    摘要: A method is provided for assembling an arthroscopic probe which includes bending a linear image-transmitting optical fiber about a heated pivot point so that the distal end of the fiber is oblique to the proximal end. A lens is then attached to the distal face of the image-transmitting optical fiber by means of an adhesive and the resulting image path is positioned in a hollow needle with the lens exposed at the distal end and the optical fiber exposed at the proximal end. An illuminating optical fiber is also positioned in the needle adjacent the image path and the two are anchored therein by a curable filler material. Finally, the needle is proximally mounted in a base such that the proximal faces of the image-transmitting and illuminating optical fibers are exposed.

    摘要: A security screen assembly comprises a screen of mesh material with an optical path formed from at least one optical fiber integrally interwoven with the screen material in a generally serpentine path. A light source or transmitter is coupled to the first end of the optical path while a suitable light detector is coupled to detect light emitted from the second end of the optical path. An interface unit connects the screen to a remote alarm control unit for activating an alarm if the detected light signal falls below a predetermined intensity.
