Lub Koob Yees Duab Hmo Ntuj

Optoelectronic Image Enhancement
Yuav luag txhua lub koob yees duab classic, binoculars, monoculars, thiab lub koob yees duab pom kev hmo ntuj yog ua raws li txoj kev txhim kho optoelectronic. Nws siv ib qho tshwj xeeb duab intensifier thiab ob peb optical lo ntsiab muag. Lub hauv paus ntsiab lus kev khiav hauj lwm ntawm xws li lub koob yees duab yog conventionally muab faib ua tsib theem tseem ceeb. Hauv thawj zaug, lub lens optics sau tag nrho cov teeb pom kev zoo. Tom qab ntawd nws dhau los ntawm cov lo ntsiab muag mus rau cov duab intensifier. Lub tom kawg yog ib qho cuab yeej uas photons hloov mus rau hauv electrons thiab amplified ntau zaus siv lub phaj microchannel. Nyob rau theem tom ntej hloov dua siab tshiab, lub amplified electrons poob rau ntawm ib qho screen nrog phosphor txheej. Qhov tshwm sim yog cov duab uas ua kom ci dua thiab sib txawv ntau zaus dua li qhov qub. Daim duab tso tawm kom pom, thiab tus neeg siv pom dab tsi tshwm sim hauv qhov tsaus ntuj.

Cov koob yees duab siv cov duab kho qhov muag-kho cov duab hluav taws xob tuaj yeem tiv taus lawv cov dej num ntawm txhua theem teeb. Qhov loj tshaj plaws yog tias thaum hmo ntuj qhib, qee qhov chaw ntawm lub teeb hluav taws xob muaj. Qhov no tuaj yeem yog cov khoom ci ntsa iab saum ntuj (hnub qub pawg, comets, Lub hli, thiab lwm yam), lub teeb ntawm txoj kev lossis teeb pom kev kub hnyiab qhov chaw deb ntawm koj, thiab ntau ntxiv. Cov duab tsim tawm yuav tsis muaj ntau xim (feem ntau ntsuab, tab sis qee zaum muaj cov ntxaij lim dej ntawm lwm cov xim), tso cai rau koj pom cov khoom kom ntxaws. Cov qauv niaj hnub no tsis muaj ntau yam tsis xws luag uas tiv thaiv lub qhov muag kom tsis txhob pom cov duab.

Digital Image Enhancement
Tsis zoo li hom qauv ntawm lub koob yees duab pom kev hmo ntuj, cov digital siv lub hauv paus ntsiab lus ncaj qha ntawm kev txhim kho duab. Qhov no yog qhov ua tau zoo tshaj plaws nyob rau hauv qhov tsaus ntuj thiab yuav luag ib txwm lav lub ntsiab lus siab, yog li kev txhim kho digital yog siv nyob rau hauv yuav luag txhua yam khoom siv niaj hnub no.

Tag nrho cov txheej txheem pib nrog lub lens. Nws sau cov teeb pom kev zoo thiab xa mus rau lub converter tshwj xeeb. Lub tom kawg muaj nyob rau hauv nws tsim CMOS sensor uas hloov cov ntaub ntawv tau txais mus rau hauv lub teeb liab digital. Qhov no tsuas yog ob peb feem ntawm ib ob tab sis yog qhov tseem ceeb tshaj plaws hauv kev tsim cov txiaj ntsig kawg. Tom qab hloov dua siab tshiab, cov duab tau ua tiav los ntawm lub tshuab hluav taws xob. Cov theem no tso cai rau koj kom nce sharpness thiab brightness thiab tshem tawm ntau yam tsis xws luag. Cov duab tsim raug xa mus rau cov zaub uas tus neeg siv pom nws.

Cov txheej txheem digital amplification ua tau zoo dua li optoelectronic ib qho. Cov duab generated yuav luag ib txwm muaj cov ntsiab lus zoo thiab yog cov ntaub ntawv raws li qhov ua tau. Tsis tas li ntawd, cov txheej txheem digital amplification yog nrawm dua, tshem tawm cov kev ncua lossis kev hais lus thaum saib cov xwm txheej ceev ceev. Lwm qhov zoo dua ntawm kev nthuav dav digital yog lub peev xwm los siv kev ua haujlwm ntxiv. Nws tso cai rau koj hloov lub koob yees duab kev ua haujlwm rau tus kheej xav tau ntawm txhua tus neeg siv.

