  • Method and apparatus for measuring the diameter of a running elongate object such as an optical fiber
    Patent number: 4847509
    Abstract: The diameter of a running elongate object such as an optical fiber is measured by means of two opto-electronic systems. The systems have optical axes which are perpendicular to each other and to the running axis of the object. Each of the systems further includes a microscope lens for forming a blurred image of the object on a strip of photodetectors. The systems combine their images in an apparatus which calculates an accurate position of each edge of the object by interpolation.
