Abstract

A system for measuring a combination of optical transmission properties of fiber optic waveguides. A polarized light pulse probe is injected into one end of the optical fiber. Reflections from discontinuities within the fiber are unpolarized whereas reflections of the probe pulse incident to its injection remain polarized. The polarized reflections are prevented from reaching a light detector whereas reflections from the discontinuities reaches the detector.

System for testing optical fibers

Patent Davies, Terence J [Santa Barbara, CA]; Franks, Larry A [Santa Barbara, CA]; Nelson, Melvin A [Santa Barbara, CA]

A system for nondestructively determining the attenuation coefficient, .alpha.(.lambda.), of low-loss optical fiber wave guides. Cerenkov light pulses are generated at a plurality of locations in the fiber by a beam of charged particles. The transit times of selected spectral components and their intensities are utilized to unfold the .alpha.(.lambda.) values over the measured spectrum.

Fiber optic detector for immuno-testing

Patent Partin, Judy K [Idaho Falls, ID]; Ward, Thomas E [Idaho Falls, ID]; Grey, Alan E [Idaho Falls, ID]

A portable fiber optic detector that senses the presence of specific target chemicals in air or a gas by exchanging the target chemical for a fluoroescently-tagged antigen that is bound to an antibody which is in turn attached to an optical fiber. Replacing the fluorescently-tagged antigen reduces the fluorescence so that a photon sensing detector records the reduced light level and activates an appropriate alarm or indicator.

Optical fiducial timing system for X-ray streak cameras with aluminum coated optical fiber ends

Patent Nilson, David G [Oakland, CA]; Campbell, E Michael [Pleasanton, CA]; MacGowan, Brian J [Livermore, CA]; ...

An optical fiducial timing system is provided for use with interdependent groups of X-ray streak cameras (18). The aluminum coated (80) ends of optical fibers (78) are positioned with the photocathodes (20, 60, 70) of the X-ray streak cameras (18). The other ends of the optical fibers (78) are placed together in a bundled array (90). A fiducial optical signal (96), that is comprised of 2.omega. or 1.omega. laser light, after introduction to the bundled array (90), travels to the aluminum coated (82) optical fiber ends and ejects quantities of electrons (84) that are recorded on the data recording mediamore » « less
