ABSTRACT:
A device for use in detecting, characterizing and correcting flaws in optic fibers includes a light source for generating a beam of light at an optic fiber, a detector measurer for detectably measuring at least one of refracted light rays, diffracted light rays and scattered light rays from the beam and generating a signal in response thereto, a computer-based device operatively associated with the detector measurer for receiving the signal and manipulating the signal to produce an output indicating one of a normal area and a flawed area, a camera device operatively associated with the computer-based device and responsive to the output for visually recording the flawed area in response to indication of a flawed area and permitting display of thereof. Also, a method provided includes the steps of directing a beam of light at an optic fiber, detectably measuring at least one of refracted light rays, diffracted light rays and scattered light rays from the beam and generating a signal in response thereto, employing a computer-based device for receiving the signal and manipulating the signal to produce an output indicative of one of a normal area and flawed area, and employing a camera for recording the flawed area in response to indication of the flawed fiber. The method further includes the steps of displaying the flawed area and removing the flawed area from the fiber.
