25/07/29Pankhani za kuyerekezera kwa bioluminescence komanso kuzindikira kwamphamvu kwambiri kwa mafakitale, kupeza bwino pakati pa liwiro la kujambula ndi kukhudzika kwakhala nthawi yayitali yolepheretsa kupita patsogolo kwaukadaulo. Mayankho achikale a mizera kapena madera nthawi zambiri amakumana ndi zovuta kusinthanitsa, zomwe zimapangitsa kuti zikhale zovuta kuti azitha kuzindikira bwino komanso momwe makina amagwirira ntchito. Zotsatira zake, kukweza kwa mafakitale kwakhala kovuta kwambiri.
Kukhazikitsidwa kwaukadaulo wowunikira kumbuyo kwa TDI-sCMOS kwayamba kuthana ndi izi. Ukadaulo wotsogolawu sikuti umangothana ndi zofooka zakuthupi za kujambula kothamanga kwambiri m'malo opepuka komanso umakulitsa ntchito zake kupitilira sayansi yamoyo kupita kumagulu apamwamba a mafakitale monga kuyesa kwa semiconductor ndi kupanga molondola. Ndizitukukozi, TDI-sCMOS ikukhala yofunika kwambiri pakugwiritsa ntchito zithunzi zamakono zamafakitale.
Nkhaniyi ikufotokoza mfundo zazikuluzikulu za kujambula kwa TDI, kutsata kusinthika kwake, ndikukambirana za kukula kwake pamakina opanga mafakitale.
Kumvetsetsa Mfundo za TDI: Kupambana Kwambiri mu Kujambula Kwamphamvu
Time Delay Integration (TDI) ndiukadaulo wopezera zithunzi potengera mfundo yosanthula mizere yomwe imapereka zida ziwiri zofunika kwambiri:
Synchronous Dynamic Acquisition
Mosiyana ndi makamera am'deralo omwe amagwira ntchito mozungulira "stop-shot-move", masensa a TDI amawonetsa mosalekeza zithunzi zikuyenda. Pamene chitsanzocho chikuyenda m'malo owonera, sensa ya TDI imagwirizanitsa kayendedwe ka pixel ndi liwiro la chinthucho. Kulumikizana kumeneku kumathandizira kuwonekera kosalekeza komanso kuchuluka kwamphamvu kwa chinthu chomwecho pakapita nthawi, kulola kujambula bwino ngakhale pa liwiro lalikulu.

Kuchulukitsa kwa Domain
Mzere uliwonse wa pixel umasintha kuwala kobwera kukhala magetsi, komwe kumakonzedwa kudzera mu magawo angapo owerengera. Kuchulukitsa kosalekeza kumeneku kumakulitsa bwino chizindikiro chofooka ndi gawo la N, pomwe N imayimira kuchuluka kwa magawo ophatikizika, kuwongolera chiŵerengero cha signal-to-noise ratio (SNR) pansi pa kuyatsa kochepa.
Chithunzi cha Ubwino wa Zithunzi Pamagawo Osiyanasiyana a TDI
Kusintha kwaukadaulo wa TDI: Kuchokera ku CCD kupita ku Back-Illuminated sCMOS
Masensa a TDI adamangidwa poyamba pa CCD kapena nsanja za CMOS zowunikira kutsogolo, koma zomangamanga zonsezo zinali ndi malire pamene zikugwiritsidwa ntchito pazithunzi zofulumira komanso zochepa.
TDI-CCD
Zowunikira kumbuyo za TDI-CCD zowunikira zimatha kukwaniritsa quantum efficiencies (QE) pafupi ndi 90%. Komabe, kamangidwe kawo ka ma serial readout amaletsa kuthamanga kwa kujambula - mizere ya mizere nthawi zambiri imakhala pansi pa 100 kHz, yokhala ndi masensa a 2K-resolution omwe amagwira ntchito pafupifupi 50 kHz.
