Polarization microscope thiab kev siv polarization hauv lub neej txhua hnub
Feem ntau hais lus, lub teeb ntuj yog shear yoj, thiab kev co kev taw qhia yog nyob rau hauv tag nrho cov lus qhia. Muab lub grating rau pem hauv ntej ntawm lub teeb, thiab qhov grating no tsuas yog tso cai rau lub teeb uas vibrates nyob rau hauv ib qho kev taw qhia kom dhau mus, ces lub teeb uas hla lub grating yog polarized lub teeb.
Polarizing microscope yog ib hom kev tsom xam 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 pom los ntawm kev dyeing, tab sis qee qhov ua tsis tau, thiab yuav tsum siv lub tshuab tsom iav polarizing. Polarizing microscope yog ib qho cuab yeej tseem ceeb rau kev kawm thiab txheeb xyuas cov tshuaj birefringent los ntawm kev siv cov yam ntxwv ntawm lub teeb, uas tuaj yeem siv rau cov neeg siv los soj ntsuam ib qho polarization, orthogonal polarization thiab cone teeb.
Daim ntawv thov teb:
Geology thiab mineral tsom xam: xws li kev tsom xam ntawm cov zaub mov thiab muaju.
Biological teb: nyob rau hauv cov kab mob, cov qauv fibrin sib txawv qhia pom tseeb anisotropy, thiab cov ntsiab lus ntawm molecular kev npaj hauv cov fibers tuaj yeem tau los ntawm polarizing microscope. Xws li collagen, spinning txhob lo lo ntxhuav thaum lub sij hawm faib cell, thiab lwm yam.
Kev txheeb xyuas ntawm ntau yam khoom siv lom neeg thiab tsis yog lom: xws li kev txheeb xyuas cov khoom siv 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 suav suav, kuaj pom uric acid crystal, mob caj dab, thiab lwm yam.
Daim ntawv thov ntawm lub teeb polarized-automobile teeb
Thaum lub tsheb khiav ntawm txoj kev loj thaum hmo ntuj thiab ntsib lub tsheb sib txawv, txhawm rau kom tsis txhob pom lub teeb ntawm lub taub hau ntawm ob sab, cov neeg tsav tsheb tua lub teeb taws thiab tsuas yog tig lub teeb me me kom qeeb qeeb kom tsis txhob muaj xwm txheej. Piv txwv li, ob qho tib si pem hauv ntej lub qhov rais iav ntawm lub tsheb tavxij thiab lub iav npog ntawm lub teeb taub hau yog nruab nrog cov polarizers, thiab nws tau teev tseg tias lawv cov lus qhia polarization yog tag nrho raws tib qho kev taw qhia thiab ua lub kaum sab xis ntawm 45 degrees nrog lub dav hlau kab rov tav. Tom qab ntawd, tus neeg tsav tsheb tsuas tuaj yeem pom lub teeb ntawm nws tus kheej lub teeb taub hau los ntawm lub qhov rais pem hauv ntej, tab sis tsis yog lub teeb los ntawm cov teeb taws rov qab. Nyob rau hauv txoj kev no, thaum lub tsheb tsav tsheb thaum hmo ntuj, tsis tas yuav tsum tua lub teeb lossis qeeb, uas tuaj yeem ua kom lub * * tsav tsheb.
Daim ntawv thov ntawm Polarization-Stereo Zaj duab xis
Thaum thaij duab peb sab, siv ob lub koob yees duab. Lub lo ntsiab muag ntawm ob lub koob yees duab yog sib npaug rau ob lub qhov muag ntawm tus neeg. Lawv coj ob portraits ntawm tib yam khoom tib lub sij hawm, thiab ob portraits yog reflected nyob rau hauv lub screen tib lub sij hawm. Yog tias koj sim ua kom ib lub qhov muag ntawm cov neeg tuaj saib pom tsuas yog ib qho ntawm cov duab, koj tuaj yeem muab cov neeg tuaj saib peb qhov kev xav. Yog li ntawd, thaum lub sij hawm kev tshuaj ntsuam, ib tug polarizer yog muab tso rau ntawm lub lens ntawm txhua tus neeg uas ua ntawv ntawm ob tug players, thiab cov lus qhia polarization ntawm ob lub polarizers yog perpendicular rau ib leeg. Cov neeg tuaj saib hnav tsom iav ua los ntawm cov polarizers, thiab cov kev taw qhia polarization ntawm sab laug-qhov muag polarizer yog tib yam li cov neeg uas ua ntawv sab laug thiab cov kev taw qhia polarization ntawm sab xis-qhov muag polarizer yog tib yam li cov neeg uas ua ntawv sab xis. .
