Technology Description

Researchers at the University of Iowa have identified a use for coherent fiber bundle technology to achieve the simultaneous transfer of white light and image data in endoscopic applications. This technology involves the etching or abrasion of the outer portions of the proximal end of the bundle (shown in illustration, upper left). This etched site is used as the entry point for the desired light source used to illuminate the endoscope’s target. The light is transmitted through specific channels in the bundle and released out of the distal end of the endoscopic apparatus in a halo fashion. (The ring of light as seen from the endoscopic target’s point of view is shown in illustration.) This style of target illumination produces multi-directional lighting that reduces many of the visual anomalies that can arise from conventional endoscopic lighting technologies. The center portion of the bundle (shown in black in the illustration) collects the image data and transmits it back to the camera for display.
