Fiber optic cable transmits picture from slide to video monitor.

Fiber optic cable transmits picture from slide to video monitor. A fiber optic cable, composed of many thin fibers, is able to transmit an image. In this demo, one end of the cable is held against a portion of a well-lit color slide. The other end of the cable is sent through a x4 microscope objective into a video camera, which then sends the image to a video monitor for the class to see. (Note: There is a gap of about .5 inches between the end of the fiber optic and the microscope objective). How is such a fiber optic cable created? It's easy: a coil consisting of a single long fiber optic strand is held tightly at one spot and then is severed at that section. Both separate ends are then carefully bound so that the fibers do not move. An image presented at one end appears at the other end via total internal reflection.
