| 181 | Improved method of manufacture for clad optical conduit | US769628 | 1991-09-30 | US5149467A | 1992-09-22 | Jamshid J. Zarian |
| A flexible, clad, monofilament optical conduit having a flexible light transmitting polymeric core having a relatively high refractive index which is surrounded by a shrunk, heat shrinkable cladding having a relatively low refractive index in comparison to that of the core and which has a relatively small, uniform gap between the outer periphery of the core and the inner periphery of the heat shrinkable cladding, and a method of manufacture whereby a plurality of such conduits are simultaneously produced by polymerization of the conduit core forming material within a length of unshrunken heat shrinkable material which in turn is contained within a relatively thick, durable protective tubing and removal of the relatively thick protective tubing subsequent to polymerization and then shrinking the heat shrinkable material to form a relatively uniform gap between the core and the clad. In order to prevent its collapse, the heat-shrinkable cladding is pressurized with an inert gas prior to being inserted within the protective tubing. | ||||||
| 182 | Linear optical conduits | US446011 | 1989-12-13 | US5067831A | 1991-11-26 | John A. Robbins; Jamshid J. Zarian; Sandford R. Willford |
| The present invention is directed to a heat shrink clad core optical conduit and to an optical conduit having either a thermoplastic, thermoset or liquid, light transmitting core surrounded by, preferably a fluoropolymer cladding which is in turn surrounded by a tight-fitting, finish polymer jacket which may be either transparent or translucent, and is preferably made of a polyvinyl chloride, polycarbonate, acrylic or silicone material. Numerous fillers and inserts may be used in the finish jacket polymer and the finish jacket polymer may be formed into various shapes. Bondable jacket materials may be used. The preferred method of forming the manufacturing jacket around a heat shrinkable fluoropolymer cladding is by extruding a low extrusion temperature polymer over a heat shrink clad in its expanded form into which an increased interior pressure is maintained to prevent shrinkage during the extrusion process. The preferred method of forming the finish jacket around a base clad core material is by an extrusion process where the finish jacket material is extruded over a heat shrink type fluoropolymer clad, in its expanded form, cured thermoset core thereby simultaneously shrinking the clad. | ||||||
| 183 | Process for the optical scanning of an object and device for the implementation of said process | US408506 | 1989-10-16 | US5030010A | 1991-07-09 | Gebhard Birkle |
| A device for optically scanning an object includes a nozzle which is connected to a source of pressurized liquid. The nozzle generates a liquid stream which can be directed at the object. The device further includes a laser which is arranged to direct a beam of light at the object in order to scan the latter, and a sensor for receiving and analyzing light reflected from the object. The laser and the nozzle are positioned relative to one another in such a manner that light reflected from the object enters the liquid stream which then conducts the reflected light to the nozzle. The nozzle is connected to the sensor by at least one optical fiber which functions to conduct the reflected light from the nozzle to the sensor. One or more additional optical fibers may be provided to conduct light from the laser to the nozzle. The liquid stream then serves not only to conduct reflected light from the object to the nozzle but also to conduct the light used for scanning from the nozzle to the object. | ||||||
| 184 | Liquid filled flexible distal tip light guide | US282932 | 1989-02-27 | US4927231A | 1990-05-22 | Jeffrey I. Levatter |

| 186 | Totally internally reflecting light conduit | US903657 | 1986-09-05 | US4805984A | 1989-02-21 | Sanford Cobb, Jr. |
| A hollow, tubular light conduit including a wall of a transparent polymeric material, and the wall having a structured surface and an opposite, smooth, glossy surface, and at least a portion of the cross-section of the wall lying in a smooth arcuate curve, wherein light striking the inner surface, within an acceptable angular range, is contained by total internal reflection. The structured surface includes a linear array of substantially right angled isosceles prisms arranged side-by-side to form grooves. In addition, the perpendicular sides of the prisms make an angle of approximately 45.degree. with the tangent to the smooth surface. Because of the flexibility of the light conduit and its ability to totally internally reflect light, a manipulated light conduit may be utilized in a variety of ways, for example, as a light fixture whereby some of the light directed into the light conduit is emitted from the light conduit for illumination or for use as a secondary light source. A suitable light source may include artificial or solar energy. However, when the light fixture operates as a warning light it is preferred that a strobe light be used. | ||||||
| 187 | Apparatus for continuously controlled emission of light from prism light guide | US47661 | 1987-05-08 | US4787708A | 1988-11-29 | Lorne A. Whitehead |
| A variety of techniques are used to effect continuously controlled emission of light from a light guide. For example, the light guide may contain a mechanism formed of a substantially non-light absorptive material having a density which varies as a function of the length of the light guide. The mechansim causes light to escape from the light guide at a rate which varies along the length of the light guide, such that the amount of light escaping, per unit length, along the light guide has a selected distribution of values. Alternatively, the light guide's central path may be non-linear. As a further alternative, the average cross-sectional dimension of each of the plane segments aforesaid may be non-constant. As yet another alternative, a first portion of the light guide may comprise prism light guide material and the remaining portion may be such that a substantial portion of light incident thereupon is allowed to escape therethrough. | ||||||
| 188 | Method of manufacturing a light conductor and hollow metal light conductor manufactured according to the method | US905227 | 1986-09-08 | US4763398A | 1988-08-16 | Albert Huizing; Willy J. B. Felder; Antonius W. Tijssen |
| The invention provides a method of manufacturing a hollow metal light conductor in which at least one metal layer is provided on a core of a synthetic resin material, for example, polymethylmethacrylate, after which the core is removed, and a metal tube is formed. The core is preferably removed by slightly elongating the core so that the cross-section is reduced, after which the metal light conductor can be pulled from the core. The reflecting metal layer on the inside surface of the light conductor preferably is of aluminium. The invention provides a hollow metal light conductor, for example, for use in an optical spectrometer, which is also suitable in particular to be used for light having a short wavelength, to less than 200 nm. | ||||||

The dielectric material is acrylic plastic or optically clear glass and the light guide includes an outer jacket for protecting the outer surface. | ||||||

| 196 | X-ray and gamma ray waveguide, cavity and method | US787172 | 1977-04-13 | US4122342A | 1978-10-24 | Victor Vali; Reuben S. Krogstad; H. Robert Willard |
| An X-ray and Gamma ray waveguide, cavity, and method for directing electromagnetic radiation of the X-ray, Gamma ray, and extreme ultraviolet wavelengths. A hollow fiber is used as the waveguide and is manufactured from a material having an index of refraction less than unity for these wavelengths. The internal diameter of the hollow fiber waveguide and the radius of curvature for the waveguide are selectively predetermined in light of the wavelength of the transmitted radiation to minimize losses. The electromagnetic radiation is obtained from any suitable source and upon introduction into the waveguide is transmitted along a curvilinear path. The waveguide may be formed as a closed loop to create a cavity or may be used to direct the electromagnetic radiation to a utilization site. | ||||||