Front-Illuminated TDI-CMOS
Zowunikira zowunikira kutsogolo za TDI-CMOS zimapereka liwiro la kuwerenga mwachangu, mizere ya 8K-resolution imafika mpaka 400 kHz. Komabe, zinthu zomangika zimalepheretsa QE yawo, makamaka muufupi wamtali wamtali, nthawi zambiri amasunga pansi pa 60%.
Kupita patsogolo kodziwika kudadza mu 2020 ndikutulutsidwa kwa Tucsen'sDhyana 9KTDI sCMOS kamera, kamera yowunikira kumbuyo ya TDI-sCMOS. Zimawonetsa kudumpha kwakukulu pakuphatikiza kukhudzika kwakukulu ndi magwiridwe antchito a TDI othamanga kwambiri:
-
Kuchita Bwino kwa Quantum: 82% pachimake cha QE-pafupifupi 40% kuposa masensa wamba omwe amawunikira kutsogolo kwa TDI-CMOS, ndikupangitsa kuti ikhale yabwino kwa kujambula kopepuka.
-
Mzere wa Mzere: 510 kHz pa 9K resolution, kumasulira kwa data ya 4.59 gigapixels pa sekondi iliyonse.
Ukadaulowu udayamba kugwiritsidwa ntchito pakuwunika kwapamwamba kwambiri, pomwe kamera idajambula chithunzi cha 2-gigapixel cha chitsanzo cha fulorosenti ya 30 mm × 17 mm mumasekondi 10.1 pansi pamikhalidwe yokhathamiritsa, kuwonetsa kupindula kwakukulu pakujambula mwachangu komanso kukhulupirika mwatsatanetsatane pamakina odziwika bwino amderali.

Ubwino waukulu wa TDI Technology
Kumverera Kwambiri
Masensa a TDI amadziunjikira ma siginecha pamawonekedwe angapo, kupititsa patsogolo magwiridwe antchito a kuwala kochepa. Ndi masensa ounikira kumbuyo a TDI-sCMOS, kuchuluka kwachulukidwe kopitilira 80% kumatheka, komwe kumathandizira ntchito zovuta monga kujambula kwa fluorescence ndikuwunika kwamdima.
Kuthamanga Kwambiri
Masensa a TDI amapangidwa kuti azijambula mokweza kwambiri, kujambula zinthu zoyenda mwachangu momveka bwino. Mwa kulunzanitsa kuwerengera kwa pixel ndi kusuntha kwa chinthu, TDI imachotsa kusasunthika koyenda ndikuthandizira kuwunika kotengera ma conveyor, kusanthula zenizeni zenizeni, ndi zochitika zina zapamwamba.
Kusintha kwa Signal-to-Noise Ratio (SNR)
Mwa kuphatikiza ma siginecha pamagawo angapo, masensa a TDI amatha kupanga zithunzi zapamwamba kwambiri zokhala ndi zowunikira pang'ono, kuchepetsa kuwopsa kwa kujambula zithunzi m'zitsanzo zachilengedwe ndikuchepetsa kupsinjika kwa kutentha muzinthu zovutirapo.
Kuchepetsa Kusavutitsidwa ndi Kusokoneza Kozungulira
Mosiyana ndi makina ojambulira madera, masensa a TDI sakhudzidwa kwambiri ndi kuwala kozungulira kapena mawonedwe chifukwa cha mawonekedwe awo osakanikirana a mzere ndi mzere, kuwapangitsa kukhala olimba kwambiri m'madera ovuta a mafakitale.
Chitsanzo cha Ntchito: Kuyang'ana Wafer
M'gawo la semiconductor, makamera amtundu wa sCMOS nthawi zambiri amagwiritsidwa ntchito pozindikira kuwala kochepa chifukwa cha liwiro lawo komanso kukhudzika kwawo. Komabe, machitidwewa akhoza kukhala ndi zovuta zake:
-
Mawonekedwe Ochepa: Mafelemu angapo amayenera kusonkhanitsidwa palimodzi, zomwe zimapangitsa kuti ziwononge nthawi.
