ABSTRACT:
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.degree.. 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. 5 )
