Ua ib qho thev naus laus zis tshuaj xyuas pom, thev naus laus zis ntsuas duab yuav tsum paub txog kev ntsuas ntau. Kev ntsuas qhov tseeb yeej ib txwm yog qhov ntsuas tseem ceeb uas cov thev naus laus zis no ua. Cov txheej txheem ntsuas duab feem ntau siv cov khoom siv sensor duab xws li CCDs kom tau txais cov ntaub ntawv duab, hloov lawv mus rau hauv cov cim digital thiab sau lawv rau hauv lub khoos phis tawj, thiab tom qab ntawd siv cov thev naus laus zis ua cov duab los ua cov cim digital kom tau txais ntau yam duab xav tau. Kev suav qhov loj me, cov duab thiab qhov yuam kev ntawm qhov chaw yog ua tiav los ntawm kev siv cov txheej txheem calibration los hloov cov ntaub ntawv loj me ntawm daim duab hauv lub kaw lus sib koom ua ke rau cov ntaub ntawv loj me tiag tiag.
Nyob rau xyoo tas los no, vim yog kev txhim kho sai ntawm kev tsim khoom lag luam thiab kev txhim kho ntawm cov thev naus laus zis ua tiav, ntau yam khoom ntawm ob qhov loj heev, uas yog qhov loj thiab qhov me, tau tshwm sim. Piv txwv li, ntsuas qhov ntev sab nraud ntawm lub dav hlau, ntsuas cov khoom tseem ceeb ntawm cov tshuab loj, ntsuas EMU. Kev ntsuas qhov ntev tseem ceeb ntawm cov khoom me me Qhov sib txawv ntawm kev ua kom me me ntawm ntau yam khoom siv, ntsuas qhov ntev tseem ceeb hauv microelectronics thiab biotechnology, thiab lwm yam, txhua yam coj cov haujlwm tshiab los sim thev naus laus zis. Kev ntsuas duab thev naus laus zis muaj ntau qhov ntsuas dav dua. Nws nyuaj heev rau siv cov kev ntsuas tshuab ib txwm muaj ntawm cov nplai loj thiab me. Kev ntsuas duab thev naus laus zis tuaj yeem tsim qee qhov feem ntawm cov khoom ntsuas raws li qhov yuav tsum tau ua kom raug. Zoom tawm lossis zoom rau hauv kom ua tiav cov haujlwm ntsuas tsis ua tau nrog kev ntsuas tshuab. Yog li ntawd, txawm tias nws yog kev ntsuas loj lossis kev ntsuas me me, lub luag haujlwm tseem ceeb ntawm kev ntsuas duab thev naus laus zis yog qhov pom tseeb.
Feem ntau, peb xa mus rau cov khoom uas muaj qhov loj me ntawm 0.1 hli txog 10 hli ua cov khoom me me, thiab cov khoom no tau txhais thoob ntiaj teb ua cov khoom mesoscale. Qhov yuav tsum tau ua kom raug ntawm cov khoom no yog qhov siab heev, feem ntau ntawm qib micron, thiab cov qauv yog qhov nyuaj, thiab cov txheej txheem nrhiav pom ib txwm nyuaj rau ua kom tau raws li qhov xav tau kev ntsuas. Cov txheej txheem ntsuas duab tau dhau los ua ib txoj hauv kev dav dav hauv kev ntsuas cov khoom me me. Ua ntej, peb yuav tsum thaij duab ntawm cov khoom uas raug sim (lossis cov yam ntxwv tseem ceeb ntawm cov khoom uas raug sim) los ntawm lub lens optical nrog qhov loj txaus ntawm lub sensor duab sib phim. Tau txais ib daim duab uas muaj cov ntaub ntawv ntawm lub hom phiaj ntsuas uas ua tau raws li qhov yuav tsum tau ua, thiab sau cov duab rau hauv lub khoos phis tawj los ntawm daim npav tau txais duab, thiab tom qab ntawd ua cov txheej txheem ua duab thiab xam los ntawm lub khoos phis tawj kom tau txais cov txiaj ntsig ntsuas.
Cov thev naus laus zis ntsuas duab hauv thaj chaw ntawm cov khoom me me feem ntau muaj cov qauv kev loj hlob hauv qab no: 1. Txhim kho qhov tseeb ntawm kev ntsuas. Nrog rau kev txhim kho tas mus li ntawm qib kev lag luam, qhov yuav tsum tau ua kom raug rau cov khoom me me yuav raug txhim kho ntxiv, yog li txhim kho qhov tseeb ntawm kev ntsuas qhov tseeb ntawm cov thev naus laus zis ntsuas duab. Tib lub sijhawm, nrog rau kev txhim kho sai ntawm cov khoom siv sensor duab, cov khoom siv daws teeb meem siab kuj tsim cov xwm txheej rau kev txhim kho qhov tseeb ntawm lub kaw lus. Tsis tas li ntawd, kev tshawb fawb ntxiv txog cov thev naus laus zis sub-pixel thiab cov thev naus laus zis super-resolution kuj tseem yuav muab kev txhawb nqa kev siv tshuab rau kev txhim kho qhov tseeb ntawm lub kaw lus.
2. Txhim kho kev ntsuas kom zoo. Kev siv cov khoom me me hauv kev lag luam tab tom loj hlob ntawm qib geometric, cov haujlwm ntsuas hnyav ntawm 100% kev ntsuas hauv kab thiab cov qauv tsim khoom xav tau kev ntsuas kom zoo. Nrog kev txhim kho ntawm cov peev xwm kho vajtse xws li khoos phis tawj thiab kev ua kom zoo dua ntawm cov algorithms ua duab, kev ua haujlwm ntawm cov cuab yeej ntsuas duab yuav raug txhim kho.
3. Paub txog kev hloov pauv ntawm cov khoom me me los ntawm hom ntsuas qhov taw tes mus rau hom ntsuas tag nrho. Cov cuab yeej ntsuas duab uas twb muaj lawm tsuas yog txwv los ntawm qhov tseeb ntawm kev ntsuas, thiab feem ntau yog duab thaj chaw tseem ceeb hauv cov khoom me me, yog li ntawd thiaj li paub txog kev ntsuas ntawm qhov tseem ceeb, thiab nws nyuaj rau ntsuas tag nrho cov duab lossis tag nrho cov ntsiab lus.
Nrog kev txhim kho ntawm qhov ntsuas qhov tseeb, tau txais daim duab tiav ntawm qhov thiab ua tiav qhov kev ntsuas siab ntawm qhov yuam kev ntawm tag nrho cov duab yuav raug siv rau hauv ntau dua thiab ntau qhov chaw.
Hauv ntej, hauv kev ntsuas me me, kev ua haujlwm siab ntawm cov thev naus laus zis ntsuas duab siab yuav dhau los ua qhov tseem ceeb ntawm kev txhim kho thev naus laus zis ntsuas qhov tseeb. Yog li ntawd, cov khoom siv kho vajtse tau txais cov kev xav tau siab dua rau qhov zoo ntawm cov duab, qhov chaw ntawm ntug duab, kev ntsuas qhov system, thiab lwm yam, thiab muaj kev cia siab dav dav thiab qhov tseem ceeb ntawm kev tshawb fawb. Yog li ntawd, cov thev naus laus zis no tau dhau los ua qhov chaw tshawb fawb hauv tsev thiab txawv teb chaws, thiab tau dhau los ua ib qho ntawm cov ntawv thov tseem ceeb tshaj plaws hauv kev siv tshuab tshuaj xyuas pom.
