Vim polarizer vs linear polarizer
Polarization yog ib lub tswv yim tseem ceeb uas tau tham txog hauv kev kho qhov muag. Lub voj voog polarization thiab linear polarization yog ob hom polarization. Lub voj voog polarizers thiab linear polarizers yog cov cuab yeej siv los ua kom tiav polarization. Polarization yog siv dav hauv kev sim kho qhov muag, looj tsom iav dub, cov ntxaij lim dej yees duab, tints thiab ntau lwm yam kev siv. Nws yog ib qho tseem ceeb kom muaj kev nkag siab zoo hauv ob qho tib si ncig polarization thiab linear polarization thiaj li ua tau zoo hauv optics. Hauv tsab xov xwm no, peb yuav tham txog dab tsi polarization yog dab tsi, lub voj voog polarization thiab linear polarization yog dab tsi, lawv cov ntsiab lus, qhov zoo sib xws ntawm lub voj voog polarization thiab linear polarization, lawv cov ntawv thov, thiab thaum kawg qhov sib txawv ntawm cov polarizers thiab linear polarizers.
Linear Polarizer yog dab tsi?
Yuav kom nkag siab cov kab polarizer, ib tus yuav tsum xub nkag siab cov kab polarization. Polarization tsuas yog txhais tau tias yog ib hom kev taw qhia ntawm oscillations hauv nthwv dej. Polarization ntawm nthwv dej piav qhia cov kev taw qhia ntawm oscillation ntawm nthwv dej nrog rau kev coj ntawm kev nthuav tawm; Yog li ntawd, tsuas yog transverse nthwv dej tso saib polarization. Lub oscillation ntawm hais nyob rau hauv ib tug longitudinal yoj ib txwm nyob rau hauv cov kev taw qhia ntawm propagation; Yog li ntawd, lawv tsis pom polarization.. Xav txog lub nthwv dej taug kev los ntawm qhov chaw; Yog hais tias lub nthwv dej yog ib tug mechanical yoj, particle yog cuam tshuam los ntawm nthwv dej thiab oscillates. Yog hais tias cov particle oscillates ntawm ib tug taag kab perpendicular rau cov kev taw qhia ntawm propagation, yoj yog hais tias yuav linearly polarized. Muaj ob hom linear polarizers. Ib qho yog qhov nqus polarizer, thiab lwm qhov yog cov nqaj sib cais polarizer. Lub polarizer absorbs lub teeb ntawm txhua qhov kev taw qhia uas tsis yog qhov xav tau polarization. Lub beam splitting polarizer splits qhov xwm txheej rau hauv ob qho tib si perpendicular Cheebtsam thiab tshem tawm ib feem ntawm lub nqaj. Nyob rau hauv qhov kev nkag siab no, lub beam splitting polarizer muab qhov kev siv zog zoo dua li qhov nqus polarizer.
Vim polarizer yog dab tsi?
Zoo polarizer yog ib yam khoom siv kom tau txais lub voj voog polarization. Yuav kom nkag siab txog lub voj voog polarizer, ib tus yuav tsum xub nkag siab txog lub voj voog polarization. Nyob rau hauv voj voog polarization, lub hypothetical particle yog tsiv nyob rau hauv ib lub voj voog perpendicular mus rau cov kev taw qhia ntawm propagation. Muaj ob hom kev ncig polarization. Namely lawv yog clockwise thiab anticlockwise polarization. Cov no tseem hu ua sab laug tes polarization thiab txoj cai tes polarization. Lub voj voog polarization tau txais los ntawm kev xa lub teeb tsis muaj polarized los ntawm cov kab polarizer thiab lub quarter yoj phaj. Lub voj voog polarizers feem ntau yog siv los ua cov ntxaij lim dej yees duab thiab lo ntsiab muag ntawm cov iav stereoscopic (uas feem ntau hu ua 3D tsom iav).
Qhov txawv ntawm Circular Polarizers thiab Linear Polarizers yog dab tsi?
• Linear polarizers yog tsim los ntawm ib qho kev tivthaiv, whereas ncig polarizer xav tau ib tug linear polarizer thiab ib lub quarter yoj phaj.
• Linear polarizers yog siv nyob rau hauv looj tsom iav dub (polaroid tsom iav) thiab tints. Lub voj voog polarizers yog siv hauv cov duab thaij duab, 3D tsom iav thiab lwm yam.
• Muaj ob hom kab polarizers nyob ntawm cov polarization lawv tsim, tab sis tsuas muaj ib hom kab polarizer nyob ntawm cov polarization tsim.
