Qhia txog Txoj Cai thiab Kev Siv Tshuab ntawm Illuminometer
Ntau tus neeg yuav tsis tau nkag siab tiag tiag lub illuminometer, thiab tej zaum yuav tsis paub nws txoj cai lossis kev siv tshuab. Cia wb mus saib ua ke:
Illuminometer yog lub tshuab luam ntawv tsis siv neeg fiber ntau optic ntsuas qhov siv ntawm cov khoom tsim thiab ntuj tsim. Nws daws qhov teeb meem ntawm kev ntsuas tsis tu ncua ntawm lub teeb siv thiab tsis siv neeg kaw. Nws yog tsim los ntawm photodetector, ib qho kev hloov pauv tsis siv neeg lub voj voog, lub kaw lus nkhaus, lub tshuab luam ntawv digital, thiab cov khoom siv tam sim no digital. Lub nkhaus kaw cov cuab yeej siv lub fiber optic frictionless kaw txoj kev, thiab lub photodetector yog tsim los ntawm ib tug lim thiab ib tug xiav silicon photocell, thiaj li hais tias cov pom spectrum teb nkhaus conforms rau tib neeg pom spectrum nkhaus tau teev tseg los ntawm International Commission on Illumination (CIE) .
Pocket electronic illuminometer belongs rau lub teb ntawm illuminance ntsuas tshuab, haum rau ntsuas illuminance nyob rau hauv kev ua liaj ua teb ntau lawm, lub neej txhua hnub, thiab sab nraum zoov mus txawv tebchaws. Nws siv cov photosensitive resistor li photoelectric converter ntaus ntawv, uas muaj ib tug DC fais fab mov thiab txuas txuas nyob rau hauv series nrog ib tug voltage converter Circuit Court, hloov, photosensitive resistor, kuaj Circuit Court, A / D converter, decoder, zaub tsav tsheb, thiab tso saib ntawm qhov tso zis kawg ntawm DC fais fab mov. Cov qauv siv hluav taws xob no zam kev siv lub taub hau photometric, thiab DC fais fab mov tsuas yog siv 3V roj teeb. Lub decoder, tso saib tsav tsheb, thiab cov zaub tau muab tso rau ntawm ib daim npav sib xyaw ua ke, ua rau nws yooj yim hauv cov qauv, me me, yooj yim txav, thiab tseem muaj qhov zoo ntawm cov lus teb rhiab. Ib qho ultraviolet hluav taws xob illuminometer belongs rau cov cuab yeej ntsuas qhov muag. Nws cov yam ntxwv yog tias nws muaj ob lub unidirectional cutoff optical filters thiab ob lub photoelectric receivers zoo tib yam los tsim ib tug dual optical path detector. Lub Circuit Court ib feem siv dual amplification, uas tuaj yeem ntsuas qhov ntsuas hluav taws xob ntawm qhov ntsuas qhov xav tau. Lub teeb stray cutoff muaj zog
Lub hauv paus ntsiab lus ntawm kev ntsuas lub illuminometer: Illuminance yog qhov ntom ntom ntawm cov luminous flux tau txais ntawm lub dav hlau illuminated. Illuminometer yog ib qho cuab yeej siv los ntsuas qhov illuminance ntawm lub teeb ci ntsa iab, thiab yog ib qho ntawm cov cuab yeej siv feem ntau hauv kev ntsuas illuminance.
Lub hauv paus ntsiab lus ntawm lub illuminometer: Lub illuminometer muaj lub taub hau photometer (tseem hu ua lub teeb tau txais kev sojntsuam, suav nrog lub receiver, V ( λ) ) Nws muaj ob ntu: lim, cosine corrector, thiab nyeem ntawv.
