I te mea kei te whakawehihia te kounga o te wai e ngā wero taiao o te ao, kei te piki haere te hiahia mō ngā otinga aroturuki whai hua. Ka puta ake ngā hangarau pūoko whakaahua hei taputapu aromatawai kounga wai tika me te wā tūturu, e tuku ana i te aro nui me te whiriwhiri i roto i ngā taiao wai kanorau.
Ngā Mātāpono o ngā Hangarau Pūoko Whakaahua
Ka whakamahia e ngā hangarau pūoko whakaahua ngā taunekeneke taketake o te māramatanga-matū, pērā i te tuku me te whakaata, hei tautuhi i ngā mea e pupuri ana, i ngā tohu kounga wai matua rānei pērā i ngā totoka whakatārewatia katoa (TSS).
Ka whakamahia e ēnei pūoko ngā pūtake mārama pēnei i ngā LED me ngā taiaho hei whakamārama i te wai, ka pā te rahi me te hanganga o ngā poke ki te taunekeneke o te mārama, ka puta ai ngā huringa o te kaha o te mārama, o te roanga ngaru rānei.
Kātahi ka tuhia ēnei panoni mā te whakamahi i ngā tikanga kimi, tae atu ki ngā photodiode, ngā phototransistors, ngā taputapu hono-utu (CCD) rānei, e ine ana i te kaha o te mārama i muri i te taunekeneke ki ngā poke. He maha ngā wā ka whakamahia ngā muka whatu hei arahi i te mārama ki te tauira wai, mai i te tauira wai hoki, kia taea ai te kite mamao, te kite tohatoha rānei.
Haunga te ine i te tuku me te whakaata o te mārama, ka whakamahia e ētahi pūoko whakaahua ngā āhuatanga whatu motuhake hei kite i ngā poke. Hei tauira, ka whakaohohia e ngā pūoko hihi-ā-rangi ngā ngota hihi-ā-rangi i roto i te wai ki te mārama o tētahi roangaru motuhake, ā, ka ine i te kaha o te hihi-ā-rangi e tukuna ana, ka taea te hono atu ki te kukū o ngā poke motuhake.
I tetahi atu taha, ka aroturukihia e ngā pūoko oro plasmon mata (SPR) ngā rerekētanga o te taupū whakaata o te mata whakarewa e puta mai ana i te herea o ngā ngota ūnga, ka whakaratohia he tikanga kimi kore-tapanga me te wā-tūturu.
Ka taea e mātou te whakarato i ngā pūoko kounga wai me ngā tawhā rerekē mō ngā momo horopaki tono, penei:
