選型參(can)數:

光(guang)(guang)電(dian)(dian)(dian)(dian)傳感器(qi)(qi)是將光(guang)(guang)信(xin)號(hao)轉換(huan)為電(dian)(dian)(dian)(dian)信(xin)號(hao)的一種器(qi)(qi)件。其工作原理基于(yu)光(guang)(guang)電(dian)(dian)(dian)(dian)效(xiao)應(ying)。光(guang)(guang)電(dian)(dian)(dian)(dian)效(xiao)應(ying)是指光(guang)(guang)照射在(zai)某些(xie)物質上時，物質的電(dian)(dian)(dian)(dian)子吸收光(guang)(guang)子的能量而發生(sheng)了相(xiang)應(ying)的電(dian)(dian)(dian)(dian)效(xiao)應(ying)現象。根據光(guang)(guang)電(dian)(dian)(dian)(dian)效(xiao)應(ying)現象的不(bu)同將光(guang)(guang)電(dian)(dian)(dian)(dian)效(xiao)應(ying)分(fen)為三類：外光(guang)(guang)電(dian)(dian)(dian)(dian)效(xiao)應(ying)、內(nei)光(guang)(guang)電(dian)(dian)(dian)(dian)效(xiao)應(ying)及光(guang)(guang)生(sheng)伏應(ying)。光(guang)(guang)電(dian)(dian)(dian)(dian)器(qi)(qi)件有光(guang)(guang)電(dian)(dian)(dian)(dian)管(guan)、光(guang)(guang)電(dian)(dian)(dian)(dian)倍增(zeng)管(guan)、光(guang)(guang)敏(min)電(dian)(dian)(dian)(dian)阻、光(guang)(guang)敏(min)二極(ji)管(guan)、光(guang)(guang)敏(min)三極(ji)管(guan)、光(guang)(guang)電(dian)(dian)(dian)(dian)池等。分(fen)析了光(guang)(guang)電(dian)(dian)(dian)(dian)器(qi)(qi)件的性(xing)能、特(te)性(xing)曲線。
