Abstract: Systems and methods of measuring ferrule-core concentricity for an optical fiber held by a ferrule are disclosed. The method includes: generating ferrule distance data by measuring distances to a ferrule outside surface as a function of rotation angle using a distance sensor and rotating either the ferrule or the distance sensor about an axis of rotation that is off-center from the true ferrule axis; aligning the axis of rotation with the fiber core; using the ferrule distance data to determine a position of the true ferrule center relative to the optical fiber core; and measuring the concentricity as the distance between the true center of the ferrule and the optical fiber core.
