Enhanced Image of Tissue Fibers

Caption: These fibers from rabbit muscle appear extraordinarily distinct through the standing wave fluorescence microscope developed at Carnegie Mellon University. The fibers are pressed between two parallel glass plates, separated by the yellow microbeads that are 1/5,000th of a millimeter in diameter. All the fibers would appear in focus using a conventional microscope, but the standing wave fluorescence microscope can focus on fibers at different levels even within this very thin interval.
