Ngā tawhā āhuatanga mahi nui o te pūnaha taiaho

1. Roangaru (waeine: nm ki μm)

Teroangaru taiahoe tohu ana i te roangaru o te ngaru hikohiko e haria ana e te taiaho. Ki te whakatauritea ki ētahi atu momo māramatanga, he āhuatanga nui orēserihe kotahi te tae, arā, he tino parakore tōna roangaru, ā, kotahi anake te auau kua tautuhia pai.

Ko te rerekētanga i waenga i ngā roangaru rerekē o te taiaho:

Ko te roangaru o te taiaho whero kei waenganui i te 630nm-680nm, ā, he whero te mārama e tukuna ana, ā, koinei hoki te taiaho tino noa (e whakamahia ana i te nuinga o te wā i roto i te mara o te rama whāngai hauora, me ētahi atu);

Ko te roanga ngaru o te taiaho matomato he 532nm te nuinga, (e whakamahia ana i te nuinga o te wā i roto i te mara o te horapa taiaho, me ētahi atu);

Ko te roangaru o te taiaho kikorangi kei waenganui i te 400nm-500nm (e whakamahia ana mō te pokanga taiaho);

Te taiaho UV i waenga i te 350nm-400nm (e whakamahia ana i roto i te koiora);

Ko te reihi whero te mea tino motuhake, e ai ki te whānuitanga o ngā roangaru me te mara tono, ko te roangaru reihi whero te nuinga o te wā kei roto i te whānuitanga o te 700nm-1mm. Ka taea te wehewehe i te roopu whero ki ngā roopu iti e toru: te whero tata (NIR), te whero waenga (MIR) me te whero tawhiti (FIR). Ko te whānuitanga o ngā roangaru whero tata kei waenganui i te 750nm-1400nm, e whakamahia whānuitia ana i roto i te whakawhitiwhiti muka whatu, te whakaahua koiora me ngā taputapu tirohanga pō whero.

2. Mana me te pūngao (wāhanga: W, J rānei)

Mana taiahoe whakamahia ana hei whakaahua i te putanga mana whatu o te taiaho ngaru tonu (CW) te mana toharite rānei o te taiaho pāorooro. Hei tāpiri, ko ngā taiaho pāorooro e tohuhia ana e te mea he ōrite te kaha pāorooro o tō rātou kaha pāorooro ki te mana toharite, ā, he ōrite whakamuri ki te tere whakahokinga o te pāorooro, ā, ko ngā taiaho he kaha me te kaha teitei ake ka whakaputa i te wera para nui ake.

He āhua hihi Gaussian te nuinga o ngā hihi laser, nō reira ko te hihi me te rere o te hihi he teitei rawa atu i runga i te tuaka whatu o te laser, ā, ka heke iho i te pikinga ake o te rerekētanga mai i te tuaka whatu. Ko ētahi atu laser he āhua hihi papatahi, he rerekē ki ngā hihi Gaussian, he āhua hihi pumau tonu puta noa i te wāhanga whakawhiti o te hihi laser, ā, he tere te heke o te kaha. Nō reira, kāore he hihi tihi o ngā laser papatahi. Ko te kaha tihi o te hihi Gaussian he rua te nui o te kaha o te hihi papatahi me te kaha toharite ōrite.

3. Te roa o te pā (waeine: fs ki ms)

Ko te roa o te pā o te taiaho (arā, te whānui o te pā) ko te wā e pau ana kia tae atu te taiaho ki te haurua o te mana whatu mōrahi (FWHM).

 

4. Te tere o te tukurua (waeine: Hz ki MHz)

Ko te tere o te tāruarua o tētahireera pāorooro(arā, ko te tere whakahokinga o te pāorooro) e whakaahua ana i te maha o ngā pāorooro e tukuna ana i ia hekona, arā, ko te taurite o te mokowā pāorooro raupapa wā. He rite whakamuri te tere whakahokinga ki te kaha pāorooro, ā, he rite ki te mana toharite. Ahakoa te tikanga ka whakawhirinaki te tere whakahokinga ki te reo whakanui taiaho, i roto i te nuinga o ngā wā, ka taea te whakarerekē i te tere whakahokinga. Ko te tere whakahokinga teitei ake ka hua ake he wā whakangā wera poto ake mō te mata me te arotahi whakamutunga o te huānga whatu taiaho, ā, ka tere ake te wera o te rauemi.

5. Te rerekētanga (waeine noa: mrad)

Ahakoa e whakaarohia whānuitia ana ngā hihi laser he mea e whakakotahi ana, he nui tonu te rerekētanga kei roto, e whakaahua ana i te whānuitanga o te rerekētanga o te hihi i runga i te tawhiti e piki haere ana mai i te hope o te hihi laser nā te rerekētanga. I roto i ngā tono me ngā tawhiti mahi roa, pērā i ngā pūnaha liDAR, ina rau mita te tawhiti o ngā mea mai i te pūnaha laser, ka noho te rerekētanga hei raruraru tino nui.

6. Rahi o te ira (waeine: μm)

Ko te rahi o te ira o te hihi laser arotahi e whakaahua ana i te whānui o te hihi i te pūwāhi arotahi o te pūnaha arotahi arotahi. I roto i te maha o ngā tono, pērā i te tukatuka rauemi me te pokanga hauora, ko te whāinga he whakaiti i te rahi o te ira. Mā tēnei ka whakanui ake i te kaha o te kaha, ā, ka taea te hanga i ngā āhuatanga tino pai. He maha ngā wā ka whakamahia ngā arotahi porowhita hei utu mō ngā arotahi porowhita tuku iho hei whakaiti i ngā hapa porowhita me te whakaputa i te rahi o te ira arotahi iti ake.

7. Tawhiti mahi (waeine: μm ki m)

Ko te tawhiti whakahaere o tētahi pūnaha taiaho e tautuhia ana ko te tawhiti ā-tinana mai i te huānga whatu whakamutunga (he arotahi arotahi te nuinga) ki te mea, ki te mata rānei e arotahihia ana e te taiaho. Ko ētahi tono, pērā i ngā taiaho hauora, e whai ana ki te whakaiti i te tawhiti whakahaere, ko ētahi atu, pērā i te pūoko mamao, e whai ana ki te whakanui ake i te whānuitanga o te tawhiti whakahaere.
