visually perceptible information for generating representations of movement of said scanning device over the object, said movement representations comprising a first X-direction movement representation, a first Y-direction movement representation, said Y-direction being normal to said X-direction and a representation of second Y-direction movement of a point on said scanning device separate from the point of said first Y-direction movement representation, a method comprising:

  • determining from said representation of first X-direction movement and said representation of first Y-direction movement a position value;

    determining from said representation a first Y-direction movement and said representation of second Y-direction movement a rotation value indicative of scanning device rotation;

    determining, from said position value and said rotation value, a storage location in a two-dimensional pixel array for a first of said pixel digits and a last of said pixel digits of the representation of visually perceptible information; and

    writing into said two-dimensional pixel array said plurality of pixel digits in an approximation of a straight line between the storage location of the first pixel digit and the storage location of the last pixel digit.
