Kwadalwa ngo 2025.12.03
Ikhono lokubona ebusuku liyisici esibalulekile kumamojula emakhamera anamuhla, kungakhathaliseki ukuthi kusekelwe ekuqapheleni kwezokuphepha, ezithombeni ze-astronomy, noma ezithombeni zezimboni. Ezimeni zokukhanya okuphansi, iningi lezinzwa libhekana nezinkinga zokuphazamiseka, imininingwane ehlanzekile, kanye nokungabikhona kahle kokukhanya kwe-infrared—izinkinga ezenza ukuthi izithombe zingabi usizo ezinhlelweni ezibalulekile. Faka phakathi le-Sony IMX585 ikhamera module: umphumela omusha ekusebenzeni kokubona ebusuku, okwenziwa nge-Sony's Starvis 2 technology futhi kwakhiwe ukuze kubhekwe izithiyo eziyisisekelo ze-sensors yemifanekiso yendabuko. Ngokwehlukana nezizukulwane zayo, i-IMX585 ayigcini ngokuthwebula imifanekiso emnyama; iletha ividiyo ecacile, enemininingwane, futhi enembile ngemicibisholo ethile eguqula lokho okungenzeka ezimeni zokukhanya okuphansi kanye ne-infrared eduze (NIR). Kulesi sihloko, sizohlukanisa izinguquko zobuchwepheshe kanye nezinzuzo zangempela ezenza i-IMX585 ibe yisibonelo esihle samamojula amakhamera okubona ebusuku.
I-Fondation: I-Sony Starvis 2 Technology kanye ne-Near-Infrared Sensitivity
Enhliziyweni yokubona ebusuku ye-IMX585 kukhona ubuchwepheshe be-Sony obubizwa nge-Starvis 2, okuyisikhumbuzo esikhethekile esihlelwe ukuze sibe ne-sensitivity ephezulu ezindaweni ezinemibala ephansi. Lokhu kuhlukanisa le sensor nezinye ezijwayelekile kukhono lwayo lokwandisa ukuhlanganiswa kokukhanya—ikakhulukazi emkhakheni we-near-infrared—ngaphandle kokwehlisa ikhwalithi yesithombe. I-IMX585 inezinga elithuthukisiwe le-1.7x ku-NIR sensitivity uma kuqhathaniswa ne-IMX485, okukhombisa intuthuko eqondile ekutholeni izithombe ezicacile zokubona ebusuku ezimeni lapho ukukhanya kwe-infrared kuyinsiza yokukhanyisa eyinhloko (isb. amakhamera okuphepha ane-IR LEDs noma i-astrophotography yezinto ezisemkhathini).
I-Quantum efficiency (QE)—ukulinganisa ukuthi i-sensor ikwazi kanjani ukuguqula ukukhanya ibe izimpawu zikagesi—iqinisa kakhulu ubuhlakani be-IMX585. Ifinyelela ku-92% peak QE ebangeni lokukhanya okubonakalayo kanye no-60% ebangeni le-near-infrared. Ukuze kuqondiswe, ama-sensor amaningi wezinga labathengi ahamba cishe phakathi kuka-60-70% QE ekukhanyeni okubonakalayo futhi ngaphansi kuka-40% ku-NIR, okusho ukuthi i-IMX585 ibamba cishe konke ukukhanya okukhona ezindaweni ezimnyama. Lokhu kubaluleke kakhulu kumakhamera ezokuphepha, lapho ukuthola ubuso noma amakhodi ezinombolo ebusuku kuncike ekutholeni ukujikeleza okuncane kwe-infrared, noma kumarigi e-astrophotography afana ne-QHYCCD miniCAM8, esebenzisa i-IMX585 ukubamba imininingwane ye-deep-space engabonakali kumasensor aphansi.
