Taw qhia yuav ua li cas calibrate cov polarizers ntawm polarizing tsom iav
Hauv kev ua haujlwm, kev co cov kev taw qhia ntawm cov duab sab saud thiab sab hnub poob thiab sab qab teb thiab sab qab teb thiab sab qab teb thiab cov kab rov tav. Qee lub sij hawm tsuas yog ib qho qis dua polarizer yog siv rau kev soj ntsuam, thiab kev co cov kev co ntawm cov qis dua polarizer yuav tsum muaj kev txiav txim siab, yog li cov polarizer yuav tsum ntsuas lub sijhawm ua haujlwm.
1. Nrhiav kom pom ntawm Crosshair hauv Eyepiece
Feem ntau, nws yog ib qho tsim nyog los tshuaj xyuas seb cov kab xev crosshair yog orthogonal thiab zoo ib yam nrog cov kev co ntawm sab sauv thiab qis dua mirarizing tsom iav. Nyob rau tib lub sijhawm, xaiv ib daim biotite nrog cov xov tooj ntawm lub ntsej muag, thiab tom qab ntawd tig mus rau theem crosshahad, thiab tom qab ntawd tig lub ntsej muag los ua kom lub ntsej muag sib txuas mus rau lwm tus ntoo khaub lig. Sau cov nplai naj npawb ntawm theem. Qhov sib txawv ntawm ob qib nyeem yog 90 degree, qhia tias tus ntoo khaub lig yog orthogonal.
2. Kev txiav txim siab thiab kho kho ntawm qhov kev co ntawm daim iav polarizing
Feem ntau, biotite yog siv los tshawb xyuas qhov kev co ntawm polarizing tsom iav, vim tias bientite yog ib qho chaw xa khoom tawg yooj yim. Firstly, nrhiav tau qhov tseeb thiab tuav nws lub ntsej muag, thawb tawm ntawm lub ntsej muag ntawm tus kab mob sab saud, tig mus rau theem sab saud, thiab saib cov xim hloov pauv ntawm biotite. Vim tias bientite nqus cov teeb nyob rau hauv cov kev taw qhia ruaj khov, thaum cov xim botioite nce mus tob, cov kev coj ntawm cleavage seam yog qhov kev co ntawm tus lej qis dua.
3. Kho kev txhim kho ntawm Orthoogonal Polarization ntawm Sab Sauv thiab Qaum Qaum Ntuj
Tom qab sib txawv ntawm cov kev taw qhia ntawm tus lej qis dua, tshem tawm cov yeeb yaj kiab nyias nyias thiab thawb nws mus rau sab saud saib puas yog xim dub lossis hauv lub xeev ntev. Yog tias nws yog xim dub, nws qhia tau tias cov kev co ntawm cov kev taw qhia ntawm cov polarizations sab saud thiab qis dua yog orthogonal rau ib leeg. Txwv tsis pub, tus polarizer yuav tsum ntsuas kom ua rau kev pom kev tsaus ntuj. Thaum tig, cov ntsia hlau ntawm cov polarizer sab saud yuav tsum tau xoob ua ntej, ntsuas kom raug, thiab tom qab ntawd nruj.
