Kwicandelo lokuxoxa ngezinto ze-elektroniki, iifoto ezingathandabuzekiyo zihlala zibalulekile.Imigaqo yawo yokusebenza kunye neeparamitha zentsebenzo zichaphazela ngqo ukusebenza kunye nokuchaneka kwezicelo ezinjengee-fotopitric kunye neenkqubo zokulawula ngokuzenzekelayo.Eli nqaku lijolise ekunikezeleni ngohlalutyo olunzulu lweempawu ezisisiseko zabafotisi kunye neeparamitha eziphambili, zibonelela ngesikhokelo esibanzi nesine-in-in-in-in-in-in-in-in-in-in-ract yeenjineli kunye nabasebenzi be-R & D.
Ukungaxhathisi obumnyama kunye nokuxhathisa ukukhanya: Iimpawu zefoto zefoto
Umgaqo wokuSebenza weFotoresistor usekwe kutshintsho lwayo kwimvakalelo yokukhanya.Ngaphantsi kombane (ubumnyama opheleleyo), ixabiso lemifanekiso ekwakufikelela kwixabiso eliphezulu, elibizwa ngokuba kukungaxhathisi obumnyama, kwaye okwangoku kubizwa ngokuba bubumnyama bobumnyama.Ukuthatha i-MG41-21 Ifoto zikaMfanekiso, ixabiso laso eliPhezulu lingaphezulu okanye lilingana no-0,1mω, libonisa ukuba ukugeleka kwangoku ngemeko emnyama incinci kakhulu.Kungenxa yokuba ukuqhubela kwento yokufota i-Stoforsunstosensi ikhula kakhulu ngokungabikho kokukhanya.Ngokuchasene noko, kwindawo enokukhanya, ixabiso lokuchasana nefonti lempheuko ihla kakhulu, ukufikelela kwixabiso elibizwa ngokuba lixabiso elibiweyo, kwaye okwangoku kuyabizwa ngokuba kwangoku.Umzekelo, ixabiso elikhanyayo lemodeli efanayo yefoto phantsi kweemeko zokukhanya iphantsi okanye ilingana ne-1Kω, ebonisa ukuphucuka okukhulu kweemeko zokukhanya.Lo mahluko phakathi kokuxhathisa obumnyama kunye nokuxhathisa ukukhanya sisibonakaliso esibalulekileyo sobuntunumli bomfanekiso.Ngokufanelekileyo, ixabiso lokuchasana nobumnyama liphezulu kwaye ixabiso lokukhanya lokukhanya liphantsi ukuqinisekisa ukuba ifoto yophengululi inesimo esifanelekileyo phantsi kweemeko zokukhanyisa.
Iimpawu ze-Volt-Ampere: Ipharamitha ebalulekileyo echaza ubudlelwane phakathi kwe-voltage nangoku
Uhlobo lwe-volt-Amprere of ifoto yefoto yiparamitha echaza ubudlelwane phakathi kwe-voltage ngaphaya komvuzo wakho kunye nokurhoxa malunga nemeko yokukhawulezisa.Olu phawu alutyhila nje iimpawu zempendulo zefoto, kodwa ikwayisalathiso ebalulekileyo xa uyila iifolda zokwenyani.I-volt-Ampere curve ijikajika inokubonelela ngeenjineli ngemeko yokusebenza komvuzo ophantsi kwe-voltages eyahlukileyo, kwaye emva koko yandisa uyilo lwesekethe ukuze kulungelelaniswe kwiimfuno ezithile zesicelo.
Ipropathi ebonakalayo: Eyona nto iphambili ekukhetheni izinto ezifotileyo
Ukukhanya kwamaza ahlukeneyo aneempembelelo ezahlukeneyo kwifoto, ezibizwa ngokuba ziimpawu ezibonakalayo.Iimpawu ezibonakalayo azibonakalisi nje imvakalelo yokuphendula yefowuni yokukhanya kwezaphulelo ezithile, kodwa ikwabonelela ngesiseko esibalulekileyo sokukhethwa kwezixhobo zefonti kwizicelo ezithile zefonti kwizicelo ezithile zefonti kwizicelo ezithile zefonti kwizicelo ezithile zefonti kwizicelo ezithile zefonti kwizicelo ezithile zefonti kwizicelo ezithile zefonti kwizicelo ezithile zefonti kwizicelo ezithile zefonti kwizicelo ezithile zefonti kwizicelo ezithile zefonti kwizicelo ezithile zefonti kwizicelo ezithile zefonti kwizicelo ezithile zefoto kwizicelo zefoto.Umzekelo, i-cadmim ye-cadmim ye-sulfide inomdla kakhulu kwingingqi ebonakalayo yokukhanya, ngelixa i-Coulfide ifoto ibonisa ubuntununtunu obuphezulu kwingingqi ye-infrared.Ke ngoko, ukukhetha izinto ezifanelekileyo zefonti esekwe kwiimpawu zomthombo wokukhanya kwisicelo sisitshixo sokufezekisa ukuguqulwa ngokufanelekileyo kwefoto.
Iimpawu ze-frequency: umlinganiso wesantya sokuphendula somfanekiso
Iimpawu eziphindaphindiweyo zefotosiregcini zichaza ukuba iphendula njani ngokukhawuleza kwiinguqu kubunzulu bokukhanya.Iifoto zezinto ezahlukeneyo zinemilinganiselo yokuphendula rhoqo, echaphazela ngqo ukusetyenziswa kweefoto eziphantsi kweemeko zokukhanyisa.Ixesha lokulibaziseka, oko kukuthi, ixesha elithathayo ukuba ifophethi ifumane utshintsho ekukhanyeni kwaye uzinze ngoku, yinto ebalulekileyo yeempawu zendlela.Nangona ixesha elikhulu lokulibaziseka kwiimpawu ezininzi zefoto zabafotisi zinciphisa ukusetyenziswa kwabo kwizicelo eziziintloko, lo mda ungayiswa ngokuyinxenye ngokukhetha izinto zokuphendula ngokukhawuleza.
Ngokuqonda okunzulu kwezi mpawu zisisiseko kunye neeparamitha eziphambili zefoto, abaphuhlisi kunye neenjineli zinokukhetha kwaye bayile iifoto ezifanelekileyo kwiimfuno zabo zemali ezifanelekileyo.Ngenxa yesi siseko, kudityaniswe neembono zoyilo ezinobugcisa kunye nezisombululo zobugcisa eziphambili, ukusebenza kunye nokuthembeka kunye nokuthembeka kwenkqubo yokuziva ifoto kunokuphuculwa ngokufanelekileyo kwaye kukhuthaza ukuphuculwa kwetekhnoloji yecandelo le-elektroniki.
