Cov qauv ntawm PIN photodetector

Cov qauv ntawmTus ntsuas duab PIN

Lub tshuab ntes duab, ib lub cuab yeej uas hloov cov teeb liab teeb liab mus rau hauv cov teeb liab hluav taws xob siv cov nyhuv photoelectric, zoo li lub qhov muag tib neeg thiab tuaj yeem ntes tau ob qho tib si pom thiab tsis pom cov teeb liab tsis muaj zog. Vim nws txoj haujlwm ua haujlwm ntawm lub teeb irradiation ua rau muaj kev hloov pauv hauv cov khoom siv lub cev ntawm cov khoom, photodetectors muaj ntau yam khoom siv xaiv thiab ntau hom, txhua tus nrog nws cov xwm txheej siv tshwj xeeb.
Cov hom photodetectors raug faib ua pawg raws li lawv cov yam ntxwv ntawm cov qauv, suav nrog cov khoom siv optoelectronic nqus tsev, cov khoom siv photoconductive detectors,Cov duab PIN, cov phototransistors, thiab cov avalanche diode detectors (APD photodetector). Qhov tshwj xeeb tshaj yog PIN photodetector, uas ua rau thaj chaw depletion dav dua los ntawm kev qhia cov txheej semiconductor hom I uas muaj qhov concentration qis rau hauv PN junction, yog li txo qhov cuam tshuam ntawm kev txav mus los thiab txhim kho qhov ceev teb.
PIN photodiodes tau siv dav hauv ntau qhov chaw xws li kev sib txuas lus pom, kev ntsuas pom, kev kho mob duab, thiab laser ntau vim lawv cov quantum efficiency siab, suab nrov qis, teb dav spectral, thiab teb sai. Piv txwv li, LBTEK's silicon-based amplification detectors thiab balanced photodetectors koom nrog pawg no. Txawm li cas los xij, nws tsim nyog sau cia tias PIN photodetectors muaj kev txwv hauv lawv lub peev xwm los ntes cov teeb liab tsis muaj zog vim tsis muaj qhov nce ntxiv. Lub avalanche photodiode (APD photodetector) ua kom lub photocurrent loj dua los ntawm kev qhia thaj chaw nce tam sim no hauv PIN photodiode thiab siv nws cov nyhuv avalanche multiplication sab hauv. Qhov no muab APD photodetectors kom zoo dua PIN photodetectors hauv kev ntes cov teeb liab tsis muaj zog, nrog rau qhov nce sab hauv txog li 10 txog 100 zaug. Lub hauv paus ntsiab lus ua haujlwm ntawm lub photodetector sib txawv nyob ntawm nws hom tshwj xeeb, tab sis nws cov hauv paus ntsiab lus photoelectric effect siv tau rau ntau hom photodetectors.
Raws li lub hauv paus tseem ceeb ntawm cov tshuab optoelectronic niaj hnub no, kev ua tau zoo ntawm cov photodetectors ncaj qha txiav txim siab qhov tseeb, kev ntseeg siab, thiab kev ruaj khov ntawm tag nrho lub cev. Nws yog siv dav hauv cov teb xws li kev sib txuas lus fiber optic, kev saib xyuas ib puag ncig, kev kho mob duab, kev soj ntsuam tub rog, kev lag luam automation, thiab kev tshawb fawb, lub luag haujlwm rau kev hloov cov teeb liab optical mus rau hauv cov teeb liab hluav taws xob ntsuas tau. Yog li ntawd, kev tshawb pom kom meej thiab raug ntawm cov photodetectors yog qhov tseem ceeb.
