Covlaser beam collimatoryog ib qho khoom siv kho qhov muag, uas feem ntau yog siv los kho thiab raug qhov chaw ntawm lub nqaj.
Nws txoj haujlwm ua haujlwm yog ua raws li kev xav thiab Snell txoj cai ntawm lub teeb.
Lub collimator feem ntau yog tsim los ntawm ob qho tib si ntawm cov iav nrog pob tshab optical nruab nrab sandwiched ntawm lawv. Qhov nruab nrab hauv nruab nrab tuaj yeem yog huab cua, dej, lossis cov kua pob tshab. Qhov chaw ntawm ob lub iav panels yog coated nrog cov hlau zoo heev, feem ntau yog nyiaj thiab txhuas.
Thaum lub teeb beam vertically tua mus rau hauv daim iav collimating, vim Snell txoj cai ntawm lub teeb, lub teeb beam yuav txuas ntxiv mus raws txoj kev mus. Txawm li cas los xij, thaum lub teeb nkag mus rau hauv lub collimator ntawm ib lub kaum ntse ntse, lub nqaj yuav raug cuam tshuam vim yog txoj cai ntawm lub teeb pom kev. Cov kev taw qhia ntawm lub teeb pom kev yog sib npaug rau cov kev taw qhia ntawm qhov teeb meem teeb meem, tab sis opposite nyob rau hauv orientation.
Reflective thiab transmissive collimators yog siv nyob rau hauv beam kis tau tus mob los tuav lub collimation ntawm lub beam ntawm lub laser resonator thiab lub focusing optical keeb. Reflective collimators feem ntau siv tooj liab tag nrho-reflection iav, thaum transmissive collimators siv zinc selenide lo ntsiab muag.
Lub collimator tseem hu ua beam, uas yog cov cuab yeej kho qhov muag siab rau kev ntsuas lub kaum ntse ntse. Nws yog ib qho cuab yeej ntsia rau pem hauv ntej ntawm lub qhov rais tso zis ntawm "tube", uas nws lub luag haujlwm tseem ceeb yog los tswj cov irradiation teb ntawm X-ray tube tso zis kab, kom txo qis qhov projection ntau thiab tsis txhob noj cov tshuaj tsis tsim nyog thaum ua tau raws li cov cai ntawm X. -ray duab thiab kuaj mob; Thiab tuaj yeem nqus tau qee cov kab hluav taws xob tawg, txhim kho qhov pom tseeb ntawm qhov cuam tshuam.