Ukwakhiwa komzimba kwesensori nakho kudlala indima ebalulekile. Ngesayizi yesensori engu-1/1.2-intshi kanye ne-pixel pitch engu-2.9μm, i-IMX585 inezinhlayiya ezinkulu kuneziningi zezinsiza ezincane, okuvumela ukuthi ngayinye i-pixel iqoqe ukukhanya okuningi. Izinhlayiya ezinkulu zinciphisa umsindo futhi zithuthukisa ubudlelwano phakathi kwesignali nomsindo (SNR)—izici ezimbili ezenza noma ziphule ukujula kokubona ebusuku. Ngenkathi izinhlayiya ezincane zivamile kumakhamera abathengi anama-megapixel aphezulu, zifaka engozini ukusebenza kokukhanya okuphansi; i-IMX585 ifinyelela ibhalansi phakathi kokuxazulula (8.41 ama-megapixels) kanye nekhono lokuqoqwa kokukhanya, okwenza kube kuhle kwezicelo zobungcweti lapho imininingwane nokusebenza kokumnyama kungavunyelwa.
Ububanzi Obushintshashintshayo kanye ne-HDR: Ukugcina Imininingwane Ekuphikisaneni Okukhulu
Ukubona ebusuku akukhona nje kuphela ukubona emnyama—kukhona futhi ukuthwebula imininingwane ezinkundleni ezinezinhlangothi eziphakeme, njengomgwaqo okhanyisiwe kancane onomlampu ophakeme noma isibhakabhaka esinezinkanyezi nesakhiwo esikhanyisiwe phambili. I-IMX585 ikhangwa lapha ngekhono layo eliphezulu lokuhamba (HDR), elivulwa nge-dual gain HDR kanye ne-digital overlap HDR. Kumodi yokuthwebula eyodwa, iletha ibanga le-88 dB, futhi kumodi yokuthwebula eminingi, lokhu kukhuphuka kube yi-106 dB eyamangalisa. Kubasebenzisi bokugcina, lokhu kusho ukuthi awekho ama-highlights aphukile noma ama-blacks aphukile ezithombeni zobusuku; imininingwane efana nezingubo zomuntu ophumayo noma ubukhazikhazi bendlu ibonakala ngisho noma ingxenye yesithombe ikhuluma emthunzini kanti enye ikukhanyeni kwe-IR okuqondile.
QHYCCD’s miniCAM8, ikhamera ethandwayo yokuthwebula izithombe zezinkanyezi eyakhiwe phezu kwe-IMX585, ithatha lesi sinyathelo phambili nge-Linearity HDR mode yayo. I-IMX585’s native 12-bit depth ingakhawulela ububanzi obuphilayo, kuholele ezinkingeni zokuhluka kwemibala, ngakho-ke i-QHYCCD ihlanganise ukwanda okuphezulu nokuphansi ukuze wandise idatha ibe ngu-16-bit futhi yathuthukisa i-algorithm yokulungisa ukulingana. Umphumela? Ububanzi obuphilayo buka-46,300:1 (93 dB noma ama-stop angu-15.5), umthamo ophelele we-well ka-46 ke⁻, kanye noise yokufunda ephansi njenge-1.0 e⁻. Noise yokufunda—i-noise kagesi efakwa lapho kushintshwa idatha ye-pixel ibe izimpawu zedijithali—iyisitha esikhulu sokubona ebusuku, futhi i-IMX585’s ultra-low read noise iqinisekisa ukuthi ngisho nezimpawu zokukhanya ezincane kakhulu zigcinwa ngaphandle kokuphazamiseka. Kubathwebuli bezithombe zezinkanyezi, lokhu kusho ukuthwebula ama-nebulae anokukhanya okuncane ngaphansi kwesibhakabhaka esimnyama ngaphandle kokuphazamiseka kwezinhlaka; kumasistimu okuphatha, kusho ukuthi kukhona ividiyo ecacile yezinto ezihambayo emnyama kakhulu.
Ukusebenza Kwangempela: Kusuka KumaKhamera Okuphepha Kuya Ku-Astroimaging
Amandla okubona ebusuku e-IMX585 awawona ama-theory kuphela—awafakazelwa ezinhlelweni zangempela ezimbonini. Ake sihlole izimo ezimbili ezibalulekile zokusebenzisa lapho amandla wesensori ekhanya kakhulu:
1. Ukuvikeleka kanye Nokubhekwa Kwezimboni
