A novel intensity modulated fiber optic displacement sensor based on the relative motion of an optical fiber and a graded index lens is described. So while yes, current fiber optics transmit data as fast as light is able to pass through them, theyre far off from the actual speed of light as we commonly think of it. The reason the new fibers come so much closer to the true speed of light is that they are hollow. This fiber-optic sensor measures displacement with a 10 /spl mu/m resolution and covers 20 mm range.
