Abstract

A fixture for optically aligning an optical fiber 11 of, for example, a shielded fiber optic cable 12 with a source 13 provides three translational and two rotational degrees of freedom for precisely adjusting the position and angular orientation of the fiber 11 relative to the source 13.

A fixture for optically aligning an optical fiber 11 of, for example, a shielded fiber optic cable 12 with a source 13 provides three translational and two rotational degrees of freedom for precisely adjusting the position and angular orientation of the fiber 11 relative to the source 13.

As shown, the fixture comprises a clamp 14 and a support plate 15 which are mounted in spaced apart relationship on a base plate 16. The cable 12 is loosely gripped in the clamp 14, and the free end of the optical fiber 11 is threaded through an aperture 17 in the support plate 15. The source 13 is, in turn, mounted on the support plate 15 in alignment with and only a short distance from the aperture 17.

After the tip of the optical fiber 11 is manually brought into course alignment with the source 13, further alignment adjustments are made under the control of an alignment adjustment arm 18. The arm releasably grips the fiber 11 and is mounted on a carriage (not shown) which allows the arm 18 to precisely adjust (1) the position of the fiber 11 along any one or more of three orthogonal axes and (2) the angular orientation of the fiber 11 about either or both of the orthogonal axes which extend radially of the fiber 11.
