Tekinoloje yatsopano ya Dicton Photodtector

Ukadaulo watsopano waWoonda Silicon Photodtector
Zojambulajambula za Photon zimagwiritsidwa ntchito powonjezera kuyamwaSilicon Photodetors
Makina a Photonic akuchulukirachulukira m'mapulogalamu ambiri omwe akutuluka, kuphatikizapo kulumikizana kwamaso, kumverera kwa chivindikiro, komanso kuganiza zamankhwala. Komabe, kukhazikitsidwa kwa zithunzi za Photondonoojambula zithunzi, zomwe zimatengera mtundu wa semiconductor yogwiritsidwa ntchito pacholinga chimenecho.
Pachikhalidwe, Silicon (SI) wakhala semiquonduus kwambiri semicoonductor pamakampani amagetsi, zochuluka kwambiri kuti mafakitale ambiri akhwima kuzungulira nkhaniyi. Tsoka ilo, Siyo ili ndi vuto lofooka lolimba mu infrared (nir) loperim poyerekeza ndi semicondractor ena monga gallium arnide (Gaas). Chifukwa cha izi, Gaas ndi oyang'anira otchuka akukonzekera kugwiritsa ntchito zithunzi koma sizigwirizana ndi zochitika zachikhalidwe zachitsulo-oxide semiconductor (cmos) machitidwe omwe amagwiritsidwa ntchito popanga magetsi ambiri. Izi zinapangitsa kuti pakhale kuwonjezeka koopsa pamatumba awo opanga.
Ofufuzawo adapanga njira yopititsira patsogolo mayamwidwe a infor-infraton, omwe angayambitse kuchepa kwa zinthu zambiri, ndi gulu lofufuzira la UC lomwe likuchita upainiya njira yatsopano yosinthira mafilimu owonda. M'mapepala awo aposachedwa kwambiri ku Nexus Nexus, akuwonetsa kwa nthawi yoyamba kuwonetsa chithunzi choyeserera cha Sinayi ndi micrododing incraction - ndi Nano-mawonekedwe ena a III-V Gulu Semonductors. Photoodtector imakhala ndi cylindrical diicon mbale yoyikidwa pamtunda wa inlic yolowera, yokhala ndi "zala" zopitilira muyeso pazala chala pazachitsulo cholumikizira pamwamba pa mbale. Chofunika, silika wowuma chimadzaza mabowo ozungulira omwe amakonzedwa munthawi ya nthawi yomwe imakhala ngati masamba a Photon. Kapangidwe kakang'ono ka chipangizocho kumapangitsa kuti mawonekedwe omwe nthawi zambiri amawonera pafupi ndi 90 ° pomwe igunda pamwamba, kuloleza kungofalikira pambuyo pake. Kufalikira kwa mitundu iyi kumawonjezera kutalika kwa maulendo a kuwala ndikuchepetsa, kumapangitsa kuti zikhale zowunikira zambiri motero zimakulitsa mayamwidwe.
Ofufuzawo amachititsanso mawonetseresi komanso kusanthula kwachidziwitso kuti amvetsetse mavuto omwe zotsatira za ma Photon, ndikuchita zoyeserera zingapo poyerekeza zithunzi ndi iwo. Adapeza kuti Photon agwidwa ndi kusintha kwakukulu mu kuyankha kwamphamvu kwa NIR Spectrum, kukhala pamwamba pa 68% ndi nsonga ya 86%. Ndikofunika kudziwa kuti mgulu la pafupi kwambiri, kuyamwa kwa chithunzi cha zithunzi ndi kangapo kuposa kwa silika wamba, gallium yaposachedwa. Kuphatikiza apo, ngakhale kuti kapangidwe kakupangidwira ndi 1μm Giln, mafani a 30 NM ndi 100 NM And 100 NM Silicon Films Ogwirizana ndi Magetsi a CMOS amawonetsa momwemo.
Ponseponse, zotsatira za phunziroli zikuwonetsa njira yolonjeza kusintha mafashoni a Silicon pakusintha mapulogalamu a Photosnasics. Mayamwa kwambiri amatha kukwaniritsidwa ngakhale mu disilitilo yopyapyala, ndipo parasitic ya madera amatha kuchepetsedwa, yomwe ndi yovuta kwambiri. Kuphatikiza apo, njira yomwe ikuphatikizidwa ndiyogwirizana ndi njira zamakono zopangira ma CMOS ndipo chifukwa chake amatha kusintha momwe ma Oftoctroctics amaphatikizira m'magawo achikhalidwe. Izi, zitha kusintha njira yolowera kwambiri pakompyuta yamakompyuta yoyipitsa ndi luso loyerekeza.
