Ibisubizo biheruka by'ubushakashatsi bwakozwe n'ibikoresho bipima imiterere y'ibinyabuzima

Abashakashatsi bakoze kandi bagaragaza urumuri rushya rw'icyatsi kibisi rufata utwuma duto duto tw’umwimerere dukoresha ikoranabuhanga rya CMOS. Gushyiramo utwuma duto duto dukoresha ikoranabuhanga rya silicone hybrid image sensors bishobora kuba ingirakamaro kuri porogaramu nyinshi. Izi porogaramu zirimo kugenzura umuvuduko w'umutima ukoresheje urumuri, kumenya ibikumwe n'ibikoresho bipima ibintu biri hafi aho.

Byaba bikoreshwa muri telefoni zigezweho cyangwa kamera za siyansi, inyinshi mu byuma bipima amashusho muri iki gihe bishingiye ku ikoranabuhanga rya CMOS n'ibikoresho bipima amashusho bidashingiye ku binyabuzima bihindura ibimenyetso by'urumuri mo ibimenyetso by'amashanyarazi. Nubwo ibikoresho bipima amashusho bikozwe mu bikoresho by'umwimerere bikurura abantu kuko bishobora gufasha kunoza ubushobozi bwo kumva, kugeza ubu byaragoye gukora ibikoresho bipima amashusho bidashingiye ku binyabuzima bifite ubushobozi bwo hejuru.

Umushakashatsi wungirije Sungjun Park, wo muri Kaminuza ya Ajou muri Koreya y'Epfo, yagize ati: “Gushyiramo ibikoresho bipima imiterere y’ibinyabuzima mu bikoresho bipima amashusho bya CMOS bisaba ibikoresho bipima urumuri rw’ibinyabuzima byoroshye gukora ku rwego runini kandi bishobora kumenya amashusho neza kugira ngo bikore amashusho asobanutse neza ku gipimo cyo hejuru mu mwijima. Twakoze photodiode z’umwimerere zibonerana kandi zigaragaza icyatsi kibisi zishobora kuzuza ibi bisabwa.”

Abashakashatsi basobanura uburyo bushya bwo gupima amashusho y’umwimerere mu kinyamakuru Optica. Banakoze sensor ya hybrid RGB imaging bashyiramo photodetector y’umwimerere ibonerana ifata amashusho y’umwimerere ku gikoresho cya silicon photodiode gifite filters zitukura n’ubururu.

Kyung-Bae Park, umuyobozi wungirije w’itsinda ry’ubushakashatsi ryo mu Kigo cya Samsung Advanced Institute of Technology (SAIT) cyo muri Koreya y’Epfo, yagize ati: “Kubera ko hashyizweho urwego rw’ubuvanganzo bw’umwimerere, urwego rw’umwimerere ruhitamo icyatsi kibisi rukoresha muri izi sensors z’amashusho rugabanya cyane uburyo bwo kuganira hagati y’amabara atandukanye, kandi iyi miterere mishya ishobora gutuma photodiode nziza z’umwimerere ziba igice cy’ingenzi cya modules z’amashusho na photosensors ku bikorwa bitandukanye.”

Udukoresho twinshi dukoresha ikoranabuhanga rigezweho mu gupima imiterere y'ibinyabuzima

Ibikoresho byinshi by’umwimerere ntibikwiriye gukorwa ku bwinshi bitewe nuko bishobora kwihanganira ubushyuhe. Ntibishobora kwihanganira ubushyuhe bwinshi bukoreshwa nyuma yo kuvurwa cyangwa ngo bigire ihindagurika iyo bikoreshejwe ku bushyuhe buringaniye igihe kirekire. Kugira ngo batsinde iki kibazo, abahanga mu bya siyansi bibanze ku guhindura urwego rw’icyuma gipima imiterere y’icyuma gipima imiterere y’ikirere kugira ngo bongere ubushobozi bwo gupima, gukora neza no kumenya. Uburyo bwo kumenya imiterere y’ikintu ni igipimo cy’uburyo icyuma gipima imiterere y’ibimenyetso bidakomeye. Sungjun Park yagize ati: “Twashyizeho umurongo w’umuringa wo mu mazi (BCP): urwego rw’icyuma gipima imiterere y’amashanyarazi nk’urwego rwo gutwara amashanyarazi, rutanga imiterere yihariye y’icyuma gipima imiterere y’ikirere, harimo imikorere myiza cyane n’umuraba uri hasi cyane, bigabanya urusaku.” Ikigo gipima imiterere y’ikirere gishobora gushyirwa kuri silicon photodiode ifite filteri zitukura n’ubururu kugira ngo hakorwe icyuma gipima imiterere y’imiterere y’icyuma gipima ...

Abashakashatsi bagaragaje ko icyuma gishya gipima amashusho kigaragaza igipimo cyo kuvumbura gihwanye n’icya silicon photodiode isanzwe. Iki cyuma cyakoze amasaha 2 mu buryo buhamye ku bushyuhe buri hejuru ya 150 °C kandi cyagaragaje ko kidahinduka mu mikorere mu gihe kirekire mu minsi 30 kuri 85 °C. Ibi byuma bipima amashusho bigaragaza kandi imikorere myiza y’amabara.

Hanyuma, barateganya guhindura ibikoresho bishya bipima amashusho n'ibipima amashusho bivanze ku buryo bikoreshwa mu buryo butandukanye, nko mu bikoresho bigendanwa n'ibipima amashusho (harimo n'ibipima amashusho bya CMOS), ibipima hafi y'aho umuntu aherereye, n'ibikoresho by'intoki biri ku mashusho.
