Txhua Yam Koj Yuav Tsum Paub Txog Kab Scan Lub Koob Yees Duab |

Cov koob yees duab scan kab yog cov khoom siv tshwj xeeb uas tsim los ntes cov duab zoo ntawm cov khoom txav los yog txuas mus ntxiv. Tsis zoo li thaj tsam ib txwm siv cov koob yees duab luam theej duab uas ntes 2D duab hauv ib qho kev pom, kab scan koob yees duab tsim cov duab kab los ntawm kab - zoo tagnrho rau cov ntawv thov xws li kev tshuaj xyuas lub vev xaib, kev tshuaj xyuas semiconductor, thiab kev pov thawj ntim.

Cov koob yees duab no feem ntau muaj ib kab ntawm pixels (lossis qee zaum ntau kab), thiab thaum ua ke nrog cov ntsiab lus txav los yog scanning system, lawv tuaj yeem tsim cov duab 2D zoo ntawm cov khoom ntawm txhua qhov ntev. Nyob ntawm seb hom sensor, kab scan koob yees duab feem ntau siv CCD lossis CMOS sensor technology-zoo ib yam li qhov pom hauv ntauCMOS koob yees duab-nrog CMOS dhau los ua qhov kev xaiv uas nyiam vim nws qhov ceev thiab lub zog ua haujlwm.

Lub koob yees duab kab Scan yog dab tsi?

Kab scan koob yees duab feem ntau yog ua kom zoo rau kev lag luam es tsis siv kev tshawb fawb, thiab tej zaum yuav muaj kev txwv rau hauv cov ntawv siv hluav taws xob tsawg lossis ultra-high-precision. Cov suab nrov nyeem ntawv siab, me me pixels thiab feem ntau qis quantum efficiency tuaj yeem txhais tau tias cov koob yees duab no xav tau cov teeb pom kev siab kom xa cov SNR ua haujlwm.

Kab scan koob yees duab tuaj yeem siv ob txoj hauv kev:

1-Dimensional Capture

Cov ntaub ntawv ib-dimensional tuaj yeem ntes tau, xws li hauv daim ntawv thov spectroscopy. Cov txiaj ntsig tau feem ntau sawv cev hauv daim duab hauv lub koob yees duab software, nrog kev siv ntawm y-axis piv rau lub koob yees duab pixel ntawm x-axis.

2-Dimensional Capture

Lub koob yees duab tuaj yeem 'scanned' hla ib qho kev yees duab, los ntawm kev txav lub koob yees duab lossis cov duab thaij duab, thiab cov duab 2-dimensional tuaj yeem tsim los ntawm kev ntes 1-dimensional slices.

Daim ntawv no tso cai rau kev ntes cov duab loj loj hauv qhov ntsuas ntsuas. Lub peev xwm los ntes cov ntsiab lus ntawm kev txav mus los yam tsis muaj suab nrov plooj (lossis dov lub kaw lus artefacts) txhais tau hais tias kab scan koob yees duab feem ntau siv hauv kev lag luam, rau cov kab sib dhos, tshuaj xyuas cov duab loj, thiab ntau dua.

Lub koob yees duab kab Scan ua haujlwm li cas?

Lub koob yees duab scan kab ua haujlwm hauv kev sib koom tes nrog cov khoom txav los yog scanning mechanism. Raws li cov khoom hla hauv qab lub koob yees duab, txhua kab ntawm cov duab raug ntes tau raws sijhawm. Cov kab no tom qab ntawd ua ke hauv lub sijhawm tiag tiag lossis ntawm software los tsim cov duab 2D tag nrho.

Cov khoom tseem ceeb muaj xws li:

● 1-Dimensional sensor: Feem ntau ib kab ntawm pixels.
● Kev tswj cov lus tsa suab: Lub conveyor lossis rotating mechanism ua kom muaj kev txav mus los.
● Teeb pom kev zoo: Feem ntau kab lossis coaxial teeb pom kev zoo rau kev teeb pom kev zoo ib yam.

Vim tias cov duab tau tsim los ntawm kab, synchronization yog qhov tseem ceeb. Yog tias cov khoom txav tsis sib xws lossis lub sijhawm raug kaw, cov duab distortion tuaj yeem tshwm sim.
