Te Mārama ki te Putanga OCT/Pulse

1. Whakamāramatanga me te Ariā Taketake

Putanga OCT

• Ko te hononga whatu, e mōhiotia ana ko te opto-isolator, kei te ngākau o te putanga OCT. Kei roto i tēnei ko te diode emitting light infrared (LED) me te phototransistor. Ina tukuna he tohu hiko ki te taha whakauru o te hononga whatu, ka tukuna e te LED te mārama infrared. Kātahi ka pā tēnei mārama ki te phototransistor i te taha putanga. Ka rerekē te kawe hiko o te phototransistor hei whakautu ki te kaha o te mārama e pā mai ana. I roto i te horopaki o te putanga OCT, ka whakamahia te putanga hiko mai i te phototransistor hei kawe i ngā mōhiohio. Ka taea tēnei putanga te noho hei tohu matihiko, he teitei, he iti rānei, i runga i te mea kei te mārama te LED, kāore rānei. Mā te whakamahinga o te hononga whatu ka wehea te hiko i waenga i ngā ara iahiko whakauru me te putanga. He mea tino nui tēnei wehe i roto i ngā tono kei reira pea he rerekētanga ngaohiko teitei, he haruru hiko rānei i te taha whakauru ka taea te whakararuraru, te kino rānei i ngā hiko taha putanga tairongo. Hei tauira, i roto i te pūnaha tohatoha hiko, kei reira ngā tohu hiko ngaohiko teitei e aroturukitia ana, ka taea e te putanga OCT te whakawhiti haumaru i ngā mōhiohio mō te āhua, tengā inengao ēnei ara iahiko ngaohiko teitei ki tētahi pūnaha whakahaere, aroturuki rānei ngaohiko iti, me te kore he mōrearea o te pokanoa hiko, o ngā ara iahiko poto rānei.

Putanga Pāta

• Ko te putanga pāoro e pā ana ki te whakaputanga o tētahi raupapa o ngā pāoro hiko motuhake. Ko te pāoro he huringa poto-roa i roto i te taumata tohu hiko, mai i te āhua iti ki te āhua teitei, kātahi ka hoki ki te āhua iti. Ko ngā āhuatanga o ēnei pāoro, pērā i tō rātou auau (te maha o ngā pāoro mō ia wā), te whānui (te roanga o te wāhanga āhua teitei o te pāoro), me te kaha, ka kawe i ngā mōhiohio. I roto i te maha o ngā taputapu ine, pērā i ngā mita rere me ngā mita pūngao, ka hurihia te rahinga e inehia ana hei tohu pāoro e rite ana. Hei tauira, i roto i te mita rere wai, ko ia rahinga wai e haere ana i roto i te mita ka puta he pāoro hiko kotahi. Mā te tatau i te maha o ēnei pāoro i roto i tētahi wā motuhake, ka taea te whakatau i te tapeke o te rere wai. Ko te auau o ngā pāoro he rite tonu ki te tere rere, ā, ko te tere rere teitei ake ka hua ake he auau pāoro teitei ake.

2. Ngā Mātāpono Mahi

Te Whakaputa Pūoro e Hangaia ana e te Oketopa

• I roto i ētahi pūnaha, ka whakamahia te OCT hei whakaputa i te putanga pā. Hei tauira, i roto i tētahi hononga whakawhitiwhiti matihiko i waenga i ngā pūnaha iti e rua e wehea ana e te hiko, ka tukuna pea e tētahi pūmana iti i te taha tuku he raupapa tohu matihiko. Ka whakamahia ēnei tohu hei taraiwa i te LED i roto i te hononga whatu. I te wā e huri ana te pūmana iti i te tohu i waenga i ngā āhua teitei me te iti, ka tahuri, ka whakaweto te LED. Kātahi ka whakaputa te phototransistor i te taha putanga i tētahi raupapa pā e rite ana. Mā te wehenga hiko e whakaratohia ana e te OCT ka whakarite kia kore tetahi haruru hiko, tetahi whakawhiti ngaohiko rānei i runga i te ara iahiko taha tuku e pā ki te ara iahiko taha whiwhi. He tino whai hua tēnei i roto i ngā taiao he nui te pokanoa hikohiko, pērā i ngā wheketere ahumahi kei reira ngā motuka nui me ētahi atu taputapu hiko e whakahaerehia ana.

