Photodiode kev txhim kho Photodiode thev naus laus zis tau ua kom zoo nyob rau hauv xyoo 1950 thiab nyob rau tom kawg ntawm kaum xyoo ntawd tus PIN photodiode tau tsim. Kev nqus lub teeb nyob rau hauv qhov chaw dav dav ntawm tus qauv PIN tau tshawb xyuas thawj zaug hauv ib daim ntawv luam tawm xyoo 1959 los ntawm Gartner.
Leej twg tsim photodiode?
It was invented by Dr. John N. Shive (ntau dua rau nws lub tshuab nthwv dej) ntawm Tswb Labs hauv xyoo 1948 tab sis nws tsis tau tshaj tawm txog xyoo 1950. Cov electrons uas tsim los ntawm photons hauv lub hauv paus-collector junction yog txhaj rau hauv lub hauv paus, thiab lub photodiode tam sim no yog amplified los ntawm transistor qhov nce tam sim no β (los yog hfe).
Thaum twg yog phototransistor tsim?
Hnub no hauv 1950, kev tsim tawm ntawm phototransistor tau tshaj tawm los ntawm Tswb Xov Tooj Laboratories. Qhov no yog transistor ua los ntawm lub teeb es tsis yog hluav taws xob tam sim no, tsim los ntawm Dr. John Northrup Shive.
YPuas yog photodiode thiab photodetector tib yam?
Raws li lub npe qhov txawv ntawm photodiode thiab photodetector
yog tias photodiode yog ib qho khoom siv hluav taws xob ob lub davhlau ya nyob twg uas nws cov yam ntxwv hluav taws xob yog lub teeb-sensitive thaum photodetector yog txhua yam khoom siv. siv los ntes hluav taws xob hluav taws xob.
Yuav ua li cas siv lub photodiode?
Photodiodes yog siv rau hauv kev paub txog tus cwj pwm. Photodiodes yog siv rau qhov ntsuas qhov tseeb ntawm kev siv lub teeb hauv kev tshawb fawb thiab kev lag luamPhotodiodes sai dua thiab nyuaj dua li ib txwm PN hlws ris diode thiab yog li nquag siv rau kev tswj teeb pom kev zoo thiab kev sib txuas lus kho qhov muag.
