Fiber Optic Pūoko
Ko te pūoko muka he mea tito he puna marama, he muka maiki, he muka puta, he whakarereke marama, he puhoi rama, he demodulator. Ko te kaupapa matua ko te tuku i te marama o te puna marama ki te waahi whakarereke ma te muka maia, ka pahekoheko te marama ki nga tawhā ine o waho i roto i te rohe whakarereke kia pai ai nga ahuatanga o te marama (penei i te kaha, te roangaru, te auau. , wahanga, ine noa, me etahi atu) ka puta. Ko te rama tohu ka huri hei rama tohu whakarereke, ka tukuna ki te kairapu whakaahua me te demodulator ma te muka puta ki te tiki i nga tawhā ine.
Ka taea te wehewehe i nga pukoro muka whatu ki nga waahanga e rua i runga i te momo hanganga: ko tetahi he pukoro mahi (whakaaro); ko tetahi atu he pukoro kore-mahi (marama-whakawhiti).
Pūoko mahi
Whakamahia te muka whatu (me te muka whatu motuhake ranei) me te tairongo me te kaha ki te kite i nga korero o waho hei huānga mohio ki te whakarereke i te rama e tukuna ana i roto i te muka whatu hei huri i te kaha, te wahanga, te auau, te polarization ranei o te rama tuku. Ma te whakaheke i te tohu whakarereke, ka whiwhi te tohu ine.
Ko te muka whatu ehara i te mea he arataki arataki marama anake, engari he huānga tairongo ano hoki, a ko te nuinga o nga wa ka whakamahia te muka whatu aratau maha.
Painga: hanganga kiato me te tairongo tiketike. Nga ngoikoretanga: Ko nga muka whatu motuhake e hiahiatia ana, he nui te utu. Tauira angamaheni: muka whatu gyroscopes, muka whatu hydrophones, etc.
pūoko kore-mahi
Ka whakamahia etahi atu waahanga tairongo ki te mohio ki nga huringa e ine ana. Ka whakamahia noa te muka whatu hei reo tuku korero, ka whakamahia te muka whatu aratau kotahi. Ko te muka whatu anake te whai waahi ki te arahi i te rama, ka inehia te rama me te whakarereke i runga i te huānga tairongo momo muka whatu.
Painga: Kaore he hiahia mo nga muka whatu motuhake me etahi atu hangarau motuhake, he ngawari ki te whakatinana, me te utu iti. Nga huakore: iti te tairongo. Ko te nuinga o nga mea whaihua he pukoro muka whatu kore-mahi.
