Nyob rau lub caij nyoog ntawm kev siv tshuab siab heev, cov txheej txheem kev lag luam tau ua haujlwm tau zoo dua thiab meej dua. Ib qho kev nce qib zoo li no yog kev siv cov neeg hlau laser vuam hauv kev tsim khoom. Cov neeg hlau no muab cov vuam zoo thiab meej, ua kom ntseeg tau tias cov khoom kawg ruaj khov thiab ntseeg tau. Txawm li cas los xij, txhawm rau kom ntseeg tau tias qhov zoo vuam sib xws thiab txhim khu kev qha, ntau txoj hauv kev yuav tsum tau siv los xyuas qhov zoo ntawm cov neeg hlau laser vuam. Hauv tsab xov xwm no, peb yuav tshawb nrhiav ntau txoj hauv kev los xyuas qhov zoo ntawm cov neeg hlau laser vuam.
Ua ntej pib qhia cov txheej txheem no, nws yog ib qho tseem ceeb kom nkag siab tias cov kev ntsuas vuam ntawmlaser vuam neeg hlauyuav tsum tau hloov kho raws li qhov zoo ntawm kev vuam tiag tiag. Qhov kev hloov kho no ua kom ntseeg tau tias tus neeg hlau xa cov txiaj ntsig zoo tshaj plaws thaum lub sijhawm vuam ntau. Yuav tsum tau muab tso rau ntawm kev kho thiab kho kom zoo ntawm lub tshuab kom ua tiav qhov zoo ntawm kev vuam xav tau.
Ib qho ntawm cov txheej txheem siv ntau los xyuas qhov zoo ntawm kev vuam ntawm cov neeg hlau laser vuam yog kev kuaj pom qhov tsis zoo ntawm cov duab hluav taws xob. Txoj kev no suav nrog kev siv X- thiab Y-rays los xa cov hluav taws xob los ntawm qhov vuam. Cov qhov tsis zoo uas muaj nyob hauv qhov vuam ces raug tso tawm rau ntawm daim duab hluav taws xob, uas cia tus neeg teb xov tooj txheeb xyuas cov qhov tsis zoo. Los ntawm kev siv txoj kev no, qhov zoo ntawm qhov vuam tuaj yeem soj ntsuam kom zoo kom ntseeg tau tias tsis muaj qhov tsis zoo zais uas tuaj yeem cuam tshuam rau kev ncaj ncees ntawm qhov vuam.
Ntxiv rau kev kuaj pom qhov tsis zoo ntawm cov duab hluav taws xob, lwm txoj hauv kev los xyuas qhov zoo ntawm kev vuamcov neeg hlau laser vuamyog kev kuaj pom qhov tsis zoo ntawm ultrasonic. Txoj kev no siv cov kev co pulsed uas tsim los ntawm kev siv hluav taws xob tam sim ntawd. Tus neeg sawv cev txuas tau siv rau ntawm qhov chaw ntawm qhov vuam kom ua rau cov nthwv dej ultrasonic tsim nyob rau hauv cov hlau. Thaum cov nthwv dej no ntsib qhov tsis zoo, lawv tso tawm cov teeb liab uas tuaj yeem soj ntsuam kom paub txog txhua qhov tsis zoo uas muaj nyob hauv qhov vuam. Txoj kev no ua raws li cov ntsiab cai zoo sib xws rau kev kuaj ultrasound hauv cov tsev kho mob, kom ntseeg tau tias cov txiaj ntsig txhim khu kev qha thiab raug.
Kev tshawb nrhiav qhov tsis zoo ntawm hlau nplaum kuj yog ib txoj hauv kev zoo los xyuas qhov zoo ntawm kev vuamcov neeg hlau laser vuam. Txoj kev no suav nrog kev siv hmoov hlau nplaum rau ntawm qhov chaw vuam. Thaum muaj qhov tsis zoo, cov khoom siv hlau nplaum yuav ua rau muaj qhov xau. Los ntawm kev tshuaj xyuas lub zog hlau nplaum, tus neeg teb xov tooj tuaj yeem txiav txim siab seb puas muaj qhov tsis zoo ntawm qhov vuam. Txoj kev no muaj txiaj ntsig zoo rau kev txheeb xyuas qhov tsis zoo ntawm qhov chaw vuam thiab xyuas kom meej tias qhov zoo ntawm qhov vuam ua tau raws li cov qauv xav tau.
Ntxiv rau peb txoj kev siv feem ntau no, muaj lwm cov txheej txheem uas siv tau los xyuas qhov zoo ntawm kev vuamcov neeg hlau laser vuam. Cov no suav nrog kev tshuaj xyuas pom, kev sim kua nkag mus thiab kev sim eddy tam sim no. Kev tshuaj xyuas pom suav nrog kev tshuaj xyuas kom meej ntawm qhov vuam nrog lub qhov muag liab qab lossis nrog kev pab los ntawm lub cuab yeej magnifying. Kev sim kua nkag mus, ntawm qhov tod tes, siv cov kua nkag mus rau hauv qhov tsis zoo ntawm qhov chaw, ua rau lawv pom hauv qab lub teeb ultraviolet. Kev sim eddy tam sim no siv electromagnetic induction los txheeb xyuas qhov tsis zoo ntawm qhov chaw thiab hauv qab los ntawm kev ntsuas kev hloov pauv ntawm kev coj hluav taws xob.
Tag nrho cov txheej txheem no ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo ntawm cov neeg hlau laser vuam. Los ntawm kev siv cov thev naus laus zis no, cov chaw tsim khoom tuaj yeem txheeb xyuas cov qhov tsis zoo lossis qhov tsis zoo ntawm kev vuam thiab ua cov kauj ruam tsim nyog los kho lawv. Qhov no ua rau cov khoom zoo dua thiab kev txaus siab ntawm cov neeg siv khoom.
Hauv kev xaus, kev kuaj xyuas qhov zoo ntawm kev vuamlaser vuam neeg hlauyog qhov tseem ceeb kom ntseeg tau tias qhov khoom kawg muaj kev ntseeg siab thiab ruaj khov. Ntau txoj kev xws li kev kuaj duab hluav taws xob, ultrasonic thiab magnetic tuaj yeem muab kev nkag siab zoo rau qhov zoo ntawm weld. Cov chaw tsim khoom yuav tsum koom nrog cov txheej txheem no rau hauv lawv cov txheej txheem tswj xyuas kom zoo kom tswj tau cov qauv siab ntawm qhov zoo ntawm weld. Thaum ua li ntawd, lawv tuaj yeem xa cov khoom uas ua tau raws li lossis tshaj qhov kev cia siab ntawm cov neeg siv khoom thiab tsim lub koob npe nrov rau kev ua tau zoo hauv kev lag luam.
