Cov txheej txheem kho qhov muag yog qhov tseem ceeb rau lub neej niaj hnub no vim tias lawv tso cai rau kev txheeb xyuas sai thiab nyab xeeb ntawm cov khoom hauv cov khib nyiab, kua lossis roj. Cov txheej txheem no cia siab rau lub teeb sib txawv nrog cov tshuaj no hauv ntau qhov chaw ntawm spectrum. Piv txwv li, lub ultraviolet spectrum muaj ncaj qha mus rau hluav taws xob hloov nyob rau hauv ib yam khoom, thaum terahertz yog rhiab heev rau molecular vibrations.
Ib daim duab kos duab ntawm nruab nrab-infrared mem tes spectrum nyob rau hauv keeb kwm yav dhau ntawm hluav taws xob teb uas tsim cov mem tes
Ntau lub thev naus laus zis tau tsim nyob rau xyoo tas los tau ua kom muaj kev saib xyuas hyperspectroscopy thiab duab, tso cai rau cov kws tshawb fawb los soj ntsuam cov xwm txheej xws li kev coj tus cwj pwm ntawm cov molecules thaum lawv quav, kiv lossis vibrate kom nkag siab txog cov cim mob qog noj ntshav, lub tsev xog paj, cov pa phem, thiab txawm tias muaj teeb meem. Cov thev naus laus zis thev naus laus zis no tau ua pov thawj muaj txiaj ntsig zoo hauv thaj chaw xws li kev tshawb nrhiav zaub mov, biochemical sensing, thiab txawm tias kab lis kev cai cuab yeej cuab tam, thiab tuaj yeem siv los kawm cov qauv ntawm cov khoom qub qub, cov duab kos duab, lossis cov ntaub ntawv sculptural.
Ib qho kev sib tw ntev ntev yog qhov tsis muaj lub teeb pom kev zoo uas muaj peev xwm los npog xws li qhov loj spectral ntau thiab qhov ci txaus. Synchrotrons tuaj yeem muab kev pabcuam spectral, tab sis lawv tsis muaj kev sib raug zoo ntawm lub sijhawm ntawm lasers, thiab cov teeb pom kev zoo li no tsuas yog siv tau rau hauv cov neeg siv khoom loj.
Hauv kev tshawb fawb tsis ntev los no tau tshaj tawm hauv Nature Photonics, ib pab neeg tshawb fawb thoob ntiaj teb los ntawm Spanish Institute of Photonic Sciences, Max Planck Institute rau Optical Sciences, Kuban State University, thiab Max Born Institute for Nonlinear Optics thiab Ultrafast Spectroscopy, thiab lwm yam, tshaj tawm compact, high-brightness nruab nrab-infrared tsav qhov chaw. Nws ua ke ib qho inflatable anti-resonant nplhaib photonic siv lead ua fiber nrog ib qho tshiab nonlinear siv lead ua. Cov cuab yeej xa cov spectrum coherent los ntawm 340 nm mus rau 40,000 nm nrog spectral brightness ob mus rau tsib qhov kev txiav txim ntawm qhov loj dua ib qho ntawm cov khoom siv synchrotron brightest.
Cov kev tshawb fawb yav tom ntej yuav siv lub teeb ci lub sij hawm tsawg lub sij hawm mem tes los ua lub sij hawm soj ntsuam ntawm cov khoom thiab cov ntaub ntawv, qhib txoj hauv kev tshiab rau kev ntsuas ntau yam hauv thaj chaw xws li molecular spectroscopy, chemistry lub cev lossis lub xeev physics, cov kws tshawb fawb tau hais.
