Te whakawhitiwhiti kōrero matū:ngā taiaho whānui-rārangi whaiti

Taiaho whānui-rārangi whaitiHe momo taiaho he āhuatanga whatu motuhake, e tohuhia ana e te kaha ki te whakaputa i te hihi taiaho me te whānui raina whatu iti rawa (arā, te whānuitanga whaiti). Ko te whānui raina o te taiaho whānui raina whaiti e pā ana ki te whānui o tōna whānuitanga, e whakaatuhia ana i roto i te whānui i roto i te auau wae, ā, e mōhiotia ana hoki tēnei whānui ko te "whānui raina whānuitanga" ko te "whānui raina" noa rānei. He whānui raina whaiti ngā taiaho whānui raina whaiti, i waenganui i te rau kirohertz (kHz) me te megahertz (MHz) torutoru, he iti ake i te whānui raina whānuitanga o ngā taiaho tikanga.

Te whakarōpūtanga mā te hanganga o te kōhao:

1. Ka wehea ngā taiaho muka āputa rārangi ki te momo whakaata tohatoha Bragg (taiaho DBR) me te momo urupare tohatoha (DFB Laser) e rua ngā hanganga. Ko te taiaho putanga o ngā taiaho e rua he mārama tino piripono me te whānui rārangi whaiti me te haruru iti. Ka taea e te taiaho muka DFB te whakatutuki i te urupare taiaho me terēserite kōwhiringa aratau, kia pai ai te pumau o te auau taiaho putanga, ā, he māmā ake te whiwhi putanga aratau roa kotahi pumau.

2. Ka whakaputahia e ngā taiaho muka mowhiti-kōhao ngā taiaho whānui-whaiti mā te whakauru i ngā tātari roopu-whaiti pērā i ngā kōhao pokanoa Fabry-Perot (FP), te whatanga muka, ngā kōhao mowhiti sagnac rānei ki roto i te kōhao. Heoi, nā te roa o te kōhao, he iti te wā aratau roa, ā, he ngāwari te peke i te aratau i raro i te awe o te taiao, ā, he ngoikore te pumau.

Te tono hua:

1. Pūoko whatu Mā te whakamahi i te taiaho whānui-whaiti hei pūtake mārama pai mō ngā pūoko muka whatu, mā te whakakotahi me ngā pūoko muka whatu, ka taea te whakatutuki i te ine tino tika, tino tairongo. Hei tauira, i roto i ngā pūoko muka whatu pēhanga, pāmahana rānei, mā te pumau o te taiaho whānui-rārangi whaiti ka āwhina i te whakarite i te tika o ngā hua ine.

2. Te ine i ngā hihi āwhata teitei He tino whaiti ngā whānui o ngā hihi āwhata o ngā taiaho whānui-rārangi whaiti, ā, he puna pai ēnei mō ngā ine hihi āwhata teitei-rārangi. Mā te whiriwhiri i te roanga ngaru me te whānui-rārangi tika, ka taea te whakamahi i ngā taiaho whānui-rārangi whaiti mō te tātari hihi āwhata tika me te ine hihi āwhata. Hei tauira, i roto i ngā pūoko hau me te aroturuki taiao, ka taea te whakamahi i ngā taiaho whānui-rārangi whaiti hei whakatutuki i ngā ine tika o te mimiti whatu, te tukunga whatu me ngā hihi āwhata ngota i roto i te hau.

3. He mea nui anō hoki ngā whakamahinga o ngā taiaho muka whānui-rārangi whaiti auau-kotahi a Lidar i roto i ngā pūnaha whāititanga liDAR, taiaho rānei. Mā te whakamahi i te taiaho muka whānui-rārangi whaiti auau-kotahi hei pūtake mārama kimi, me te kimi i te hononga whatu, ka taea te hanga i tētahi liDAR tawhiti (rau kiromita) rānei, he ine whānuitanga rānei. He rite tonu te kaupapa mahi a tēnei mātāpono ki te hangarau OFDR i roto i te muka whatu, nō reira, ehara i te mea he tino teitei te taumira ā-wāhi, engari ka taea hoki te whakanui ake i te tawhiti ine. I roto i tēnei pūnaha, ko te whānui rārangi whāititanga taiaho, ko te roa hononga rānei, te mea e whakatau ana i te whānuitanga ine tawhiti me te tika o te ine, nō reira, ko te pai ake o te hononga o te pūtake mārama, ko te teitei ake o te mahi a te pūnaha katoa.
