Advances in fiber optics techniques are increasing the need for better fiber inspection and submicron measurements of cables, connectors, and other components. As a result, manufacturers are seeking to decrease fiber inspection times from tens of seconds to milliseconds, while eliminating subjective human factors such as different operators and operator fatigue. Integrating machine vision, motion control, and data acquisition enables engineers to make multiple measurements resulting in greater flexibility and productivity. There are 2 areas where automation adds value. One is in the inspection of newly cleaved or manufactured fiber because imperfections can cause severe power attenuation. Typical fiber inspection measurements involve core-cladding diameter and concentricity, and non-circularities. Identification measurements include edge defects, blemishes, dust, and scratches. These measurements can be obtained using optical inspection techniques in tandem with image processing and analysis algorithms.
