Abstract:
Heating and drawing bundles of optical fibers under superatmospheric pressure to avoid the formation of gas bubbles therewithin and blemishing caused by their inclusions in components drawn from the bundle. Apparatus is provided within which heating and drawing of the bundle of optical fibers is accomplished in a pressure chamber while the component being drawn therefrom is continuously removed from the chamber through a fluid sealed gland.
Abstract:
METHOD OF MAKING FIBER OPTICAL IMAGE-CONDUCTING DEVICES EACH OF DIFFERENT THICKNESSES IN DIFFERENT PARTS CONSIDERED IN THE LONGITUDINAL DIRECTION THEREOF, AND INCLUDING THIN ELONGATED LIGHT-ABSORBING MEANS DISPERSED AND THE FIBER OPTICAL DEVICE AND EXTENDING LONGITUDINALLY FROM END-TO-END THEROF, SAID METHOD BEING SUCH AS TO FORM ABSORBING MEANS OF SUCH VARYING CONTROLLED STRAY LIGHT CHARACTERISTICS AS TO PROVIDE UNIFORM TRANSMISSION OF OPTICAL ENERGY THROUGH ALL PARTS OF THE IMAGE-CONDUCTING DEVICE FORMED THEREBY.
Abstract:
Fiber optical faceplates adapted to be coupled together in close physical contact to transfer light from one faceplate into the other with increased efficiency.
Abstract:
Improving the light-transmitting efficiency of a clad lightconducting fiber by minimizing core-cladding interfacial defects. Elongated open channels extending longitudinally of the fiber are formed within the cladding to cushion the expansion of gases existing and/or created along the fiber core-cladding interface during fabrication of the fiber.
