Izindlela zokuhlaziya ezibonakalayo zibalulekile emphakathini wanamuhla ngoba zivumela ukuhlonza izinto ngokushesha nangokuphephile ezintweni eziqinile, uketshezi noma amagesi. Lezi zindlela zithembele ekukhanyeni okuhlangana ngendlela ehlukile nalezi zinto ezingxenyeni ezahlukene ze-spectrum. Isibonelo, i-ultraviolet spectrum inokufinyelela okuqondile ekushintsheni kwe-elekthronikhi ngaphakathi kwento, kuyilapho i-terahertz ibucayi kakhulu ekudlidlizeni kwama-molecule.
Isithombe sobuciko se-mid-infrared pulse spectrum ngemuva kwensimu kagesi ekhiqiza i-pulse
Ubuchwepheshe obuningi obuthuthukisiwe eminyakeni edlule buvumele i-hyperspectroscopy kanye ne-imaging, okuvumela ososayensi ukuthi babone izenzakalo ezifana nokuziphatha kwama-molecule njengoba egoqeka, ejikeleza noma edlidliza ukuze baqonde izimpawu zomdlavuza, amagesi okushisa, ukungcola, ngisho nezinto eziyingozi. Lobu buchwepheshe obuzwela kakhulu bubonakale buwusizo ezindaweni ezifana nokuthola ukudla, ukuzwa kwamakhemikhali, ngisho nefa lamasiko, futhi bungasetshenziswa ukutadisha isakhiwo sezinto zakudala, imidwebo, noma izinto eziqoshiwe.
Inselele yesikhathi eside kube ukuntuleka kwemithombo yokukhanya emincane ekwazi ukumboza ububanzi obukhulu kangaka be-spectral kanye nokukhanya okwanele. Ama-synchrotron angahlinzeka ngembobo ye-spectral, kodwa ayinakho ukuhambisana kwesikhathi kwama-laser, futhi imithombo yokukhanya enjalo ingasetshenziswa kuphela ezindaweni ezinkulu zabasebenzisi.
Ocwaningweni lwakamuva olushicilelwe ku-Nature Photonics, ithimba lamazwe ngamazwe labacwaningi abavela kwi-Spanish Institute of Photonic Sciences, i-Max Planck Institute for Optical Sciences, i-Kuban State University, kanye ne-Max Born Institute for Nonlinear Optics kanye ne-Ultrafast Spectroscopy, phakathi kwabanye, babika umthombo womshayeli we-mid-infrared ohlangene, okhanya kakhulu. Ihlanganisa i-inflatable anti-resonant ring photonic crystal fiber ne-nonlinear crystal entsha. Le divayisi inikeza i-spectrum ehlangene kusuka ku-340 nm kuya ku-40,000 nm ngokukhanya kwe-spectral okuphindwe kabili kuya kahlanu okuphakeme kunenye yamadivayisi agqamile kakhulu e-synchrotron.
Izifundo zesikhathi esizayo zizosebenzisa isikhathi esincane sokushaya kwenhliziyo komthombo wokukhanya ukwenza ukuhlaziywa kwesikhathi kwezinto nezinto zokwakha, okuvula izindlela ezintsha zezindlela zokulinganisa eziningi ezindaweni ezifana ne-molecule spectroscopy, i-physical chemistry noma i-solid state physics, kusho abacwaningi.
