P+F傳(chuan)感器(qi)是采用光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)元(yuan)件(jian)作為檢測(ce)(ce)元(yuan)件(jian)的(de)傳(chuan)感器(qi)。它首先把被測(ce)(ce)量的(de)變化轉換成(cheng)光(guang)(guang)(guang)(guang)信(xin)號的(de)變化，然后借助(zhu)光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)元(yuan)件(jian)進一步將(jiang)光(guang)(guang)(guang)(guang)信(xin)號轉換成(cheng)電(dian)(dian)(dian)信(xin)號。光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)傳(chuan)感器(qi)一般由光(guang)(guang)(guang)(guang)源、光(guang)(guang)(guang)(guang)學(xue)通路和(he)光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)元(yuan)件(jian)三部分組(zu)成(cheng)。由光(guang)(guang)(guang)(guang)通量對光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)元(yuan)件(jian)的(de)作用原(yuan)理不同所(suo)制成(cheng)的(de)光(guang)(guang)(guang)(guang)學(xue)測(ce)(ce)控系(xi)統(tong)是多種多樣的(de),按光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)元(yuan)件(jian)(光(guang)(guang)(guang)(guang)學(xue)測(ce)(ce)控系(xi)統(tong))輸出量性質可(ke)分二類,即(ji)模擬式(shi)光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)傳(chuan)感器(qi)和(he)脈沖(開(kai)關)式(shi)光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)傳(chuan)感器(qi).

模擬式(shi)光電(dian)傳感(gan)器(qi)是將被測(ce)(ce)量轉換光電(dian)傳感(gan)器(qi)成連續變化的(de)(de)光電(dian)流,它與(yu)被測(ce)(ce)量間呈單值(zhi)關系.模擬式(shi)光電(dian)傳感(gan)器(qi)按被測(ce)(ce)量(檢測(ce)(ce)目(mu)標物體)方法可分為(wei)透(tou)射(吸收(shou))式(shi),漫反(fan)射式(shi),遮光式(shi)(光束阻(zu)檔)三大類.所謂透(tou)射式(shi)是指被測(ce)(ce)物體放(fang)在光路中(zhong),恒光源發出的(de)(de)光能(neng)量穿過被測(ce)(ce)物,部份(fen)被吸收(shou)后,

透射(she)(she)(she)光(guang)投(tou)射(she)(she)(she)到光(guang)電元件(jian)(jian)上(shang);所謂漫反(fan)射(she)(she)(she)式(shi)是指恒光(guang)源發出(chu)的光(guang)投(tou)射(she)(she)(she)到被(bei)測(ce)物上(shang),再從被(bei)測(ce)物體表面反(fan)射(she)(she)(she)后(hou)投(tou)射(she)(she)(she)到光(guang)電元件(jian)(jian)上(shang);所謂遮光(guang)式(shi)是指當(dang)光(guang)源發出(chu)的光(guang)通量經(jing)被(bei)測(ce)物光(guang)遮其中一部份(fen),使投(tou)射(she)(she)(she)剄光(guang)電元件(jian)(jian)上(shang)的光(guang)通量改變,改變的程度(du)與(yu)被(bei)測(ce)物體在光(guang)路位(wei)置有關.光(guang)敏二極管是常見的光(guang)傳感器。
