It changes the change measured into a change of the optical signal at first, then further change the optical signal into an electric signal through the photoelectric component. The photoelectric transducer is generally made up of light source, optical thorough fare and photoelectric component three parts. The photoelectric detection method has precision high, reacts fast, advantage of exposed to ing etc.s, and can examine the parameter more,the transducer is of simple structure, the form is flexible, so, it is very extensive that the photoelectricity type transducer is employed in measuring and controlling. The photoelectric transducer realizes the key component that the photoelectricity changes in various photoelectric detection systems, it change into electric device of signal optical signal (infrared can seeing and purple other ray radiation). The photoelectricity type transducer is regarded photoelectric device as and changed the transducer of the component. It was not electric consumption that it caused the light quantity to change directly that it can be used for measuring, only strong, illuminance, radiation examine warmly, the gas composition is analyzed etc.; Other ones that can also be used and measured and can change into a light quantity and change are not the electric consumption such as part diameter, surface roughness, meets an emergency, the displacement, vibration, pace, acceleration, and the form of object, discernment of working state,etc.. The photoelectricity type transducer is not exposed to, respond the fast, reliable characteristic of performance, so won extensive application in the industrial automation device and machine philtrum. In recent years, new Devices photoelectric constantly emerge, especially CCD picture the births of transducer, transducers photoelectric the further to last chapter innovated to turn on.Keywords:Photoelectric component Transducer classification Application of transducer目录第一章绪论 (1)1.1 传感器发展史 (1)1.2光电传感概述 (2)第二章光电传感器基本原理 (3)2.1 光电效应 (3)2.2 光电元件及特性 (3)2.3 光电传感器 (6)第三章 CCD传感器 (11)3.1 光固态图象传感器 (11)3.1.1 CCD的结构和基本原理 (11)3.1.2 线型CCD图像传感器 (12)3.1.3 面型CCD图像传感器 (13)3.2 C CD图像传感器应用 (15)3.2.1 工件尺寸检测 (15)3.2.2 CCD传感器在公共交通上的应用 (16) 第四章光纤传感器 (17)4.1 光纤传感器的原理和组成 (17)4.2 光纤传感器的类型及特点 (17)4.3 光纤传感器的应用领域 (18)4.4 光纤传感器(FOS)应用原理 (20) 4.5 光纤传感器的实际应用 (21) 4.5.1 光纤液位传感器 (22)4.5.2 电力工业中的应用 (22)第五章其它光电传感器 (25)5.1 高速光电二极管 (25)5.1.1 PIN结光电二极管 (25)5.1.2 雪崩光电二极管(APD) (26) 5.2 色敏光电传感器 (26)5.3 光位置传感器 (27)第六章总结与展望 (29)6.1 总结 (29)6.2 展望 (30)致谢 (31)参考文献 (33)第一章绪论 1第一章绪论1.1 传感器发展史传感技术的发展经历了三个阶段,即结构型传感器、物性型传感器和智能型传感器,其测量技术、方法和特点的发展历程见表1。
