Ko te mahi a ngā taura muka whatu mā te tuku raraunga hei pāorooro mārama mā roto i te aho karāhe, i te muka kirihou rānei. Anei tētahi tirohanga whānui mō tā rātou mahi:

Te Tuku Mārama: He uho te taura muka whatu, arā, he aho karāhe angiangi, he aho kirihou rānei e haere ai te mārama, e karapotia ana e te paparanga whakakikorua e whakaata ana i te mārama ki roto i te uho, e ārai ana i te ngaronga o te tohu. He rerekē ngā taupū whakaata o te uho me te whakakikorua, e āhei ai te whakaata katoa o roto.

Pūtake Mārama: Kei tetahi pito o te taura muka whatu he pūtake mārama, he taiaho, he LED rānei (Light Emitting Diode). Mā tēnei pūtake mārama ka whakaputa i ngā tohu mārama ka tukuna ki roto i te taura muka whatu.

Te Whakatipu: Ka uru ngā tohu mārama ki te pūtake o te taura muka whatu, ka haere i tōna roanga mā te tukanga e kiia nei ko te whakaata ā-roto katoa. Ko te tikanga, ka peke te mārama mai i te paparanga whakakikorua, ka whakaata tonu ki roto i te pūtake.

Whiwhinga Tohu: Kei te pito kē o te taura muka whatu, kei reira he kaiwhiwhi e kite ana i ngā tohu mārama. Kei roto i tēnei kaiwhiwhi he photodiode, he photodetector rānei e huri ana i ngā tohu mārama hei tohu hiko.

Te Tuku Raraunga: Kātahi ka tukatukahia ngā tohu hiko e whiwhihia ana mai i te photodiode, ka hurihia anō hei raraunga mamati, ka taea te mārama mā ngā taputapu hiko pēnei i ngā rorohiko, ngā pouara, ngā waea rānei.

Āe! Kei raro nei te Hanganga o te Kauwhata Muka Whatu:

Matua: Ko te uho te wāhanga pokapū o te muka whatu e haere ai te mārama. He mea hanga i te karāhe, i te kirihou rānei, ā, he teitei ake te taupū whakaata i te uhi, e āhei ai te mārama ki te ārahi i te mārama i te muka mā te whakaata ā-roto katoa.

Whakatakotoranga: Ka karapotia te uho e te uhi, ā, he mea hanga ki tētahi rauemi he iti ake te taupū whakaata i te uho. Ko tōna kaupapa he whakaata i te mārama ki roto i te uho, hei ārai i te ngaronga o te tohu, me te pupuri i te pumau o te tohu mārama i a ia e haere ana i roto i te muka.

Paninga Pūwero: I roto i ngā taura muka whatu mahi, he maha ngā wā he paparanga anō e kiia ana he paninga ārai e karapoti ana i te uhi. Ka tiakina e tēnei paninga te muka mai i ngā āhuatanga o waho pērā i te makuku, te kino ā-tinana, me ngā huringa pāmahana.

E whakaatu ana tēnei hoahoa taketake i te hanganga taketake o te muka whatu, engari i roto i ngā mahi whaihua, ka honoa ngā muka whatu ki roto i ngā uhi tiaki hei hanga taura muka whatu e whakamahia ana mō te whakawhitiwhiti kōrero, te tuku ipurangi, me ētahi atu mahi.

He maha ngā painga o ngā taura muka whatu i ngā taura parahi tuku iho, tae atu ki te whānui ake o te hononga, te tere ake o te tuku raraunga, te ātete ki te pokanoa hikohiko, me te haumarutanga nui ake nā te uaua o te uru atu ki te tohu me te kore e whakararuraru. Nā ēnei āhuatanga ka waiho ngā taura muka whatu hei whiringa pai mō ngā whakawhitiwhiti kōrero tawhiti me ngā hononga ipurangi tere-tiketike.
