選型參(can)數:

光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)(dian)(dian)傳感(gan)器是將(jiang)光(guang)(guang)(guang)(guang)信號(hao)轉換為電(dian)(dian)(dian)(dian)(dian)信號(hao)的(de)一種(zhong)器件。其工作原(yuan)理基于光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)(dian)(dian)效應(ying)。光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)(dian)(dian)效應(ying)是指光(guang)(guang)(guang)(guang)照射在某些物質(zhi)(zhi)上時(shi)，物質(zhi)(zhi)的(de)電(dian)(dian)(dian)(dian)(dian)子(zi)吸收光(guang)(guang)(guang)(guang)子(zi)的(de)能量而發生(sheng)了(le)相應(ying)的(de)電(dian)(dian)(dian)(dian)(dian)效應(ying)現象。根據光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)(dian)(dian)效應(ying)現象的(de)不同將(jiang)光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)(dian)(dian)效應(ying)分(fen)為三類：外光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)(dian)(dian)效應(ying)、內光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)(dian)(dian)效應(ying)及光(guang)(guang)(guang)(guang)生(sheng)伏應(ying)。光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)(dian)(dian)器件有光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)(dian)(dian)管、光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)(dian)(dian)倍增管、光(guang)(guang)(guang)(guang)敏電(dian)(dian)(dian)(dian)(dian)阻、光(guang)(guang)(guang)(guang)敏二極管、光(guang)(guang)(guang)(guang)敏三極管、光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)(dian)(dian)池等。分(fen)析了(le)光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)(dian)(dian)器件的(de)性能、特性曲線。
