Abstract:
An optical imaging system with a flexible cable having a first end and a second end. The cable has a central core element including a flexible optical conduit, with a number of wires surrounding the core element to form a tube concentric with an axis defined by the center of the core. The cable has a conductive shield layer surrounding the wires and uniformly spaced apart from the wires An electronic instrument is connected to the first end of the cable and has an illuminator coupled with the optical conduit and a display device connected to the wires. An image transducer is connected to the second end of the cable and is connected to the wires. The wires may be twisted pairs evenly spaced apart from each other, and evenly spaced apart from an axis defined by the core.
