Abashakashatsi bakoze kandi berekana urumuri rushya rwicyatsi rukurura Photodetector ikorera mu mucyo kandi yunvikana cyane nuburyo bwo gukora CMOS. Kwinjiza fotodetekeri nshya muri silicone hybrid ishusho ya sensor irashobora kuba ingirakamaro kubikorwa byinshi. Izi porogaramu zirimo urumuri rushingiye ku kugenzura umuvuduko wumutima, kumenyekanisha urutoki nibikoresho byerekana ko hari ibintu biri hafi.
Byaba bikoreshwa muri terefone zigendanwa cyangwa kamera za siyanse, ibyuma bifata amashusho muri iki gihe bishingiye ku ikoranabuhanga rya CMOS hamwe na fotodeteri ya organic organique ihindura ibimenyetso by'urumuri mu bimenyetso by'amashanyarazi. Nubwo fotodetekeri ikozwe mubikoresho ngengabuzima ikurura abantu kuko ishobora gufasha kunoza ibyiyumvo, kugeza ubu byagaragaye ko bigoye gukora fotodeteri ikora cyane.
Umushakashatsi ufatanije na Sungjun Park, ukomoka muri kaminuza ya Ajou yo muri Koreya y'Epfo, yagize ati: "Kwinjiza imashini ifotora ibinyabuzima mu byuma bifata amashusho yakozwe na CMOS isaba ibyuma bifata urumuri rworoshye byoroshye gukora ku rugero runini kandi rushobora kumenyekana neza kugira ngo bitange amashusho akarishye ku gipimo cyijimye kandi cyoroshye.
Abashakashatsi basobanura Photodetector nshya mu kinyamakuru Optica. Bakoze kandi ibyuma byerekana amashusho ya RGB yerekana amashusho yerekana icyatsi kibisi gikurura fotodetector kuri fotodiode ya silicon hamwe na filteri itukura nubururu.
Kyung-Bae Park, umuyobozi w’itsinda ry’ubushakashatsi ryaturutse mu Ishuri Rikuru ry’ikoranabuhanga rya Samsung (SAIT) muri Koreya yepfo, yagize ati: “Bitewe n’uko hashyizweho urwego rw’ibinyabuzima bivangavanze, icyatsi kibisi-cyatoranije urumuri rwifashishwa muri ibyo byuma bifata amashusho bigabanya cyane umuhanda uri hagati ya pigiseli zitandukanye z’amabara, kandi iki gishushanyo gishya gishobora gutuma fotodi ikora cyane mu buryo bwerekana amashusho.”
Byinshi mubikorwa bifatika bifotora
Ibikoresho byinshi kama ntibikwiye kubyara umusaruro mwinshi bitewe nubushyuhe bwubushyuhe. Ntibishobora kwihanganira ubushyuhe bwo hejuru bukoreshwa nyuma yo kuvurwa cyangwa guhinduka iyo bikoreshejwe ubushyuhe buke mugihe kirekire. Kugira ngo iki kibazo gikemuke, abahanga mu bya siyansi bibanze ku guhindura urwego rwa fotodetekeri kugira ngo barusheho gushikama, gukora neza, no kumenya. Kumenyekanisha ni igipimo cyerekana uburyo sensor ishobora kumenya ibimenyetso bidakomeye. Parike ya Sungjun igira iti: "Twashyizeho umurongo wo koga wogeramo (BCP): C60 ya bffer ya bffer nk'urwego rwo gutwara ibintu bya elegitoronike, itanga imiterere yihariye ya fotodetektor, harimo gukora neza ndetse n'umuyaga mwinshi cyane, bigabanya urusaku." Photodetector irashobora gushyirwa kuri fotodi ya silicon hamwe na filteri itukura nubururu kugirango ikore sensor ya Hybrid.
Abashakashatsi berekana ko Photodetector nshya yerekana igipimo cyo gutahura ugereranije n’ifoto isanzwe ya silicon. Detector yakoraga amasaha 2 ihagaze hejuru yubushyuhe buri hejuru ya 150 ° C kandi yerekanaga ibikorwa byigihe kirekire kuminsi 30 kuri 85 ° C. Aba Photodetector nabo berekana imikorere myiza yamabara.
Ibikurikira, barateganya guhitamo fotodetekeri nshya hamwe na sensibre yerekana amashusho ya porogaramu zitandukanye, nka sensor igendanwa kandi ishobora kwambarwa (harimo na CMOS yerekana amashusho), ibyuma byegeranye, hamwe nibikoresho byerekana igikumwe kuri disikuru.