Te Whakaputa Pāpāho mai i ngā Pūoko

• I roto i ngā tono e hangai ana ki te pūoko, ko te tukanga whakaputa i te putanga pāoro e pā ana ki te rahinga ā-tinana e rongohia ana. Hei tauira, tangohia he pūoko tango aukume e whakamahia ana hei ine i te tere hurihuri o te rakau. Kua hangaia te pūoko hei kite i te haerenga o ngā huānga aukume (pēnei i ngā niho i runga i te taputapu e piri ana ki te rakau). I ia wā ka haere tetahi huānga aukume i te pūoko, ka puta he huringa ki te putanga o te pūoko. Kātahi ka whakatikatikaina tēnei huringa, ka hangaia hei pāoro. Ko te auau o ēnei pāoro e pā tika ana ki te tere hurihuri o te rakau. Mena ka tere ake te hurihuri o te rakau, ka nui ake ngā huānga aukume e haere ana i te pūoko i ia wae wā, ka hua ake he auau pāoro teitei ake. Kātahi ka taea te tuku i tēnei putanga pāoro ki tētahi pūmana iti, ki tētahi atu taputapu whakahaere rānei hei tukatuka atu, pērā i te tatau i te tere hurihuri me te whakaatu ki runga i te aroturuki.

3. Ngā tono

Aunoatanga Ahumahi

• I roto i ngā pūnaha aunoatanga ahumahi, he whānui te whakamahinga o te putanga OCT/pā. Hei tauira, i roto i te pūnaha whitiki kawe, ka taea te whakamahi i ngā pūoko tata me te putanga pā hei kite i te aroaro me te nekehanga o ngā mea i runga i te whitiki. Ia wā ka pā atu tētahi mea ki tētahi pūoko, ka puta he pā. Ka taea te tatau i ēnei pā e tētahi kaiwhakahaere arorau hōtaka (PLC) hei aroturuki i te maha o ngā taonga e haria ana. Ka whakamahia te putanga OCT ina hiahia ēnei pūoko ki te kōrero ki te PLC me te pupuri tonu i te wehenga hiko, me te tiaki i ngā ara iahiko PLC tairongo mai i te haruru hiko pea, i ngā pikinga ngaohiko rānei i roto i te taiao ahumahi.

Ine Pūngao

• I roto i ngā mita hiko me te hau, he āhuatanga noa te putanga pātītī. Mō te mita hiko, ka inehia te whakapaunga pūngao i runga i te maha o ngā watt - haora e whakamahia ana. Ka hurihia e te ara iahiko ā-roto o te mita te pūngao hiko i inehia hei raupapa pātītī. Ko te nui ake o te pūngao e pau ana, ko te nui ake o ngā pātītī ka puta. Ka taea te tuku i ēnei pātītī ki tētahi kairūri raraunga, ki tētahi pūnaha whatunga atamai rānei mō te aroturuki mamao me ngā kaupapa nama. Mā te whakamahinga o te putanga pātītī ka māmā ake te tukanga whakawhitiwhiti kōrero, ā, ka taea te whakauru ngāwari ki ētahi atu.ngā pūnaha whakahaere pūngao.

Ngā taputapu me te ine

• I roto i ngā taputapu ine maha, pērā i ngā oscilloscope me ngā kaute auau, ka taea te whakamahi i te putanga OCT/pānga mō te whakatikatika me te whakawhiti tohu. Hei tauira, ka taea e te pūtake whakatikatika te whakaputa i ngā tohu pānga tika me ngā auau me ngā kaha e mōhiotia ana. Ka taea te tuku i ēnei pānga ki te taputapu e whakatikatikaina ana mā te atanga e hangai ana ki te OCT hei whakarite i te mahi ine tika. I roto i te kaute auau, ka tatauhia, ka tātarihia hoki te tohu whakauru, he tereina pānga pea mai i te pūoko, i te hononga whakawhitiwhiti kōrero rānei, hei whakatau i te auau o te tohu.
