Daim ntawv thov ntawm Polarization tuav Fiber
01 Fiber Optic Gyroscope
Ib qho ntawm cov kev siv feem ntau ntawm polarization-tswj fibers yog los tsim cov khoom siv fiber ntau hauv fiber ntau-optic gyroscopes
02 Fiber Laser tej tshuab
Polarization-tswj fibers tau dav siv hauv fiber ntau lasers vim lawv cov khoom tshwj xeeb polarization. Laser polarization-kev tuav pov hwm fibers tuaj yeem muab faib ua ytterbium-doped, thulium-doped, erbium-ytterbium co-doped polarization-tswj fibers, loj hom teb cheeb tsam ytterbium-doped polarization-tseem photonic siv lead ua fibers, passive txuam polarization-tso fibers, thiab lwm yam ..
03 Tam sim no Transformer (FOCT)
Zoo ib yam li fiber ntau optic gyroscopes, daim ntawv thov ntawm polarization-tswj fibers nyob rau hauv tam sim no transformers kuj yog ib tug sensing fiber voj. Tab sis qhov sib txawv ntawm ob yog tias lub nplhaib muaj fiber ntau ntawm no tuaj yeem tsim los ntawm kev sib hloov polarization-tswj fiber ntau, thiab tag nrho cov kab ke siv Faraday magneto-optical nyhuv, uas yog, cov hlau nplaum tsim los ntawm cov neeg nqa khoom tam sim no yuav. ua rau lub xeev polarization ntawm lub teeb kis hauv lub nplhaib fiber ntau hloov pauv. Kev sib hloov tshwm sim. Txij li tam sim no nyob rau hauv lub tam sim no tus neeg xyuas pib yog proportional rau lub generated magnetic teb, qhov loj ntawm tam sim no yuav xam tau los ntawm kev saib xyuas lub polarization rotation kaum sab xis ntawm lub teeb.
04 Integrated optics
Integrated Optics yog ib qho tseem ceeb daim ntawv thov ntawm polarization tswj fibers. Lithium niobate (LiNbO3) modulator yog ib yam khoom siv kho qhov muag. Titanium dioxide-doped waveguides yog diffused nyob rau hauv lub lithium niobate nti, thiab cov pigtails ntawm lub polarization-tswj fibers muab ib tug ruaj khov polarization xeev thiab ua raws li cov nti lub birefringence axis. Lub functionality ntawm cov cuab yeej yog raws li Pockels nyhuv: thaum ib tug voltage yog siv rau cov electrodes, lub refractive index ntawm lub substrate hloov nyob rau hauv feem rau qhov voltage, thiab qhov tshwm sim ntawm kev hloov nyob rau hauv lub zoo optical txoj kev ntev yuav siv tau los tsim kev cuam tshuam. , raws li doped titanium dioxide Lub meej tsim ntawm waveguides yuav manipulated los muab kev hloov ntawm theem, zaus los yog amplitude, los yog txawm hloov kho qhov muag lub hwj chim ntawm raws.
05 Optical fiber txaus sensor
Polarization-tswj fibers kuj tseem siv tau rau lwm hom fiber ntau-optic sensing systems. Piv txwv li, Laser Doppler Velocimetry, uas yog siv los ntsuas qhov nrawm nrawm, txiav txim siab qhov nrawm nrawm ntawm huab cua lossis ntshav hauv cov hlab ntsha los ntawm kev ntsuas Doppler zaus hloov ntawm lub teeb tawg los ntawm cov kua dej.
06 Kev thov kho mob
Hauv cov tshuaj, cov kws kho mob tuaj yeem siv cov catheters tshwj xeeb lossis "cov xov hlau qhia" los kuaj xyuas cov neeg mob uas muaj kab mob plawv. Qhov no yog hu ua OCT (Optical Coherence Tomography, optical coherence tomography. OCT siv low-coherence (broadband) light, polarization-maintaining fiber kuj plays lub luag haujlwm tseem ceeb hauv nws, thiab cov kws phais tuaj yeem paub qhov txawv ntawm cov hlab ntsha phab ntsa thiab cov hlab ntsha occlusion. los ntawm OCT, uas yog qhov tsim nyog rau kev kho mob ntxiv.
07 Tshuaj ntsuam xyuas muaj pes tsawg leeg
Ua kom zoo dua ntawm cov yam ntxwv uas cov khoom tshwj xeeb yuav hnov mob nrog qee yam khoom lossis adsorb rau ib leeg, polarization-tswj fiber ntau kuj tuaj yeem siv rau kev tshawb nrhiav cov tshuaj muaj pes tsawg leeg. Kev kuaj xyuas hydrogen ua piv txwv, palladium hlau txheej (Pd txheej) yuav nqus cov hydrogen thiab nthuav dav, uas yuav ua rau muaj kev hloov pauv ntawm birefringence B ntawm cov polarization-tswj fiber ntau uas nws ua raws. Los ntawm kev txheeb xyuas qhov kev hloov pauv no, nws tuaj yeem txheeb xyuas seb cov pa roj muaj hydrogen thiab nws cov ntsiab lus. .
