Kupu Whakataki kiPūoko Whakaahua Taurite(Kaitirotiro Taurite Optoelectronic)
E ai ki te tikanga hononga whatu, ka taea te wehewehe i te Pūoko Whakaahua Taurite ki te momo hononga muka whatu me te momo hononga whatu ā-wāhi. I roto, e rua ngā photodiode tino ōrite, he waeine porowhita whakakaha whakawhiti-haruru iti, he whānui teitei, me te waeine hiko haruru tino iti. He āhuatanga ōna o te ōwehenga whakakore aratau noa teitei, te haruru tino iti, me te whānui teitei, ā, he whānui whānui te whakamahinga i roto i te ao whakawhitiwhiti whatu honohono. Kua noho hei wāhi rangahau mō ngā umanga me ngā whare wānanga i roto i ngā whenua rerekē i ngā tau tata nei.
Te kaupapa mahi o te Pūoko Whakaahua Taurite (Pūoko Taurite Optoelectronic)
E rua ngā photodiode e whakamahia ana e te Pūoko Whakaahua Taurite i roto i te āhua whakamuri hei waeine whiwhi mārama. Ina whiwhi tohu mārama, ka tangohia te iahiko whakaahua i hangaia e ngā photodiode e rua ka honoa ki te whakakaha whakawhiti-ātete hei huri i te tohu iahiko hei tohu ngaohiko hei putanga. Mā te whakamahi i te hanganga whakaiti-ā-unoa ka taea te pehi i te tohu aratau noa e whakaurua mai ana e te iahiko mārama me te pōuri o te oscillator ā-rohe, ka whakanui ake i te tohu aratau rerekē, ā, ki tētahi taumata ka whakapai ake i te kaha ki te kite i ngā tohu mārama ngoikore.
Ngā Painga: Ka taea e te ōwehenga whakakore aratau noa teitei, te tairongo teitei, me te whānui o te whānuitanga kitea teitei te whakatutuki i ngā āhuatanga tono maha.
Ngā Huakore: He iti te mana whatu kua mātotoru, he pai anake mō te kite mārama ngoikore, me whakapai ake te whakaurunga.

Ngā tawhā mahi o te Pūoko Whakaahua Taurite (OptoelectronicPūoko Taurite)
1. Te aro atu
Ko te aro-ā-tinana e pā ana ki te whai huatanga o te photodiode ki te huri i ngā tohu mārama ki te iahiko whakaahua, arā, te ōwehenga o te iahiko whakaahua ki te mana o te mārama. Mā te whiriwhiri i tētahi photodiode he nui ake te aro-ā-tinana ka taea te whakapai ake i te aro o te Balance Photodetector.
Ko te aro-ā-tinana e pā ana ki te whai huatanga o te photodiode ki te huri i ngā tohu mārama ki te iahiko whakaahua, arā, te ōwehenga o te iahiko whakaahua ki te mana o te mārama. Mā te whiriwhiri i tētahi photodiode he nui ake te aro-ā-tinana ka taea te whakapai ake i te aro o te Balance Photodetector.
2. Whānuitanga o te aratuku
Ko te whānui o te ira e tohu ana i te auau tohu e heke ai te kaha o te tohu putanga o te Pūoko Whakaahua Taurite mā te -3dB, ā, e pā ana ki te kaha pirinoa o te photodiode, te rahi o te transimpedance, me te hua whānui o te whakanui o te whakakaha mahi.
3. Ōwehenga whakakorenga aratau noa
Ka whakamahia te ōwehenga whakakorenga aratau noa hei ine i te nui o te pehitanga o ngā tohu aratau noa e ngā pūoko taurite, ā, ko te iti rawa o te whakakorenga aratau noa e hiahiatia ana e ngā hua arumoni he 25dB.
4.NEP
Mana Ōrite Haruru: Ko te mana tohu tāuru e hiahiatia ana i te ōwehenga tohu-ki-haruru o te 1, he tawhā nui tēnei mō te ine i te mahi haruru o tētahi pūnaha. Ko ngā wāhanga matua o te haruru pūoko taurite ko te haruru marara whatu me te haruru hiko.
Te Whakamahinga o te Pūoko Whakaahua Taurite (Pūoko Taurite Optoelectronic)
I ngā tau tata nei, kua whānuitia te whakamahinga o te Balance Photodetector i roto i ngā mara pēnei i te radar hau taiaho, te ine wiri taiaho, te pūoko muka whatu, te pūoko mārama ngoikore, te pūoko hihi, te pūoko hau, me ētahi atu. Ko te rangahau mō te tere teitei, te whānui whānui teitei, te haruru iti, te ōwehenga whakakore aratau noa teitei, me te aro nui o ngā pūoko taurite kua puta he whanaketanga hou, ā, kei te whanake haere ki te whakaurunga teitei me te iti o te whakamahinga hiko hei whakatutuki i ngā horopaki tono rerekē.
