Abstract
Abstract A fiber optic buffer defect detection system including a laser, for illuminating the fiber buffer with a collimated beam of light energy, and detectors for detecting any scattering of the beam, from a defect in the fiber buffer. The detectors are mounted to collect scattering out of a radial plane defined by the angular rotation of the beam about the fiber at the point of intersection of the beam with the fiber buffer.

Claim 1
Independent Claim
143 words
An optic fiber buffer defect detection system comprising: means for illuminating a first optical fiber with a collimated beam for electromagnetic energy along a transverse axis thereof, said transverse axis being substantially orthogonal to the longitudinal axis of said fiber; means for detecting any scattering of said beam, from a defect in said fiber, out of a radial plane defined by the angular rotation of said beam about said fiber at the point of intersection of said beam with said fiber; and retaining means for retaining and illuminating means and said detecting means relative to said fiber, said retaining means including a dish, mounted in a plane substantially parallel with said transverse axis, having a first aperture at the radial center thereof for receiving said fiber and an iris diaphragm mounted in said first aperture for substantially closing around said first optical fiber.
