ABSTRACT:
Systems and methods for quickly and accurately measuring the concentricity of a core with respect to a ferrule are provided. A beam splitter arrangement is utilized to separately image both the core and the ferrule outer edge using separate imagers. The two images are combined through coordinate transformation so that the offset of the core with respect to the ferrule center can be determined.
