Kuchuluka kwa mawonekedwe a Photodtector amaphwanya malire

Malinga ndi akatswiri azachuma a Gunken Actwork posachedwapa adanenanso kuti ofufuza a Finland apanga chithunzi chakuda ndi kuchuluka kwa zida za 30%, zomwe ndi nthawi yomwe ikuyenera kugwiritsidwa ntchito kwambiri m'magalimoto, mafoni am'manja, ma traces anzeru ndi zida zamankhwala.

Photodoctoct ndi sensor yomwe imatha kuyeza kuwala kapena mphamvu zina zamagetsi, sinthani zithunzi m'makono, ndipo zithunzi zoyamwa zimapanga ma elekitironi. Photoodtector imaphatikizapo Photothide ndi Phototransistor, etc. Njira zambiri zimagwiritsidwa ntchito pofotokoza kuchuluka kwa matope omwe amaperekedwa ndi ma elekitiro a electrogetrib, omwe amaphatikizidwa ndi kuchuluka kwa zithunzi zomwe zidagawidwa.

Phototoni atakumana ndi gawo la electron kupita kudera lakunja, kuchuluka kwa kuchuluka kwa chipangizocho ndi 100% (komwe kumaganiziridwa kale kuti ndi malire). Mu phunzilo laposachedwa kwambiri, chithunzi chakuda cha silicon chinali ndi mphamvu mpaka 130 peresenti, zomwe zikutanthauza kuti zithunzi chimodzi zimatulutsa ma elekitala 1.3.

Malinga ndi akatswiri ofufuza a Aalto University, chida chachinsinsi chomwe chimayambitsa kuzengereza kwakukulu komwe kumachitika mkati mwatsopano kamene kankhani wakuda wa silicon, womwe umayambitsidwa ndi zithunzi zazitali. M'mbuyomu, asayansi sanathe kuwona zodabwitsazi m'magulu enieni chifukwa kupezeka kwa magetsi ndi kuwala kochepa kunachepetsa kuchuluka kwa ma elekitoni omwe adasonkhanitsidwa. "Zipangizo zathu zomwe zidabwezedwa sizibwezeredwa komanso zotayika zilizonse, motero titha kusonkhanitsa onyamula oyang'anira a Hera.

Kuchita bwino kumeneku kwatsimikiziridwa ndi Institute of Technology ya Germany National Metrology Society (PTB), ntchito yolondola komanso yodalirika ku Europe.

Ofufuzawo amati njira yolemba pankhaniyi imatanthawuza kuti asayansi amatha kusintha magwiridwe antchito a zojambulajambula.

"Zowunikira zathu zapanga chidwi kwambiri, makamaka m'malo a ma biotechchlogy ndi makina oyang'anira mafakitale," anatero Dr. Mikko Junta, Chuma cha Elfysin, kampani yomwe ili ndi University. Amanenedwa kuti ayamba kupanga zofuna za malonda.
