  • Patent number: 4955687
    Abstract: A fiber optic telescope for use as an electromagnetic energy collector, wherein two or more collector cells are connected via the fiber optic waveguide and a converging connecting means. A plurality of the cells may be connected in series or in a cascading relationship. Applications of the system include a telescope, a solar energy collector or any other uses where collection of electromagnetic radiation is required.

  • Patent number: 4828348
    Abstract: Disclosed is a fiber optic telescope composed of at least one fiber optic telescopic cell. The fiber optic cell is composed of a refracted light conveyor and a reflected light retriever. The refracted light conveyor is comprised of a lens, a cone, a dual diametered fiber optic cable, a fiber optic connector, a last fiber optic cable, and an eyepiece or other suitable light receiving apparatus. The reflected light retriever is comprised of six fiber optic cables, two fiber optic connectors, and two secondary fiber optic cables. The refracted light conveyor and the reflected light retriever are held together by a holder, an adjuster, and a washer. The fiber optic telescope overcomes problems associated with the propagation of light in a telescope: reflection, refraction, image formulation and magnification. Additionally the fiber optic telescope is capable of propagating solar light with an efficiency of 95%.

  • Patent number: 4824204
    Abstract: Disclosed is a fiber optic connector capable of joining at least one fiber optic cable to a dual diametered fiber optic cable, in which light loss caused by axial offset is eliminated and light loss caused by either angularity offset or gaps between the fiber end faces is reduced. Also disclosed in a multiposition clamp capable of juxtaposing a plurality of fiber optic connectors.