-
Kusanthula Pang'onopang'ono: Kujambula kulikonse kumafunika kudikirira kuti siteji ikhazikike musanajambule chithunzi chotsatira.
-
Zomangamanga: Mipata yazithunzi ndi zosagwirizana zimakhudza mtundu wa sikani.
Kujambula kwa TDI kumathandizira kuthana ndi zovuta izi:
-
Kusanthula mosalekeza: TDI imathandizira masikeni akulu, osasokonekera popanda kufunikira kosoka chimango.
-
Kupeza Mwachangu: Mizere yokwera (mpaka 1 MHz) imachotsa kuchedwa pakati pa kujambula.
-
Chifaniziro cha Zithunzi Zowongoleredwa: Njira yojambulira mzere ya TDI imachepetsa kupotoza kwamawonekedwe ndikuwonetsetsa kulondola kwa geometric pa sikani yonse.
TDI VS Area Scan
Chitsanzo: TDI imathandizira kuti pakhale njira yopitilira komanso yosalala yopezera
Kamera ya Tucsen ya Gemini 8KTDI sCMOS yakhala yothandiza pakuwunika kozama kwa ultraviolet wafer. Malinga ndi kuyesa kwamkati kwa Tucsen, kamera imakwaniritsa 63.9% QE pa 266 nm ndipo imasunga kutentha kwa chip pa 0 ° C pakugwiritsa ntchito nthawi yayitali - yofunikira pakugwiritsa ntchito kwa UV-sensitive.
Kukulitsa Kugwiritsa Ntchito: Kuchokera Kujambula Kwapadera Kufikira Kuphatikiza System
TDI sikulinso kumangogwiritsa ntchito niche kapena kuyesa benchmark. Cholinga chasinthira ku kuphatikiza kothandiza mu machitidwe a mafakitale.
Tucsen's Gemini TDI mndandanda umapereka mitundu iwiri yamayankho:
1. Zithunzi za Flagship: Zapangidwa kuti zigwiritsidwe ntchito zapamwamba monga kuyang'ana kutsogolo kwa wafer ndi kuzindikira kwa UV. Zitsanzozi zimayika patsogolo kukhudzidwa kwakukulu, kukhazikika, ndi kupititsa patsogolo.
2. Zosiyanasiyana za Compact: Zing'onozing'ono, zoziziritsa mpweya, ndi mphamvu zochepa-zoyenera kwambiri kwa machitidwe ophatikizidwa. Zitsanzozi zikuphatikizapo ma CXP (CoaXPress) othamanga kwambiri kuti azitha kugwirizanitsa.
Kuchokera pamalingaliro apamwamba kwambiri mu sayansi ya moyo mpaka kuwunika kolondola kwa semiconductor, TDI-sCMOS yowunikira kumbuyo ikuchita gawo lofunikira kwambiri pakupititsa patsogolo mayendedwe azithunzi.
FAQs
Q1: Kodi TDI imagwira ntchito bwanji?
TDI imagwirizanitsa kusuntha kwa mtengo m'mizere ya pixel ndikusuntha kwa chinthucho. Pamene chinthucho chikuyenda, mzere uliwonse umasonkhanitsa kuwonetseredwa kwina, kuonjezera kukhudzika, makamaka pamagetsi otsika komanso othamanga kwambiri.
Q2: Kodi luso la TDI lingagwiritsidwe ntchito pati?
TDI ndiyabwino pakuwunika kwa semiconductor, kuwunika kwa fluorescence, kuyang'ana kwa PCB, ndi mawonekedwe ena apamwamba kwambiri, othamanga kwambiri pomwe kusayenda bwino komanso kuwunika kochepa kumakhala nkhawa.
Q3: Ndiyenera kuganizira chiyani posankha kamera ya TDI yogwiritsa ntchito mafakitale?
Posankha kamera ya TDI, zinthu zofunika zimaphatikizapo kuchuluka kwa mzere, kuchuluka kwachulukidwe, kukonza, kuyankha kwa spectral (makamaka kwa UV kapena NIR applications), komanso kukhazikika kwamafuta.
