Raws li ib qho thev naus laus zis siv dav hauvkev kho qhov muag, spectroscopy thiab lwm yam teb, grating technology muaj ntau qhov zoo tseem ceeb, cov hauv qab no yog cov ntsiab lus ntxaws ntxaws ntawm cov txiaj ntsig ntawm grating technology:
Ua ntej, cov thev naus laus zis grating siab muaj cov yam ntxwv ntawm kev ua haujlwm siab, uas yog vim muaj cov qauv zoo ntawm cov grating thiab cov txheej txheem tsim khoom meej. Cov grating siab daws teeb meem tuaj yeem ntes cov kev hloov pauv me me thiab kev hloov chaw, yog li ua lub luag haujlwm tseem ceeb hauv kev ntsuas qhov tseeb, kev tshawb pom qhov muag thiab lwm yam teb. Qhov kev ua haujlwm siab no ua rau cov thev naus laus zis grating ua qhov zoo dua hauv cov ntawv thov uas xav tau kev ua haujlwm siab.
Qhov kev tsim qauv grating zoo tshaj plaws tuaj yeem txhim kho qhov ua tau zoo ntawm lub teeb diffraction thiab txo qhov poob ntawm lub zog teeb. Lub grating ua haujlwm siab ua rau lub cuab yeej kho qhov muag tau txais lub teeb liab muaj zog dua nyob rau hauv tib qho xwm txheej, txhim kho qhov rhiab heev thiab kev ua haujlwm ntawm lub cuab yeej. Tsis tas li ntawd, cov yam ntxwv ntsuas tsis sib cuag ntawm lub grating tiv thaiv kev hnav thiab deformation ntawm qhov chaw ntawm cov khoom, txhim kho qhov ua tau zoo thiab qhov tseeb ntawm kev ntsuas.
Qhov thib peb, cov thev naus laus zis grating ntau yam muaj cov yam ntxwv ntawm ntau yam kev ua haujlwm. Ntau hom gratings, xws li holographic gratings, yog tsim los npog ntau yam spectral thiab haum rau ntau lub wavelengths ntawm lub teeb. Qhov no ua rau lub grating ua lub luag haujlwm hauv ntau yamdaim ntawv thov kho qhov muag, thiab txhim kho qhov kev hloov pauv tau yooj yim thiab kev siv tau ntawm lub grating. Tsis tas li ntawd,kev siv tshuab gratingtuaj yeem ua ke nrog lwm cov thev naus laus zis kho qhov muag kom ua tiav cov haujlwm nyuaj thiab siab dua. Cov txheej txheem tsim khoom ntawm fiber Bragg grating yog qhov paub tab, yooj yim rau kev tsim khoom, thiab tus nqi qis dua. Qhov no ua rau cov thev naus laus zis grating yooj ywm dua thiab pheej yig dua hauv kev tsim khoom lag luam thiab daim ntawv thov. Tib lub sijhawm, kev saib xyuas cov thev naus laus zis grating yog qhov yooj yim thiab yooj yim, txo cov nqi siv thiab kev nyuaj txij nkawm.
Kev ntseeg siab thiab kev hloov pauv ib puag ncig Cov thev naus laus zis Grating muaj qhov zoo ntawm kev ntseeg siab thiab kev hloov pauv ib puag ncig. Fiber grating tsis cuam tshuam los ntawm ib puag ncig noo noo, tuaj yeem zam kev cuam tshuam ntawm lub zog hluav taws xob, muaj cov yam ntxwv rwb thaiv tsev zoo.
Ntxiv rau, cov fiber grating kuj muaj cov yam ntxwv ntawm kev ua haujlwm zoo, muaj zog tiv taus qhov chaw ib puag ncig hnyav thiab kev puas tsuaj ntawm cov tshuaj lom neeg. Qhov no ua rau cov thev naus laus zis grating tswj tau qhov ua tau zoo thiab ua haujlwm hauv ntau qhov chaw nyuaj. Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, cov thev naus laus zis grating kuj tseem niaj hnub tsim kho tshiab thiab txhim kho. Cov thev naus laus zis grating niaj hnub muaj cov yam ntxwv ntawm kev txawj ntse thiab kev koom ua ke. Los ntawm kev sib txuas thiab kev sib txuas lus nrog cov khoos phis tawj thiab lwm yam khoom siv ntse, cov thev naus laus zis raster tuaj yeem ua tiav cov ntaub ntawv ua tiav thiab kev tshuaj xyuas ntau dua, muab cov kev daws teeb meem ntau dua thiab raug rau ntau yam xwm txheej thov.
Hauv kev xaus, cov thev naus laus zis grating muaj ntau qhov zoo tseem ceeb, xws li kev ua haujlwm siab, kev ua haujlwm zoo, kev hloov pauv tau yooj yim, kev tsim khoom yooj yim thiab kev saib xyuas, kev ntseeg siab thiab kev hloov pauv ib puag ncig, kev txawj ntse thiab kev koom ua ke. Cov txiaj ntsig no ua rau cov thev naus laus zis grating muaj kev cia siab dav thiab muaj peev xwm txhim kho hauv ntau qhov chaw xws li optics, spectroscopy, kev sib txuas lus thiab kev soj ntsuam.
