I-50/50 Beamsplitter ye-optical coherence tomography(OCT)
Umbukiso Womkhiqizo
Incazelo Yomkhiqizo
I-50/50 ye-beam splitter iyisisetshenziswa sokubona esihlukanisa ukukhanya kube izindlela ezimbili ngamandla acishe alingane—50% adluliselwe futhi 50% abonakale. Idizayinelwe ukuqinisekisa ukuthi ukukhanya kusakazwa ngokulinganayo phakathi kwemizila yokuphumayo, igcina ibhalansi edingekayo ukuze kukale izilinganiso ezinembile kanye nesithombe esicacile. Lesi silinganiso sokuhlukanisa sizuzisa kakhulu ezinhlelweni zokusebenza lapho ukugcinwa kokukhanya kuzo zombili izindlela kubalulekile, njengamasistimu wokuxilonga izithombe.
Ukunemba nokunemba:Ukusatshalaliswa okulinganayo kokukhanya kuqinisekisa ukuthi imishini yokuxilonga yezokwelapha ingaveza imiphumela ethembekile, ekwazi ukukhiqiza kabusha. Kungakhathaliseki ukuthi ithwebula ukukhishwa kwe-fluorescence okucacile noma ikhiqiza izithombe ezinemininingwane yezicubu ngo-OCT, isihlukanisi se-50/50 se-50 siqinisekisa ukuthi ukukhanya kusatshalaliswa kahle, kuqinisekisa idatha yokuxilonga yekhwalithi ephezulu.
I-Non-Polarizing Design:Ukuxilongwa okuningi kwezokwelapha kuncike ekukhanyeni okunezimo ezihlukene ze-polarization. Izihlukanisi ezingama-50/50 ze-Non-polarizing 50/50 zisusa ukuncika kwe-polarization, ziqinisekisa ukusebenza okungaguquki kungakhathaliseki ukuthi ukukhanya ku-polarization. Lesi sici sibaluleke kakhulu kumasistimu afana ne-fluorescence microscopy, lapho imiphumela ye-polarization ingase iphazamise ukunemba kwesithombe.
Ukusebenza Okuphezulu kanye Nokulahlekelwa Okuphansi:Ukuxilongwa kwezokwelapha ngokuvamile kufuna amazinga aphezulu kakhulu okusebenza kokubona. Ikhwalithi ephezulu ye-50/50 ye-beam splitter inciphisa ukulahlekelwa kokufaka, iqinisekisa ukuthi ukukhanya okwengeziwe kuyadluliselwa futhi kuboniswa ngaphandle kokuwohloka. Ukulahleka kokufakwa okujwayelekile kungaphansi kuka-0.5 dB, okuqinisekisa ukuthi isistimu isebenza ngempumelelo enkulu.
Izixazululo Ezenzeka Ngokwezifiso:Ngokuya ngezidingo ezithile zohlelo lwezokwelapha, ama-splitter angama-50/50 angenziwa ngokwezifiso ngokuya ngosayizi, ububanzi be-wavelength, kanye nesilinganiso sokuhlukanisa. Lokhu kuvumelana nezimo kuqinisekisa ukuthi okokusebenza kwakho kokuxilonga kuthola ngqo ukusebenza okudingayo, noma ngabe udinga isihlukanisi se-broadband noma esidizayinelwe ibanga elithile le-wavelength, njengokukhanya okubonakalayo noma okuseduze kwe-infrared.
Ukusetshenziswa kwezihlukanisi ze-50/50 ze-beam ekuxilongweni kwezokwelapha kudlala indima ebalulekile ekuqinisekiseni ukuthi amasistimu okubona asebenza namazinga aphezulu okunemba nokuthembeka. Kungakhathaliseki ukuthi i-fluorescence microscopy, i-optical coherence tomography, noma i-endoscopic imaging, lezi zihlukanisi ze-beam ziqinisekisa ukuthi ukukhanya kusakazwa ngokulinganayo, kuhlinzeka odokotela nochwepheshe bezokwelapha ngamathuluzi abawadingayo ukuze bathole ukuxilonga okunembile kanye nokuhlela ukwelashwa okuphumelelayo.
Kwa-Jiujon Optics, sisebenza ngokukhethekile ekuhlinzekeni ngezihlukanisi ze-beam ezisezingeni eliphezulu ezingu-50/50 embonini yokuxilonga ngezokwelapha. Imikhiqizo yethu yenzelwe ukuhlangabezana nezidingo eziqine kakhulu zemishini yezokwelapha yesimanje, iqinisekisa ukuthi uthola okuningi ezinhlelweni zakho zokubona.
