  • Method of measuring circularity of an optical fiber
    Patent number: 7110657
    Abstract: Distortion introduced by an imaging system is characterized by positioning a generally cylindrical object and imaging optics in a first relative angular position about an axis of rotation that substantially coincides with the longitudinal axis of the object and employing the imaging optics to image the end face of the object on a detector. First and second definitions of the shape of the image of the periphery of the end face of the object are extracted from image data provided by the detector when the object and the imaging optics are in first and second relative angular positions. The first and second definitions are compared.

  • Apparatus and method for preparing a coated optical fiber
    Patent number: 6904226
    Abstract: A method of preparing a coated optical fiber for coupling to a face of an optical device includes placing the coated fiber so that it extends through a stripping station, a cleaning station and a cleaving station. A stripper at the stripping station is brought into engagement with the fiber and relative motion between the fiber and the stripping station, the cleaning station and the cleaving station is effected lengthwise of the fiber, whereby the coating is stripped from a medial length segment of the fiber as the cleaning device at the cleaning station is activated for cleaning fragments of coating material from the medial length segment of the fiber as the medial length segment passes through the cleaning station and the cleaning device is deactivated and stripping is discontinued.
