Kev Txhim Kho Kev Soj Ntsuam Dej Zoo nrog Photonic Sensing Technologies

Raws li cov teeb meem ib puag ncig thoob ntiaj teb ua rau muaj kev hem thawj rau qhov zoo ntawm dej, muaj kev xav tau ntau ntxiv rau cov kev daws teeb meem zoo. Cov thev naus laus zis photonic sensing tshwm sim ua cov cuab yeej ntsuas dej zoo tiag tiag thiab raug, muab kev nkag siab zoo thiab kev xaiv hauv ntau qhov chaw hauv dej.
Cov Ntsiab Cai ntawm Photonic Sensing Technologies
Cov thev naus laus zis photonic sensing siv cov kev sib cuam tshuam tseem ceeb ntawm lub teeb thiab cov khoom, xws li kev sib kis thiab kev cuam tshuam, los txheeb xyuas cov khoom ntim lossis cov cim qhia txog dej zoo tseem ceeb xws li cov khoom seem tag nrho (TSS).

Cov sensors no siv cov teeb pom kev zoo li LEDs lossis lasers los ci dej, qhov twg qhov loj thiab cov khoom sib xyaw ntawm cov khoom tsis huv cuam tshuam rau kev sib cuam tshuam ntawm lub teeb, ua rau muaj kev hloov pauv ntawm lub teeb ci lossis qhov ntev ntawm lub teeb.

Cov kev hloov pauv no ces raug sau tseg siv ntau txoj kev nrhiav pom, suav nrog photodiodes, phototransistors, lossis charge-coupled devices (CCDs), uas ntsuas qhov muaj zog ntawm lub teeb tom qab cuam tshuam nrog cov pa phem. Cov fibers optical feem ntau siv los coj lub teeb mus rau thiab los ntawm cov qauv dej, tso cai rau kev tshawb pom deb lossis faib tawm.

Ntxiv rau kev ntsuas qhov kev sib kis ntawm lub teeb thiab kev cuam tshuam ntawm lub teeb, qee lub photonic sensors siv cov teeb pom kev zoo tshwj xeeb los ntes cov pa phem. Piv txwv li, cov sensors fluorescence ua rau cov molecules fluorescent hauv dej muaj lub teeb ntawm ib qho wavelength tshwj xeeb thiab ntsuas qhov muaj zog ntawm cov fluorescence uas tawm los, uas tuaj yeem cuam tshuam nrog qhov concentration ntawm cov pa phem tshwj xeeb.

Ntawm qhov tod tes, cov sensors ntawm qhov chaw plasmon resonance (SPR) saib xyuas qhov sib txawv ntawm cov refractive index ntawm qhov chaw hlau uas yog los ntawm kev sib txuas ntawm cov molecules lub hom phiaj, muab txoj hauv kev kuaj pom tsis muaj daim ntawv lo thiab lub sijhawm tiag tiag.

Peb tuaj yeem muab cov ntsuas dej zoo nrog ntau yam kev ntsuas rau ntau yam kev siv, raws li hauv qab no
