Abstract
This disclosure concerns a cleaning and inspection system for fiber optics that is rapid, reliable and useful for various types of fiber optics. In an embodiment, the system includes a wide field of view (FOV) camera to image the ferrule and rapidly locate the fiber ends and a narrow FOV camera to provide detailed inspection of fiber ends. A cleaning module with a cleaning tip and a cleaning media that is drawn through the tip is used to clean the fiber ends. Images captured by the dual cameras are automatically enhanced and analyzed to determine the effectiveness of the cleaning process and to identify the types and quantity of defects present. In another embodiment, a single higher resolution camera is provided with a lens that can image an entire fiber array and yet enable defects to be detected by analysis of sub-images of each fiber in the fiber array.
