Nyob rau hauv biomedical optical detection technology siv spectral tsom xam, muaj peb tus neeg sawv cev kev tsom xam txoj kev UV-pom spectrophotometry (photoelectric colorimetry), fluorescence tsom xam, raman tsom xam, raws li, kom ua tiav ntau theem ntawm biomedical nrhiav kom tau cov ntaub so ntswg, hlwb thiab molecules. Cov ntxaij lim dej kho qhov muag tau siv nyob rau hauv peb qhov kev tshuaj ntsuam biomedical saum toj no. Cov ntxaij lim dej kho qhov muag yog cov cuab yeej tseem ceeb uas txiav txim siab qhov tseeb thiab kev ntseeg siab ntawm biomedical detection systems. Cov lus hauv qab no teev cov kev siv tau ntawm peb txoj kev tshawb nrhiav biomedical thiab cov kev xav tau rau lawv cov lim dej kho qhov muag.
| Biomedical xeem txoj kev | Optical phenomena siv | Daim ntawv thov teb | Lim cov ntsiab lus tseem ceeb | Feem ntau ntawm cov txheej txheem rau ib txheej txheej |
| UV-Vis spectrophotometric tsom xam | lub teeb absorption | Cov ntaub so ntswg biochemical ntsuas ntsuas | Bandwidth ntawm 8 ~ 10nm nqaim band kis tau tus mob cutoff band qhov tob tshaj OD6, ib puag ncig adaptability yuav tsum tau ntawm ya raws tsis hloov | 30 ~ 50 |
| Fluorescence tsom xam | Fluorescence emission | Cellular, DNA amplification | Bandwidth ntawm 20 ~ 40nm kis tau tus mob, excitation, emission sharp cutoff (90% ~ 0D6 1 ~ 2%); cutoff band sib sib zog nqus cutoff, me me noo noo nqus drift | 50 ~ 100 |
| Raman tsom xam | Raman tawg | Qhov tseeb ntsuas ntawm molecular zog theem qauv ntawm cov teeb meem hom nrhiav kom tau | Ntse emission cutoff (90% ~ 0D6 0.5 ~ 1%), me me noo noo nqus drift | 100-150 |
