Qhov ceev tshaj plaws hauv peb lub ntiaj teb yog qhov ceev ntawmQhov Chaw Teeb, thiab qhov ceev ntawm lub teeb kuj coj peb ntau yam zais cia. Qhov tseeb, tib neeg tau ua tiav kev kawm txog optics, thiab cov thev naus laus zis uas peb paub tau dhau los ua ntau dua thiab ntau dua. Kev tshawb fawb yog ib hom hwj chim, peb tsuas paub kev tshawb fawb xwb, txhawm rau kom nplua nuj lawv lub neej, cov phooj ywg tuaj yeem ntxiv kuv cov kiv cua, ua ke los kawm txog lub ntiaj teb ntawm kev tshawb fawb txog tej yam nthuav.
Peb paub tias kev kawm txog optics yog ib qho kev tshawb fawb thiab thev naus laus zis nyuaj, xav kom paub txog lub teeb xav tau cov cuab yeej siv siab heev, tib neeg hauv kev kawm txog optics yuav tsum siv zog ntau, yog kom muaj peev xwm kawm ntau yam thev naus laus zis optical. Tsis ntev los no, muaj ib cov lus uas tau ntes kuv lub siab, uas yog, qee cov ntaub ntawv hais txog optics, thiab tam sim no qhia rau koj, kuv vam tias cov phooj ywg yuav nyiam nws.
Tsis ntev los no, muaj xov xwm hais tias pab pawg kws tshawb fawb ntawm National Physical Laboratory hauv tebchaws United Kingdom, lawv thaum kawg tau tsim ib lub cuab yeej hu ua optical ring resonator los ntawm kev tshawb fawb, lub tshuab no zoo heev, hauv lub cuab yeej sab hauv lub teeb pulse tuaj yeem tig ib puag ncig ib leeg, thiab qhov no ua ke tuaj yeem tswj tus cwj pwm ntawm lub teeb, uas yog ib qho thev naus laus zis tshiab.
Cov kev tshawb fawb tshiab no tau pab cov kws tshawb fawb ntau yam, ua rau cov kws tshawb fawb siv lub teeb kom raug dua, kom lawv thiaj li tau txais cov thev naus laus zis tshiab ntawm theem kev txawj ntse, xws li cov kws tshawb fawb siv tau cov thev naus laus zis no los tsim cov voj voog kho qhov muag tshiab. Ua li no, peb tuaj yeem ua qee yam khoom tshiab, thiab txawm tias ua qee qhov kev tshawb pom tshiab hauv kev kho qhov muag, kom qee qhov kev paub tshiab ntawm kev kho qhov muag.
Yog li ntawd, muaj dab tsi tshiab txog qhov kev ua no? Qhov tseeb, lub teeb tuaj yeem ua rau pom qee qhov kev sib npaug ntawm lub cev uas cov kws tshawb fawb tau tshawb pom. Piv txwv li, lub teeb tuaj yeem ua tib yam hauv ob qho kev taw qhia ntawm lub sijhawm, uas yog, ob lub sijhawm tsis cuam tshuam rau tag nrho lub xeev ntawm lub teeb, thiab qhov no paub rau cov kws tshawb fawb tias yog kev sib npaug ntawm lub sijhawm tig rov qab. Tib lub sijhawm, cov kws tshawb fawb tau tshawb pom tias lub teeb tuaj yeem mus ncig ua nthwv dej, nrog rau polarization, qhov tseeb, kev sib npaug.
Tam sim no cov kws tshawb fawb tab tom ua haujlwm rau cov cuab yeej uas tuaj yeem rhuav tshem cov qauv no, uas yog ib kauj ruam loj rau pem hauv ntej. Rau peb kawm ntau yam kev coj cwj pwm ntawm lub teeb, muaj kev pab zoo heev, tam sim no cov cuab yeej no nyob rau theem pib ntawm kev tshawb fawb thiab kev txhim kho, muaj ntau qhov tsis txaus, tab sis tsawg kawg hauv thaj chaw ntawm optics tuaj yeem coj cov kws tshawb fawb txoj kev tshawb fawb tshiab, yog li qhov no yog qhov chaw tshiab tshaj plaws.
Cov cuab yeej no tuaj yeem hloov lub sijhawm sib xws ntawm lub teeb, nrog rau qhov tshwm sim polarization, yog li cov kws tshawb fawb xav tias qhov kev tshawb fawb no yuav coj kev pab ntau dua rau kev tsim cov moos atomic, tab sis kuj tuaj yeem ua lub luag haujlwm hauv cov khoos phis tawj quantum,Electro-Optic, yog li no kev tshawb fawb thiab thev naus laus zis no tseem ceeb heev, thiab nws tsim nyog kawm ntxiv.
