Abstract
An apparatus and method of ascertaining the position of a core within a fiberoptic cable and calculating the position of the core relative to the cladding and jacket of the fiberoptic cable. The apparatus provides for observing of the end of the fiberoptic cable by using grazing incident illumination which causes the diameter of the core, the diameter of the cladding and the diameter of the jacket of the fiberoptic cable to be readily observed and then utilizing of a microscope and associated software to read the average diameter of the core and its position relative to the average diameter of the cladding and the average diameter of the jacket which will then make a determination as to how far off center the core is relative to the cladding and the jacket.
