Yuav ua li cas xaiv ib tug tshwj xeeb CCD rau microscope?
Cov kev xav tau rau kev kho qhov muag tsom iav pom tau nce siab dua thiab siab dua, thiab cov kev xav tau siab rau CCD cov khoom siv duab kuj tau ua raws. Tau ntsib nrog ntau lub koob yees duab microscope tshwj xeeb CCDs, nws yog qhov nyuaj heev thaum yuav khoom. Yuav xaiv thiab yuav CCD li cas? Cov ntsiab lus twg yuav tsum tau them nyiaj rau?
Ua ntej yuav ib lub microscope-specific CCD, ua ntej nkag siab tias CCD yog dab tsi. CCD yog ib qho khoom siv sib txuas, uas tuaj yeem hu ua CCD duab sensor. Nws yog ib qho khoom siv semiconductor uas tuaj yeem hloov kho cov duab kho qhov muag rau hauv cov teeb liab digital. Cov khoom siv photosensitive me me cog rau ntawm CCD yog hu ua pixel (Pixel). Qhov ntau pixels muaj nyob rau ntawm CCD, qhov siab dua cov duab daws teeb meem nws muab. CCD muaj peb txheej: "me me lens", "xim cais lim", thiab "photosensitive txheej". CCDs tau siv dav hauv kev yees duab digital, astronomy, tshwj xeeb tshaj yog kho qhov muag telemetry, optical thiab spectral telescopes, thiab kev yees duab ceev xws li Lucky imaging.
Thaum muas lub tshuab tsom-iav tshwj xeeb CCD, koj yuav tsum xub qhia meej lub hom phiaj thiab kev siv ntawm kev yuav khoom, thiab xaiv CCD tsim nyog raws li koj xav tau. Nws tsis pom zoo kom ua qhov muag tsis pom kev yuav khoom ntawm lub tshuab ntsuas qhov tshwj xeeb CCD nrog cov pixels siab dhau, tsuav yog nws tsim nyog rau kev siv thiab tuaj yeem ua tiav lub hom phiaj ntawm kev siv. Thaum muas, sim xaiv cov khoom uas muaj qhov sib piv siab, thiab nqaim qhov kev yuav khoom rau koj tus kheej tus nqi puas siab puas ntsws, kom koj tuaj yeem kaw lub hom phiaj sai dua. Koj tuaj yeem xaiv seb puas yuav CCD ua ke nrog lub tshuab tsom iav raws li qhov xav tau tiag tiag. Thaum koj tuaj yeem xyuas kom meej tias nws tuaj yeem siv nrog lub tshuab tsom, koj tuaj yeem yuav CCD koj tus kheej, uas tuaj yeem txo tus nqi zoo.
Lub ntsiab tseem ceeb uas yuav tsum tau them sai sai rau thaum yuav ib lub tshuab tsom-iav tshwj xeeb CCD suav nrog lub cev daws teeb meem, nti loj, pixel loj, teeb liab-rau-suab nrov piv, grey tus nqi, thiab lwm yam. Lub cev kev daws teeb meem yog hais txog kev daws teeb meem ntawm CCD nws tus kheej. Raws li tib lub nti loj, ntau pixels, qhov kev daws teeb meem siab dua. Qhov loj dua qhov loj ntawm CCD nti, qhov zoo dua qhov kev pom zoo. Pixels yog cov chav tsev yooj yim uas tsim cov txheej txheem photosensitive ntawm CCD. Qhov ntau pixels ib cheeb tsam ntawm CCD, qhov kev daws teeb meem siab dua. Qhov siab dua qhov teeb liab-rau-nrawm piv, qhov tseeb thiab pom tseeb dua cov duab zoo. Qhov siab dua tus nqi grey, ntau qib grey lub koob yees duab tuaj yeem paub qhov txawv thiab cov xim ntau dua.
