纤维光学是一门新兴的学科,是近代光学领域中的一个重要分支,它是研究在透明的光学纠维中光线和图象传输的科学。光学纤维通常是一种带套层的圆柱形透明细丝,可由玻璃、石英、塑料等材料在高温下拉制而成。光学纤维的出现,给人们提供了一种类似于电缆线一样的柔软的光导管,而光束和图象就沿着这种弯曲的导管从一端传送到另一端。 利用这种细长纤维导管来传送光线和图象,实际上并不是新的概念。早先,希腊的吹玻璃工人在工作中就看到光线在弯道中透过的现象,并且他们还利用这种现象制作成装饰用的各种玻璃器具。在1854年,英国丁达尔(J.Tydall)在皇家学会的一次讲演中说,光线能够沿着盛水的弯管道进行全反射而传播。以后,他又用实验观察并证实了这个现象。实验
Fiber optics is an emerging discipline and is an important branch of modern optics. It is a science that studies the transmission of light and image in transparent optical correction. Optical fiber is usually a kind of cylindrical transparent filament with a sleeve, made of glass, quartz, plastic and other materials at high temperature. The advent of optical fibers gives people a soft, light-like conduit similar to a cable, along which beams and images travel from one end to the other. The use of such slender fiber catheters to transmit light and images is not in fact a new concept. Earlier, Greek glassblowers saw the transmission of light through corners during work, and they also made use of this phenomenon to make decorative glassware. In 1854, J.Tydall of the United Kingdom said in a lecture by the Royal Society that light could be transmitted by total reflection along curved pipes of water. Later, he observed the experiment and confirmed this phenomenon. experiment
