邦納Banner光電傳感器是采用光電元件作為檢測元件的傳感器。它首先把被測量的變化轉(zhuǎn)換成光信號的變化，然后借助光電元件進(jìn)一步將光信號轉(zhuǎn)換成電信號。光電傳感器一般由光源、光學(xué)通路和光電元件三部分組成。
光電傳感器一般由光源、光學(xué)通路和光電元件3 部分組成。其基本原理是以光電效應(yīng)為基礎(chǔ)，把被測量的變化轉(zhuǎn)換成光信號的變化，然后借助光電元件進(jìn)一步將光信號轉(zhuǎn)換成電信號。光電效應(yīng)是指用光照射某一物體，可以看作是一連串帶有一定能量為的光子轟擊在這個(gè)物體上，此時(shí)光子能量就傳遞給電子，并且是一個(gè)光子的全部能量一次性地被一個(gè)電子所吸收，電子得到光子傳遞的能量后其狀態(tài)就會(huì)發(fā)生變化，從而使受光照射的物體產(chǎn)生相應(yīng)的電效應(yīng)。通常把光電效應(yīng)分為3 類：（1 ）在光線作用下能使電子逸出物體表面的現(xiàn)象稱為外光電效應(yīng)，如光電管、光電倍增管等；（2 ）在光線作用下能使物體的電阻率改變的現(xiàn)象稱為內(nèi)光電效應(yīng)，如光敏電阻、光敏晶體管等；（3 ）在光線作用下，物體產(chǎn)生一定方向電動(dòng)勢的現(xiàn)象稱為光生伏*應(yīng)，如光電池等。
邦納Banner光電傳感器由光通量對光電元件的作用原理不同所制成的光學(xué)測控系統(tǒng)是多種多樣的,按光電元件(光學(xué)測控系統(tǒng))輸出量性質(zhì)可分二類,即模擬式光電傳感器和脈沖(開關(guān))式光電傳感器.模擬式光電傳感器是將被測量轉(zhuǎn)換成連續(xù)變化的光電流,它與被測量間呈單值關(guān)系.模擬式光電傳感器按被測量(檢測目標(biāo)物體)方法可分為透射(吸收)式,漫反射式,遮光式(光束阻檔)三大類.所謂透射式是指被測物體放在光路中,恒光源發(fā)出的光能量穿過被測物,部份被吸收后,透射光投射到光電元件上;所謂漫反射式是指恒光源發(fā)出的光投射到被測物上,再從被測物體表面反射后投射到光電元件上;所謂遮光式是指當(dāng)光源發(fā)出的光通量經(jīng)被測物光遮其中一部份,使投射到光電元件上的光通量改變,改變的程度與被測物體在光路位置有關(guān).
工作原理
光電傳感器是通過把光強(qiáng)度的變化轉(zhuǎn)換成電信號的變化來實(shí)現(xiàn)控制的。
光電傳感器在一般情況下，有三部分構(gòu)成，它們分為：發(fā)送器、接收器和檢測電路。
發(fā)送器對準(zhǔn)目標(biāo)發(fā)射光束，發(fā)射的光束一般來源于半導(dǎo)體光源，發(fā)光二極管(LED)、激光二極管及紅外發(fā)射二極管。光束不間斷地發(fā)射，或者改變脈沖寬度。接收器有光電二極管、光電三極管、光電池組成。在接收器的前面，裝有光學(xué)元件如透鏡和光圈等。在其后面是檢測電路，它能濾出有效信號和應(yīng)用該信號。
此外，光電開關(guān)的結(jié)構(gòu)元件中還有發(fā)射板和光導(dǎo)纖維。
應(yīng)用
用光電元件作敏感元件的光電傳感器，其種類繁多，用途廣泛。按光電傳感器的輸出量性質(zhì)可分為兩類：（1 ）把被測量轉(zhuǎn)換成連續(xù)變化的光電流而制成的光電測量儀器，可用來測量光的強(qiáng)度以及物體的溫度、透光能力、位移及表面狀態(tài)等物理量。例如：測量光強(qiáng)的照度計(jì)，光電高溫計(jì)，光電比色計(jì)和濁度計(jì)，預(yù)防火災(zāi)的光電報(bào)警器，構(gòu)成檢查被加工零件的直徑、長度、橢圓度及表面粗糙度等自動(dòng)檢測裝置和儀器，其敏感元件均用光電元件。半導(dǎo)體光電元件不僅在民用工業(yè)領(lǐng)域中得到廣泛的應(yīng)用，在軍事上更有它重要的地位。例如用硫化鉛光敏電阻可做成紅外夜視儀、紅外線照相儀及紅外線導(dǎo)航系統(tǒng)等；（2 ）把被測量轉(zhuǎn)換成繼續(xù)變化的光電流。利用光電元件在受光照或無光照射時(shí)" 有" 或"無"電信號輸出的特性制成的各種光電自動(dòng)裝置。光電元件用作開關(guān)式光電轉(zhuǎn)換元件。例如電子計(jì)算機(jī)的光電輸入器，開關(guān)式溫度調(diào)節(jié)裝置及轉(zhuǎn)速測量數(shù)字式光電測速儀等。
