FIBER OPTICS
A method of directing light down a very thin glass fiber. Fiber Optics are
used mostly in communication, but find theater applications in star cloths
which are black backcloths with the ends of optical fibers poked through, to
create a mass of pin pricks of light. A large bundle or harness of fibers
may be fed from one light source, sometimes with a motorized color or
flicker wheel. New technology enables digital sound signals to be sent down
optical fibers, replacing heavy and expensive multicore cables.
