Qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib kis yog qhov sib txawv ntawm cov gratings tuaj yeem cais lub teeb polychromatic rau hauv nws cov qauv wavelengths, whereas transmission gratings yog ib hom diffraction gratings uas muaj qhov sib txawv ntawm lub teeb nyob rau hauv ntau lub ces kaum los muab cov qauv diffraction.
Muaj plaub yam loj ntawm diffraction gratings. Cov no muaj xws li txiav gratings, holographic gratings, kis gratings, thiab reflection gratings. Yog li ntawd, kev sib kis gratings yog ib hom diffraction gratings.
Diffraction Grating yog dab tsi?
A diffraction grating yog ib qho khoom siv kho qhov muag uas muaj cov qauv ua ntu zus uas tuaj yeem cuam tshuam lub teeb rau hauv ob peb kab teeb uas nyiam mus rau ntau qhov kev taw qhia. Cov kev taw qhia sib txawv no yog txuam nrog qhov sib txawv diffraction. Qhov system grating no tuaj yeem ua rau muaj xim nyob rau hauv daim ntawv ntawm cov qauv xim. Diffraction angles yog nyob ntawm qhov xwm txheej yoj lub kaum sab xis, qhov chaw nruab nrab ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov system grating, thiab wavelength ntawm qhov teeb meem teeb.
Daim duab 01: Lub Teeb Teeb Teeb uas tau pom los ntawm Transmissive Diffraction Grating
Lub grating system tuaj yeem ua raws li cov khoom tawg. Yog li, peb tuaj yeem siv nws ua monochromator thiab ua spectrometer. Txawm li cas los xij, muaj qee qhov kev siv tau zoo ib yam, uas suav nrog optical encoders rau siab precision motion control and wave-front measurement.
Hauv cov ntawv thov ib txwm, lub ntsej muag pom muaj cov ridges lossis cov lus txiav txim rau ntawm qhov chaw. Txawm li cas los xij, lub transmissive grating muaj transmissive los yog hollow slits ntawm qhov chaw. Hom grating system no tuaj yeem hloov kho qhov amplitude ntawm qhov xwm txheej nthwv dej los tsim cov qauv sib txawv. Tsis tas li ntawd, muaj cov gratings uas tuaj yeem hloov kho cov theem ntawm qhov xwm txheej tsis zoo piv rau qhov amplitude. Ntxiv mus, peb tuaj yeem tsim cov gratings siv holography.
Feem ntau, qhov sib txawv grating ua cov xim zaj sawv thaum pom qhov dav dav ntawm lub teeb ci. Piv txwv li, cov xim zoo li zaj sawv tshwm hauv CDs thiab DVDs. Feem ntau, lub diffraction grating muaj cov kab sib txuas. Tab sis nyob rau hauv ib lub CD, muaj cov kab kauv uas zoo sib nrug ntawm cov ntaub ntawv lem.
Dab tsi yog Transmission Grating?
Kev xa tawm gratings yog hom diffraction gratings uas tuaj yeem siv hauv kev sib kis. Peb tuaj yeem sib tham txog kev sib kis gratings hauv kev tawm tsam rau kev cuam tshuam cov kab ke. Reflection gratings qhia txog txhua qhov teeb meem teeb meem es tsis yog nqus los yog tawg lub teeb. Txawm li cas los xij, kev sib kis gratings tuaj yeem cuam tshuam lub teeb ntawm qhov sib txawv.
Daim duab 02: Kev xa tawm Gratings
Ib kis tau tus mob grating yuav tsum tau ua tib yam slits ntawm grating nto. Cov no yog hu ua transmissive lossis hollow slits. Hom grating no tuaj yeem hloov kho qhov amplitude ntawm qhov xwm txheej nthwv dej ntawm qhov chaw los tsim cov qauv diffraction. Feem ntau, ob hom loj ntawm diffraction gratings yog reflective gratings thiab transmissive gratings.
Dab tsi yog qhov txawv ntawm Diffraction Grating thiab Transmission Grating?
Kev xa tawm grating yog hom diffraction grating. Qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab kev sib kis grating hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Diffraction Grating vs Transmission Grating
A diffraction grating yog ib qho khoom siv kho qhov muag uas muaj cov qauv ua ntu zus uas tuaj yeem cuam tshuam lub teeb rau hauv ob peb kab teeb uas nyiam mus rau ntau qhov kev taw qhia. Meanwhile, kis gratings yog ib hom diffraction gratings uas yuav siv tau nyob rau hauv kev sib kis. Qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv yog qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv.
