P+F傳感(gan)(gan)器(qi)是采用光(guang)(guang)(guang)電(dian)(dian)元(yuan)件作(zuo)為檢測(ce)(ce)元(yuan)件的(de)(de)(de)傳感(gan)(gan)器(qi)。它首先把被測(ce)(ce)量的(de)(de)(de)變化轉換(huan)成光(guang)(guang)(guang)信號的(de)(de)(de)變化，然后(hou)借助(zhu)光(guang)(guang)(guang)電(dian)(dian)元(yuan)件進一步將光(guang)(guang)(guang)信號轉換(huan)成電(dian)(dian)信號。光(guang)(guang)(guang)電(dian)(dian)傳感(gan)(gan)器(qi)一般由(you)光(guang)(guang)(guang)源、光(guang)(guang)(guang)學(xue)通路和光(guang)(guang)(guang)電(dian)(dian)元(yuan)件三部分組成。由(you)光(guang)(guang)(guang)通量對光(guang)(guang)(guang)電(dian)(dian)元(yuan)件的(de)(de)(de)作(zuo)用原理不同所制(zhi)成的(de)(de)(de)光(guang)(guang)(guang)學(xue)測(ce)(ce)控系(xi)統(tong)是多種(zhong)多樣的(de)(de)(de),按(an)光(guang)(guang)(guang)電(dian)(dian)元(yuan)件(光(guang)(guang)(guang)學(xue)測(ce)(ce)控系(xi)統(tong))輸出量性質可分二類,即模擬式光(guang)(guang)(guang)電(dian)(dian)傳感(gan)(gan)器(qi)和脈沖(開關)式光(guang)(guang)(guang)電(dian)(dian)傳感(gan)(gan)器(qi).

模擬(ni)式(shi)光(guang)(guang)電(dian)傳感器是(shi)將被測(ce)量轉換(huan)光(guang)(guang)電(dian)傳感器成連續變化的光(guang)(guang)電(dian)流,它與被測(ce)量間呈單值(zhi)關(guan)系.模擬(ni)式(shi)光(guang)(guang)電(dian)傳感器按被測(ce)量(檢測(ce)目標物(wu)體(ti))方法可分(fen)為透(tou)射(吸(xi)收)式(shi),漫反射式(shi),遮光(guang)(guang)式(shi)(光(guang)(guang)束阻檔)三(san)大類.所(suo)謂(wei)透(tou)射式(shi)是(shi)指被測(ce)物(wu)體(ti)放在光(guang)(guang)路(lu)中(zhong),恒光(guang)(guang)源發出的光(guang)(guang)能量穿過被測(ce)物(wu),部份被吸(xi)收后,

透射(she)光(guang)(guang)(guang)(guang)投射(she)到(dao)光(guang)(guang)(guang)(guang)電(dian)元件(jian)上(shang)(shang);所謂漫反射(she)式(shi)(shi)是(shi)指恒光(guang)(guang)(guang)(guang)源發出的光(guang)(guang)(guang)(guang)投射(she)到(dao)被測物上(shang)(shang),再從被測物體表面反射(she)后(hou)投射(she)到(dao)光(guang)(guang)(guang)(guang)電(dian)元件(jian)上(shang)(shang);所謂遮光(guang)(guang)(guang)(guang)式(shi)(shi)是(shi)指當光(guang)(guang)(guang)(guang)源發出的光(guang)(guang)(guang)(guang)通量經被測物光(guang)(guang)(guang)(guang)遮其(qi)中一部份,使投射(she)剄光(guang)(guang)(guang)(guang)電(dian)元件(jian)上(shang)(shang)的光(guang)(guang)(guang)(guang)通量改變,改變的程度與(yu)被測物體在光(guang)(guang)(guang)(guang)路位置有關.光(guang)(guang)(guang)(guang)敏二(er)極管是(shi)常見的光(guang)(guang)(guang)(guang)傳感器。
