Te hangarau kimi hiko hou rawa atu (Pūoko whakaahua horonga) : He upoko hou mō te whakaatu i ngā tohu mārama ngoikore
I roto i te rangahau pūtaiao, ko te kimi tika i ngā tohu mārama ngoikore te mea nui ki te whakatuwhera i ngā mara pūtaiao maha. Nō nā tata nei, kua kawea mai e tētahi whakatutukitanga rangahau pūtaiao hou ngā huringa nui ki te kimi i ngā tohu mārama ngoikore. Ko tepūoko whakaahua horongaKo te raupapa i whakawhanakehia e tētahi rōpū rangahau pūtaiao rongonui i Haina, me ōna mahi ahurei me ngā painga, ka whakatuwhera i tētahi upoko hou mō te kimi tohu mārama ngoikore.
Te horonga o te hukarerepūoko whakaahuangā hua raupapa, e ai ki te mātāpono whakanui horonga oAPD, ko te whakanui he 10 ki te 100 ngā wā i te pūoko hohonu PIN noa, he tino aro, he iti te haruru, he pai te mahi kimi me ētahi atu painga nui. Mā te putanga mai o tēnei raupapa hua ka āwhina i ngā kairangahau ki te kimi me te tātari i ngā tohu mārama ngoikore, ā, ka whakatairanga anō i te hohonutanga o te rangahau pūtaiao.
Ko ngā āhuatanga matua o tēnei raupapa hua ko te iti o te haruru, te nui o te whiwhinga me te muka whatu, ngā kōwhiringa hononga ā-wāhi. Ko te tikanga, ahakoa he taiao taiwhanga, he taiao matatini o waho rānei, ka taea e te hua te whakatutuki i te kitenga tohu whatu tika, me te whakarato tautoko raraunga pono mō ngā kairangahau. Ehara i te mea ka whakapai ake tēnei hangarau auaha i te whai huatanga o te kitenga o ngā tohu whatu, engari ka whakaitihia hoki te haruru e puta ana i roto i te tukanga kitenga, ā, ka whakapai ake i te tika o te kitenga.
Ina koa, ko te whānuitanga o ngā hihi urupare e kapi ana i te 300-1100nm me te 800-1700nm, me ngā whānui 3dB tae atu ki te 200MHz, 500MHz, 1GHz me te 10GHz. Mā ēnei whakatakotoranga me ngā tawhā kanorau ka taea e te hua te urutau ki ngā hiahia rangahau pūtaiao rerekē, me te whānuitanga o ngā tono, tae atu ki te kimi tohu whatu ngoikore, te kimi tohu pao whatu tere-tiketike, me te whakawhitiwhiti kōrero matū.
He mea tika kia whakahuatia kei roto i te hua he pūoro whakaahua āwhata, he ara iahiko whakanui haruru iti, he ara iahiko whakanui APD, ā, ko te roangaru kitenga o te raupapa hua katoa e kapi ana i te 300nm-1700nm. Mā tēnei hoahoa ka taea e te hua te whakatutuki i te kitenga tairongo teitei, engari ka whakaitihia hoki te haruru, ka whakapai ake i te tika o te kitenga. Hei tāpiri, mā ngā āhuatanga whiriwhiri o te muka whatu me te hononga ā-wāhi ka taea e te hua te whakatutuki i te kitenga tohu tika i roto i ngā taiao uaua.
I roto i te poto, ko te whanaketanga o tēnei horongapūoko hiko whakaahuaHe tino angitu nui tēnei raupapa i roto i te hangarau kimi hiko. Mā te putanga mai o tēnei hua ka taea te kimi i ngā tohu mārama ngoikore puta noa i te ao. E tumanako ana mātou ka nui ake te mahi a tēnei hua i roto i ngā rangahau pūtaiao a meake nei, ka whakatairanga i te ahunga whakamua o te pūtaiao, ā, ka pai ake te mahi ki te whanaketanga o te hapori tangata.
