【正文】 選用子午線進行了參數(shù)計算，子午線就是光線的傳播路徑始終經(jīng)過光纖軸并在同一平面內(nèi)，這些參數(shù)計算包括最大入射角或發(fā)射光角度、數(shù)值孔徑、子午線在階躍型光纖中的幾何行程及反射次數(shù)；側(cè)面發(fā)光POF和熒光POF也是按全反射原理進行傳光的，對于單芯側(cè)面發(fā)光POF多是由非固有損耗導致側(cè)面發(fā)光，而對于多芯側(cè)面發(fā)光POF則是由彎曲損耗產(chǎn)生側(cè)面發(fā)光的。熒光POF經(jīng)過特定波長光激發(fā)后發(fā)出特定波長的光，而且激發(fā)光不僅可從端面入射，而且可從側(cè)面入射。Principles of Plastic Optical Fiber CommunicationOptical Communication1. Preface Fiber itself is not light, but can return optical fiber for illumination。 fiber optic lighting, the choice of optical fiber, optical fiber materials according to different, often can be divided into quartz fiber, multiponent glass fiber and plastic optical fiber POF, etc. This paper introduces POF principle of the transmission of light, the other optical fiber transmission principles with the transmission of light POF principle is the same. Perceives light in a transparent cylinder in the forward propagation through multiple total reflection phenomenon, they are the ancient glassblowing artists. The first described the phenomenon of science, but it is the Royal Society, John ? Tyndall demonstrated to the British Royal Society, a famous experiment, he was filled with a water vessel, so that water from the vessel39。s side of the hole out, when the light is projected on the water with the water transfer out. In 1880, William ? Wheeler that light pipe scenario, and the . patent, which is the earliest documented remote lighting device, whose basic principle is: the inner wall coated with a reflective layer center of the tube to the same light source as tap water lead to a number of locations the need for lighting, which is actually the prototype of fiber used for lighting, fiber optic lighting systems can be seen as a simple and above pipeline system similar to a system, in this system, the transmission medium is light, and to transmit light of the pipeline is the optical fiber, optical fiber can transmit light from the light source to the need for lighting a specific area. 1954, Nature magazine published a Hopkin39。s and Kapany successfully with 10,000 to 20,000 of the fiber bundle to transmit images of the article, Van Heel low refractive index cladding that the role of image transmission fiber and the fiber to achieve success layer optical fiber made marked progress in these two subjects as the birth of a new, 1966, the British Standards Institute British Tele Chi
