22/02/25Iyo Quantum Kushanda (QE) ye sensor inoreva mukana wemafotoni anorova sensor ichionekwa mu%. Yakakwira QE inotungamira kune yakanyanya kujeka kamera, inokwanisa kushanda munzvimbo dzakaderera. QE zvakare inotsamira pawavelength, neQE inoratidzwa senhamba imwe chete kazhinji ichireva kukosha kwepamusoro.
Kana mafotoni akarova pixel kamera, mazhinji anosvika panzvimbo inonzwa chiedza, uye anozoonekwa kuburikidza nekuburitsa elekitironi musilicon sensor. Nekudaro, mamwe mafotoni anotorwa, kuratidzwa, kana kuparadzirwa nezvinhu zvekamera sensor isati yaonekwa. Kudyidzana pakati pemafotoni uye zvinhu zvekamera sensor zvinoenderana nephoton wavelength, saka mukana wekuonekwa unoenderana newavelength. Uku kutsamira kunoratidzwa mukamera yeQuantum Efficiency Curve.
Muenzaniso weQuantum Efficiency curve. Tsvuku: Kumashure-kurutivi-yakavhenekerwa CMOS. Bhuruu: Yepamberi Pamberi-yakavhenekerwa CMOS
Akasiyana makamera sensors anogona kuve akasiyana maQEs zvichienderana nekugadzirwa kwavo uye zvinhu. Iyo yakanyanya pesvedzero paQE ndeyekuti sensor yekamera iri kumashure- kana kumberi-kurutivi kwakavhenekerwa. Kumberi-kudivi kwakavhenekerwa makamera, mafotoni anobva kunyaya anofanirwa kutanga apfuura nepagridi yewaya asati aonekwa. Pakutanga, makamera aya aive akaganhurirwa kune quantum efficiencies yeanosvika 30-40%. Kuunzwa kwemamicrolenses kuti atarise chiedza kupfuura waya musilicon inonzwa chiedza kwakasimudza izvi kusvika pa70%. Makamera emazuva ano anovhenekerwa kumberi anogona kusvika peak QEs anosvika 84%. Makamera akavhenekerwa kumashure anodzoreredza dhizaini iyi, ine mafotoni achirova zvakananga kutetepa-yekuona dhizaini yesilicon, pasina kupfuura nepawaya. Aya makamera sensors anopa huwandu hwepamusoro hwekuita kwakatenderedza 95% peak, pamutengo wekuwedzera uye kudhura kwekugadzira maitiro.
Quantum Kubudirira hakuzogara kuine hunhu hwakakosha mune yako yekufungidzira application. Kune maapplication ane yakakwirira mwenje mwero, yakawedzera QE uye sensitivity inopa mukana mudiki. Nekudaro, mumifananidzo yakaderera, yakakwira QE inogona kuburitsa yakagadziridzwa chiratidzo-kune-ruzha-ratio uye mhando yemufananidzo, kana kuderedzwa kuratidzwa nguva yekukurumidza kufungidzira. Asi mabhenefiti epamusoro quantum kunyatsoshanda anofanirwa kuyerwa kutarisana ne30-40% kuwedzera kwemutengo wemashure-akavhenekerwa sensors.
