ScienceDaily is reporting that a new form of endoscope developed at the University of Washington is more like swallowing a pill than the typical "massive" cable. The pill, complete with a 1.4 mm wide tether, contains a single optical fiber for illumination and six fibers for collecting light. "Once swallowed, an electric current flowing through the UW endoscope causes the fiber to bounce back and forth so that its lone electronic eye sees the whole scene, one pixel at a time. At the same time the fiber spins and its tip projects red, green and blue laser light. The image processing then combines all this information to create a two-dimensional color picture."
