1. An automatic dimension analyzer comprising:

  • a power driven table on which an object under measurement is placed, the table being movable in orthogonal directions in a field defined by a pair of coordinate axes;

    an optical system for forming an optical image of said object in a sample point field;

    means for scanning said sample point field in a rectangular raster format to produce sample point data bits each representing a sample point having a predetermined optical level;

    means for detecting a coincidence between at least one sample point data bit and a cursor defined in said sample point field parallel with one of said coordinate axes, said cursor being movable in said sample point field;

    a memory;

    data entry means for storing measurement instructions in sequentially addressable locations of said memory;