Infrared Hmo Ntuj Pom Kev
Cov koob yees duab kev ruaj ntseg siv infrared hmo ntuj pom kev, uas tso siab rau IR teeb ua haujlwm. Nws yog qhov pom tsis pom ntawm qhov muag liab qab, yog li nws tsis unmask tus neeg siv thiab tsis cuam tshuam nrog lwm tus neeg ua ntau yam kev ua ib txhij. Txhawm rau nkag siab qhov no zoo dua, xav txog koj cov chaw taws teeb TV tam sim no. Nws muaj lub teeb liab LED nyob rau pem hauv ntej ntawm lub cuab yeej thiab xa cov teeb liab infrared rau koj lub TV. Koj tsis tuaj yeem pom cov kab no xa mus rau TV hauv lub dav hlau infrared focal. Tib yam tuaj yeem hais rau IR illuminators lossis teeb nyem. Cov cuab yeej no feem ntau yog ntsia rau ntawm lub koob yees duab thiab tawm lub teeb infrared uas tso cai rau koj los ntes cov duab / yeeb yaj kiab thiab saib lawv hauv qhov tsaus ntuj. Cov neeg tsim khoom tau pib muab cov koob yees duab kev ruaj ntseg niaj hnub no nrog cov teeb pom kev zoo infrared, muab kev pom kev hmo ntuj nyob rau hauv cov teeb pom kev zoo. Tsis tas li ntawd, lawv muaj txiaj ntsig zoo hauv kev tsaus ntuj, uas ua rau lawv tsis muaj peev xwm pab tau rau cov neeg sawv cev ntawm ntau txoj haujlwm.

Feem ntau cov koob yees duab kev ruaj ntseg tso tawm hnub no nrog lub peev xwm pom kev hmo ntuj kuj tseem tuaj nrog IR txiav lim. Nws yog lub tshuab kaw lus nruab nrab ntawm lub koob yees duab lens thiab cov duab sensor. Cov lim dej no tuaj yeem pom lub teeb pom kev nyob ib puag ncig (natural lossis khoom siv dag zog) thiab siv IR-thaiv cov lim dej txhua hnub kom khaws cov duab thiab pom tseeb ntawm nruab hnub. Lub teeb sensor ntawm lub koob yees duab soj ntsuam tswj lub IR txiav lim. Thaum tsaus ntuj, nws tsuas yog xa cov teeb liab tshem tawm mus rau IR txiav lim kom ntau lub teeb tuaj yeem ncav cuag lub koob yees duab kev ruaj ntseg cov duab sensor. Qhov no tso cai rau ntau lub teeb los ntawm, suav nrog IR teeb los ntawm lub koob yees duab. Feem ntau, txhua lub koob yees duab digital infrared tso saib cov duab dub-thiab-dawb nyob rau hauv hmo ntuj pom kev zoo dua li cov xim ntsuab uas nrov los ntawm cov xim phosphor ntawm analog hmo pom kev.

Low-Light Night Vision
Lub teeb pom kev hmo ntuj qis yog ua raws li kev siv tshuab amplification uas muab cov duab pom xim hmo ntuj nyob rau hauv cov teeb pom kev tsawg heev. Thaum lub teeb ambient ntog rau ntawm lub phaj photocathode, electrons raug tso tawm los ntawm lub tshuab nqus tsev vacuum uas tsoo lub microchannel phaj, uas ua rau cov duab tshwm ntawm qhov screen tib yam li qhov teeb meem teeb meem ntawm photocathode thiab ntawm qhov zaus uas tib neeg lub qhov muag. pom tau. Feem ntau cov tshuab analog uas twb muaj lawm niaj hnub no tuaj yeem tso saib cov duab ntsuab lossis dub thiab dawb. Cov kev xaiv tshwj xeeb yog nyob ntawm hom duab intensifier siv (ntsuab los yog dawb phosphorus). Vim tias cov cuab yeej no siv qhov muag pom ntau dua li lub tshuab hluav taws xob digital, qhov pom tseeb thiab kev daws teeb meem ntawm cov khoom siv analog feem ntau yog siab dua li cov khoom siv digital. Qhov txawv ntawm qhov ntsuas no tsis tseem ceeb, tab sis nws tseem pom. Qhov no yuav yog qhov tseem ceeb tshwj xeeb tshaj yog thaum koj xav pom cov ntsiab lus me me ntawm cov khoom hauv qhov tsaus ntuj.

Cov neeg uas siv cov koob yees duab zoo li no yuav tsum nco ntsoov ib qho kev nthuav dav tseem ceeb. Vim lub raj lub photosensitivity, muaj kev pheej hmoo ntawm kev puas tsuaj los ntawm lub teeb ci. Hauv qhov no, nws yog ib qho tsim nyog yuav tsum siv cov lim dej tshwj xeeb lossis ua kom ceev faj ntxiv. Txwv tsis pub, lub teeb los ntawm lub hnub, cov teeb pom kev nyob ze, lub teeb lub tsheb thiab lwm yam khoom yuav ua rau lub raj puas thiab ua rau nws tsis tuaj yeem siv lub koob yees duab pom kev hmo ntuj ntxiv.
