Method of and apparatus for measuring the geometric characteristics of nominally cylindrical guiding structures

摘要

The method and the device are intended to measure the geometrical characteristics of components of optical communication systems comprising a body (1) with nominally cylindrical external surface and an internal element (2) nominally coaxial with body (1). The component is placed in a V-groove (3) and rotated by 360 DEG . A TV-camera (8) detects the curve (4) described by a point of the internal element during the rotation. Numerical analysis of the curve provides, by a single operation, eccentricity of the internal element and non-circularity of the external surface of the body. (FIG.
