Daim ntawv thov ntawm Polarization Microscope thiab Polarization hauv Lub Neej Txhua Hnub
Polarization txoj cai
Hauv cov ntsiab lus yooj yim tshaj plaws, lub teeb ntuj yog transverse nthwv dej, thiab kev co kev taw qhia yog nyob rau hauv tag nrho cov lus qhia. Lub grating yog muab tso rau pem hauv ntej ntawm lub teeb, uas tsuas yog tso cai rau lub teeb vibrating nyob rau hauv ib qho kev taw qhia kom dhau mus. Yog li ntawd, lub teeb dhau los ntawm grating yog polarized teeb.
Polarizing microscope yog ib hom kab mob uas siv los kawm cov ntaub ntawv pob tshab thiab opaque anisotropic. Cov tshuaj nrog birefringence tuaj yeem pom meej meej nyob rau hauv lub tshuab ntsuas polarizing. Tau kawg, cov tshuaj no kuj tuaj yeem raug soj ntsuam siv staining, tab sis qee qhov ua tsis tau thiab yuav tsum tau soj ntsuam siv lub tshuab ntsuas polarizing. Polarization microscope yog ib qho cuab yeej tseem ceeb rau kev kawm thiab txheeb xyuas cov khoom nrog birefringence siv cov yam ntxwv ntawm lub teeb. Nws tuaj yeem siv los ntawm cov neeg siv rau kev soj ntsuam ib leeg polarization, kev soj ntsuam orthogonal polarization, thiab kev soj ntsuam lub teeb cone.
Daim ntawv thov teb:
Geological thiab mineral tsom xam: tsom xam ntawm cov zaub mov thiab muaju.
Kev ua liaj ua teb: Hauv cov kab mob muaj sia, cov txheej txheem fibrin sib txawv pom muaj qhov tseem ceeb anisotropy, thiab cov ncauj lus kom ntxaws txog cov txheej txheem molecular hauv cov fibers tuaj yeem tau txais los ntawm kev siv lub tshuab ntsuas polarizing. Xws li collagen, spindle thaum lub sij hawm cell faib, thiab lwm yam.
Kev txheeb xyuas ntawm ntau yam khoom siv roj ntsha thiab tsis muaj roj ntsha, xws li kev txheeb xyuas cov hmoov txhuv nplej siab, kev txheeb xyuas cov tshuaj muaj pes tsawg leeg, fiber ntau, kua siv lead ua kua, DNA siv lead ua, thiab lwm yam.
Kev tshuaj xyuas kev kho mob: xws li pob zeb, uric acid crystal test, mob caj dab, thiab lwm yam.
Daim ntawv thov ntawm Polarization - Automotive teeb pom kev zoo
Thaum lub tsheb ntsib lub tsheb ntawm txoj kev thaum hmo ntuj, txhawm rau kom tsis txhob pom lub teeb ntawm lub taub hau ntawm ob sab, tus neeg tsav tsheb tig tawm lub teeb taub hau thiab tsuas yog tig rau lub teeb me me, ua kom ceev ceev kom tsis txhob muaj xwm txheej. Yog hais tias lub qhov rais pem hauv ntej ntawm tus tsav tsheb cab thiab lub iav npog ntawm lub teeb lub tsheb yog ob qho tib si nruab nrog polarizers, thiab lawv cov kev taw qhia polarization tau teev tseg rau tib qho kev taw qhia thiab ntawm 45 degree kaum sab xis mus rau kab rov tav, ces tus neeg tsav tsheb tuaj yeem tsuas pom lub teeb tawm los ntawm lawv tus kheej lub tsheb teeb los ntawm lub qhov rais pem hauv ntej, thiab tsis tuaj yeem pom lub teeb ntawm lub teeb pom kev ntawm lub tsheb. Yog li ntawd, thaum tsav tsheb thaum hmo ntuj, tsis txhob tua lub teeb lossis ua kom qeeb kom * * tsav tsheb.
Daim ntawv thov ntawm Polarization - Stereoscopic Cinema
Thaum tua cov yeeb yaj kiab stereoscopic, siv ob lub koob yees duab, thiab lawv cov lo ntsiab muag sib npaug rau ob lub qhov muag tib neeg. Lawv ib txhij ntes ob portraits ntawm tib yam khoom, thiab thaum lub sij hawm projection, ob qho tib si portraits ib txhij projected ntawm qhov screen. Yog tias peb sim ua kom ib lub qhov muag ntawm cov neeg tuaj saib tsuas yog pom ib qho ntawm cov duab, peb tuaj yeem muab cov neeg tuaj saib peb lub ntsej muag. Vim li no, thaum lub sij hawm projection, ob lub projectors tso ib lub polarizer rau txhua lub projector lens, nrog rau cov lus qhia polarization ntawm ob lub polarizers perpendicular rau ib leeg. Cov neeg tuaj saib hnav tsom iav ua los ntawm cov polarizers, thiab cov kev taw qhia polarization ntawm lub polarizer nyob rau sab laug qhov muag yog tib yam li ntawm sab laug projector. Lub polarization kev taw qhia ntawm polarizer nyob rau hauv lub qhov muag sab xis yog tib yam li nyob rau hauv txoj cai projector, thiaj li hais tias ob lub dluab ntawm qhov screen yog pom los ntawm ob lub qhov muag cais, ib tug peb-dimensional duab yog tsim nyob rau hauv tib neeg lub siab.
Polarizing microscope
Polarizing microscope yog ib hom kev tsom xam siv los kawm txog cov ntaub ntawv pob tshab thiab opaque anisotropic, thiab muaj cov ntawv thov tseem ceeb hauv kev tshawb fawb thiab engineering majors xws li geology. Txhua yam khoom siv nrog birefringence tuaj yeem paub meej meej nyob rau hauv lub tshuab ntsuas polarizing, thiab lub tshuab tsom xam polarizing yog ib qho cuab yeej tseem ceeb rau kev kawm thiab txheeb xyuas cov khoom nrog birefringence siv cov yam ntxwv ntawm lub teeb.
