Njengohlobo olulodwa lwesihlungi se-optical, i-double-passisihlungi(eyaziwa nangokuthi isihlungi sokudlulisa) iyithuluzi elibonakalayo elingadlulisela noma libonise ukukhanya ngokukhetha ebangeni elithile lamaza. Ngokuvamile libekwa ngezingqimba ezimbili noma ngaphezulu zefilimu ezincane, ngayinye inezakhiwo ezithile zokukhanya. Linokudlulisa okuphezulu ngaphakathi kwamaza amabili athile wamaza, futhi linezakhiwo zokuvimba kwamanye amaza okukhanya phakathi kwalawa maza amabili.
1.Isimiso sokusebenzakweizihlungi ezidlula kabili
Umgomo wokusebenza wesihlungi esidlula kabili usekelwe kakhulu emphumeleni wokuphazamiseka kwefilimu enezingqimba eziningi. Uma ukukhanya kungena kusihlungi, kuphazamisa phakathi kwezingqimba zefilimu ezahlukene. Ngokuklama nokulawula ukujiya kanye nenkomba yokukhanya kwengqimba yefilimu, kungenzeka ukudlulisa noma ukukhombisa ngokukhetha ukukhanya kobude be-wavelength ethile.
Ngokukhethekile, lapho ubude be-wavelength yokukhanya kwesigameko bufana nobude be-wavelength obusetshenziswa umklamo wesihlungi, ukukhanya kobude be-wavelength efanayo kuzothuthukiswa ngaphakathi kwesihlungi ngomphumela wokuphazamiseka, okuvumela ukuthi kudlule kusihlungi. Ngokuphambene nalokho, ukukhanya kwama-wavelength ahlukene kuzobhujiswa umphumela wokuphazamiseka futhi kufakwe noma kuboniswe yisihlungi.

2.Izici zezihlungi ezidlula kabili
Ukudluliselwa Okukhethiwe Noma Ukuzindla
Ngokusekelwe kumklamo nokukhethwa kwezinto ezibonakalayo, ukudlula kabiliizihlungiingadlulisela noma ibonise ukukhanya ngokukhetha ngaphakathi kwebanga elithile lamaza.
Ukubonakala okuphezulu
Kubhendi yokudlulisa ekhethiwe, ukudlulisa kwesihlungi esidlula kabili kungafinyelela ngaphezu kuka-90%, okungakhetha ngokunembile ukudlulisa noma ukuvimba ubude besikhathi bokukhanya obuthile.
Ukusebenza kahle kakhulu
Izihlungi ezidlula kabili zingafinyelela ukudlulisa okuphezulu noma ukubuyisa okuphezulu, okuzivumela ukuthi zisebenze kahle futhi zilungise ukukhanya ezinhlelweni zokukhanya; ngesikhathi esifanayo, ukusebenza kwazo kushintsha kancane ngaphansi kwezinguquko zemvelo ezifana nokushisa nomswakama, futhi zinokuvikela okuhle kokushisa kanye nokumelana nokugqwala, futhi zingasebenza ngokuzinzile isikhathi eside.
Izici zezihlungi ezidlula kabili
Ububanzi Bomkhawulo Obuncane
Ukudlula kabiliizihlungibane-bandwidth encane yokukhanya ngaphakathi kwebanga elithile lamaza okukhanya, okunikeza ukukhetha okuphezulu kwe-spectral.
3.Ukusetshenziswa kwezihlungi ezidlula kabili
Izihlungi ze-double-pass zisetshenziswa kabanzi emikhakheni eminingi, njenge:
Izicelo zethuluzi lokubona
Izihlungi ezidlula kabili zivame ukusetshenziswa kumathuluzi okukhanya afana nama-spectrometer, ama-microscope, nama-laser ukuhlunga ngokukhetha noma ukudlulisa ukukhanya kwamaza athile.
Kusetshenziswa kumathuluzi okukhanya
Izinhlelo zokusebenza zobuchwepheshe bokuxhumana
Izihlungi ze-double-pass zisetshenziswa emikhakheni yokuxhumana nge-optical fiber, amadivayisi e-optomechanical, njll. ukuthuthukisa ikhwalithi yokuxhumana. Isibonelo, ezinhlelweni zokuxhumana nge-optical fiber, izihlungi ze-double-pass zisetshenziswa kakhulu ukuhlunga ukukhanya kwamaza athile okukhanya ukuze kudluliselwe futhi kuphindaphindwe izimpawu ze-optical.
Izinhlelo zokusebenza zokugcina ulwazi lwe-Optical
Kumadivayisi okugcina ama-optical, izihlungi ze-double-pass zisetshenziswa kakhulu ukufunda noma ukubhala izimpawu ze-optical zama-wavelength athile ngokukhetha.
Izinhlelo zokusebenza ze-Raman spectroscopy ezithuthukisiwe ebusweni
Uma kusetshenziswa i-spectroscopy ye-Raman ethuthukisiwe ebusweni, izihlungi ze-double-pass zithola izimpawu ze-Raman zamaza athile ngokukhanya okukhethayo noma ukudlulisa.
Ngaphezu kwalokho, i-double-passizihlungiZisetshenziswa futhi emikhakheni yesayensi yokuphila njenge-biological microscopy kanye ne-fluorescent probe detection, okungafeza ukutholwa nokubonwa okunembe kakhudlwana.
Imicabango Yokugcina:
Ngokusebenzisana nochwepheshe eChuangAn, kokubili ukuklama kanye nokukhiqiza kuphathwa onjiniyela abanekhono eliphezulu. Njengengxenye yenqubo yokuthenga, ummeleli wenkampani angachaza ngokuningiliziwe ulwazi oluthile mayelana nohlobo lwelensi ofisa ukuyithenga. Uchungechunge lwemikhiqizo yelensi kaChuangAn lusetshenziswa ezinhlobonhlobo zezicelo, kusukela ekuqapheni, ekuskeneni, kuma-drones, ezimotweni kuya emakhaya ahlakaniphile, njll. I-ChuangAn inezinhlobo ezahlukene zamalensi aqediwe, angashintshwa noma enziwe ngezifiso ngokwezidingo zakho. Xhumana nathi ngokushesha okukhulu.
