自从出现发光二极管LED以来,人们一直在努力追求实现固体光源,随着发光二极管LED制造工艺的不断进步和新型材料(氮化物晶体和荧光粉)的开发及应用,使发白色光的LED半导体固体光源性能不断完善并进入实用阶段。
光纤是20世纪后半叶发展出来的一种新型信息传送材料,光纤最初研究是为了通讯,光纤传感器是伴随着观点技术发展起来的一种新型传感器。光纤传感器随着光纤通信技术的实用化有了迅速发展,且以体积小、重量轻、检测分辨率高、灵敏度高、测温范围宽、保密性好、抗电磁干扰能力强、抗腐蚀性强等明显优于传统传感器的特点广泛应用于工业生产、医疗卫生、国防工程等重要部门。
本文首先概述了白光LED的原理以及合成途径。接着介绍了发光二极管。然后介绍光源与光纤的耦合常采用的两种方法以及耦合效率的影响因素。最后着重光纤传感器,包括其工作原理、分类、优点及发展前景。

Since has appeared light emitter diode LED, the people continuously diligently are pursuing the realization solid photosource, is unceasingly progressive along with the light emitter diode LED manufacture craft and the new material (nitride crystal and luminous powder) the development and the application, causes to turn white the colored light LED semiconductor solid photosource performance unceasingly to consummate and to enter the practical stage .
Optical fiber 20 centuries latter half develops one kind of new information transmission material, the optical fiber at first research is for the communication, the optical fiber sensor is following the viewpoint technological development one kind of new sensor. The optical fiber sensor had the rapid development along with the optical fiber communications ofc technology practical application, also by the volume small, the weight light, the examination resolution high, the sensitivity high, measured the warm scope width, the secrecy good, the anti- electronmagetic interference ability strong, the corrosion resistivity is strong and so on obviously to surpass the traditional sensor the characteristic widely to apply to the industrial production, the medical health, the national defense project and so on the integral part .
This article has first outlined the white light LED principle as well as the synthesis way. Then introduced the light emitter diode. Then the introduction photosource and the optical fiber coupling often uses two methods as well as coupling efficiency influence factors. Finally emphatically optical fiber sensor, including its principle of work, classification, merit and prospects for development .

Since has appeared light emitter diode LED, the people continuously
diligently are pursuing the realization solid photosource, is
unceasingly progressive along with the light emitter diode LED
manufacture craft and the new material (nitride crystal and luminous
powder) the development and the application, causes to turn white the
colored light LED semiconductor solid photosource performance
unceasingly to consummate and to enter the practical stage. The
optical fiber is one kind of new information transmission material
which 20th century latter half develops, the optical fiber at first
research is for the communication, the optical fiber sensor is
following the viewpoint technological development one kind of new
sensor. The optical fiber sensor had the rapid development along with
the optical fiber communications ofc technology practical application,
also by the volume small, the weight light, the examination resolution
high, the sensitivity high, measured the warm scope width, the secrecy
good, the anti- electronmagetic interference ability strong, the
corrosion resistivity is strong and so on obviously to surpass the
traditional sensor the characteristic widely to apply to the
industrial production, the medical health, the national defense
project and so on the integral part. This article has first outlined
the white light LED principle as well as the synthesis way. Then
introduced the light emitter diode. Then the introduction photosource
and the optical fiber coupling often uses two methods as well as
coupling efficiency influence factors. Finally emphatically optical
fiber sensor, including its principle of work, classification, merit
and prospects for development.
