Te tikanga whakamahi owhakakaha whatu haurua-haurua(SOA) penei:
E whakamahia whānuitia ana te whakakaha whatu haurua-haurua SOA i ngā āhuatanga katoa o te ao. Ko tētahi o ngā ahumahi tino nui ko te whakawhitiwhiti kōrero, e whai hua ana i roto i te ara me te whakawhiti.Whakakaha whatu haurua-haurua SOAe whakamahia ana hoki hei whakarei ake, hei whakanui rānei i te putanga tohu o ngā whakawhitiwhiti muka whatu tawhiti, ā, he whakakaha whatu tino hira.
Ngā taahiraa whakamahinga taketake
Kōwhiria te mea e tika anaWhakakaha whatu SOAI runga i ngā āhuatanga me ngā whakaritenga tono motuhake, whiriwhiria he whakakaha whatu SOA me ngā tawhā e tika ana pēnei i te roangaru mahi, te whakanui, te mana putanga kua kōtui, me te tau haruru. Hei tauira, i roto i ngā pūnaha whakawhitiwhiti whatu, ki te whakahaerehia te whakakaha tohu i roto i te roopu 1550nm, me whiriwhiri he whakakaha whatu SOA me te roangaru mahi e tata ana ki tēnei awhe.
Hononga i te ara whatu: Honoa te pito whakauru o te whakakaha whatu haurua-haurua SOA ki te pūtake tohu whatu e hiahia ana kia whakakahangia, ka honoa te pito putanga ki te ara whatu, ki te taputapu whatu rānei e whai ake nei. I te wā e hono ana, kia aro ki te whai huatanga o te hononga o te muka whatu, me te ngana ki te whakaiti i te ngaronga whatu. Ka taea te whakamahi i ngā taputapu pēnei i ngā hononga muka whatu me ngā wehewehe whatu hei arotau i ngā hononga ara whatu.
Whakatakotoria te iahiko whakahāngai: Whakahaerehia te whakanui o te whakakaha SOA mā te whakarerekē i tōna iahiko whakahāngai. I te nuinga o te wā, ko te nui ake o te iahiko whakahāngai, ko te teitei ake o te whakanui, engari i te wa ano, ka piki ake pea te haruru me ngā huringa o te mana putanga kua kōtui. Me kimi te uara iahiko whakahāngai e tika ana i runga i ngā whakaritenga tuturu me ngā tawhā mahi oWhakakaha SOA.
Aroturuki me te whakarerekētanga: I te wā e whakamahia ana, me aroturuki te mana whatu putanga, te whakanui, te haruru me ētahi atu tawhā o te SOA i te wā tūturu. I runga i ngā hua aroturuki, me whakarerekē te iahiko piro me ētahi atu tawhā kia mau ai te mahi pumau me te kounga tohu o te whakakaha whatu haurua-haurua SOA.
Te whakamahinga i roto i ngā horopaki tono rerekē
Pūnaha whakawhitiwhiti kōrero whatu
Whakakaha mana: I mua i te tukunga o te tohu whatu, ka whakanohoia te whakakaha whatu haurua-haurua SOA ki te pito tuku hei whakanui ake i te mana o te tohu whatu me te whakaroa i te tawhiti tuku o te pūnaha. Hei tauira, i roto i te whakawhitiwhiti muka whatu tawhiti, mā te whakanui ake i ngā tohu whatu mā te whakakaha whatu haurua-haurua SOA ka taea te whakaiti i te maha o ngā teihana tuku.
Whakakaha aho: I roto i ngā aho tuku whatu, ka whakanohoia he SOA i ētahi wā hei utu mō te ngaronga i puta mai i te ngoikore o te muka me ngā hononga, kia pai ai te kounga o ngā tohu whatu i te wā e tuku tawhiti ana.
Whakakaha-mua: I te pito whiwhi, ka whakatakotoria te SOA ki mua i te kaiwhiwhi whatu hei whakakaha-mua hei whakarei ake i te aro o te kaiwhiwhi me te whakapai ake i tōna kaha ki te kite i ngā tohu whatu ngoikore.
2. Pūnaha pūoko whatu
I roto i te whakawehewehe muka Bragg grating (FBG), ka whakanuia e te SOA te tohu whatu ki te FBG, ka whakahaere i te ahunga o te tohu whatu mā te porohita, ā, ka rongo i ngā huringa o te roangaru, te wā rānei o te tohu whatu i puta mai i ngā rerekētanga pāmahana, taumahatanga rānei. I roto i te kimi mārama me te whānuitanga (LiDAR), ka taea e te whakakaha whatu SOA whaiti, ina whakamahia tahi me ngā taiaho DFB, te whakarato i te mana putanga teitei mō te kimi tawhiti roa.
3. Te hurihanga o te roangaru
Ka tutuki te hurihanga roangaru mā te whakamahi i ngā pānga kore-raina pērā i te whakarerekētanga whakawhiti-whakanui (XGM), te whakarerekētanga whakawhiti-wāhanga (XPM), me te whakaranu ngaru-whā (FWM) o te whakakaha whatu SOA. Hei tauira, i roto i te XGM, ka werohia he hihi mārama kite ngaru tonu ngoikore me te hihi mārama papu kaha ki roto i te whakakaha whatu SOA i te wā kotahi. Ka whakarerekētia te papu, ka whakamahia ki te mārama kite mā te XGM hei whakatutuki i te hurihanga roangaru.
4. Kaihanga pāoro whatu
I roto i ngā hononga whakawhitiwhitinga wehewehenga roangaru OTDM tere-teitei, ka whakamahia ngā mowhiti muka raka-aratau kei roto ko te whakakaha whatu SOA hei whakaputa i ngā pātere roangaru ka taea te whakarerekē i te tere whakahokinga teitei. Mā te whakarerekē i ngā tawhā pēnei i te ia o te whakakaha SOA me te auau whakarerekētanga o te taiaho, ka taea te whakatutuki i te putanga o ngā pātere whatu o ngā roangaru rerekē me ngā auau whakahokinga.
5. Whakaora karaka whatu
I roto i te pūnaha OTDM, ka whakahokia mai te karaka mai i ngā tohu whatu tere-teitei mā roto i ngā koropiko raka-wāhanga me ngā pana whatu i whakatinanahia i runga i te whakakaha SOA. Ka honoa te tohu raraunga OTDM ki te whakaata mowhiti SOA. Ko te raupapa pātere whakahaere whatu i hangaia e te taiaho raka-aratau whakarerekē ka akiaki i te whakaata mowhiti. Ka kitea te tohu putanga o te whakaata mowhiti e te photodiode. Ka raka te auau o te oscillator whakahaere-ngaohiko (VCO) i te auau taketake o te tohu raraunga whakauru mā roto i te koropiko raka-wāhanga, ā, ka tutuki te whakaoranga karaka whatu.
