Cov yam ntxwv ntawm optical nyias zaj duab xis suav nrog cov yam ntxwv ntawm cov khoom siv kho qhov muag, cov khoom siv kho qhov muag thiab cov khoom tsis yog kho qhov muag, cov khoom siv kho qhov muag tsuas yog xa mus rau spectral reflectance, transmittance thiab optical poob (kev nqus poob thiab kev xav tsis zoo) cov khoom ntawm optical nyias zaj duab xis. Transmittance thiab reflectance yog qhov yooj yim tshaj plaws ntawm cov khoom siv kho qhov muag ntawm cov yeeb yaj kiab nyias nyias, yog li kev ntsuam xyuas ntawm nyias zaj duab xis xa tawm thiab kev cuam tshuam yog cov txheej txheem sim cov txheej txheem rau cov yeeb yaj kiab nyias. Optical parameters ntawm optical nyias zaj duab xis muaj xws li refractive index, absorption coefficient thiab zaj duab xis thickness ntawm optical nyias zaj duab xis. Vim yog qhov sib txawv ntawm stoichiometric nyob rau hauv cov khoom siv ntawm optical nyias zaj duab xis npaj los ntawm cov txheej txheem tiag tiag, cov qauv tsis yog homogeneous thiab ntom, tab sis muaj cov microstructures thiab ntau yam tsis xws luag, lub dielectric zaj duab xis txheej tsis yog tag nrho pob tshab, thiab muaj ib tug tsis muaj zog nqus, thaum muaj spatial non-uniformity thiab theem ntawm cov zaj duab xis yog tsis muaj zog thiab anisotropy. infinite thiab du interface. Qhov tseem ceeb tshaj, nyob rau hauv cov txheej txheem kev npaj tiag tiag, cov txheej txheem kev npaj cov yeeb yaj kiab tsis muaj qhov cuam tshuam loj heev rau qhov tsis pom kev ntawm cov yeeb yaj kiab, yog li qhov kev pom zoo ntawm lub sijhawm tiag tiag ntawm qhov tsis pom kev ntawm cov yeeb yaj kiab yog qhov tseem ceeb heev. Nyob rau hauv tas li ntawd, lub optical nyias zaj duab xis raws li ib tug ntaus ntawv siv nyob rau hauv lub tiag tiag ib puag ncig, nyob rau hauv tas li ntawd mus rau lub kho qhov muag yam ntxwv ntawm cov cuab yeej yuav tsum tau raws li qhov yuav tsum tau, cov zaj duab xis muaj ntau lwm yam tseem ceeb uas tsis yog-optical yam ntxwv cuam tshuam rau kev siv ntawm cov zaj duab xis, xws li adhesion, zaj duab xis kev nyuaj siab, zaj duab xis hardness thiab nto roughness thiab zaj duab xis muaj peev xwm tiv taus ib puag ncig thiab lwm yam. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau ua kom raug ntsuas txhua qhov ntau yam tsis muaj lossis cov yam ntxwv uas cuam tshuam rau kev siv cov khoom siv nyias nyias.
Transmittance thiab reflectance ntawm nyias zaj duab xis yog tsuas yog kev sim siv spectral test analyzers. Spectral analyzers rau kev soj ntsuam cov yeeb yaj kiab kho qhov muag tuaj yeem muab faib ua UV-Vis spectrophotometers, infrared spectrophotometers thiab infrared Fourier spectrometers raws li cov kab sib txawv. Thawj ob siv spectral spectroscopy hauv paus ntsiab lus ntawm kev tsom xam thiab kev sim, tom kawg raws li txoj cai ntawm kev cuam tshuam spectral tsom xam system. Vim yog cov qauv geometric sib txawv thiab cov duab ntawm cov khoom siv nyias nyias, txawm hais tias txhua qhov kev xa tawm thiab kev ntsuas kev cuam tshuam, tab sis rau cov duab sib txawv, qhov sib txawv ntawm qhov sib txawv los yog qhov sib txawv ntawm cov polarization, yuav xav tau cov kev sim thiab cov txheej txheem sib txawv.
