摘要

在科學技術高速發(fā)展的現(xiàn)代社會中，人類已經(jīng)入瞬息萬變的信息時代，人們在日常生活，生產(chǎn)過程中，主要依靠檢測技術對信息經(jīng)獲取、篩選和傳輸，來實現(xiàn)制動控制，自動調節(jié)，目前我國已將檢測技術列入優(yōu)先發(fā)展的科學技術之一。 由于微電子技術，光電半導體技術，光導纖維技術以及光柵技術的發(fā)展，使得光電傳感器的應用與日俱增。這種傳感器具有結構簡單、非接觸、高可靠性、高精度、可測參數(shù)多、反應快以及結構簡單,形式靈活多樣等優(yōu)點，在自動檢測技術中得到了廣泛應用，它一種是以光電效應為理論基礎，由光電材料構成的器件。它可用于檢測直接引起光量變化的非電量，如光強、光照度、輻射測溫、氣體成分分析等；也可用來檢測能轉換成光量變化的其他非電量，如零件直徑、表面粗糙度、應變、位移、振動、速度、加速度，以及物體的形狀、工作狀態(tài)的識別等。光電式傳感器具有非接觸、響應快、性能可靠等特點，因此在工業(yè)自動化裝置和機器人中獲得廣泛應用。

ABSTRACT
The photoelectric transducer adopts the photoelectric component as the transducer measuring the component. 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.
