Fresnel arotahi i ramaroa ki ngā wāhi rongorau

I roto i te mua, te huarahi ki te rohe hoki heramana ko te wahi tino mōrearea o ratou ara. Nā ki ngā āhuatanga huarere aituä paea pari takutai ranei i taea e meinga he waka. heramana whakaorangia Lighthouses pai hanganga whakatere o taua wa. Hoki te wa roa i runga i o ratou kouru kuhu noa nga ahi, i muri mai te marama puna rama karahīni noa timata hiko ki te whakamahi. I roto i te XIX rau, marama, te ora-ora, riro te reira i te arotahi Fresnel e te Tūrongo tino me kitea i tawhiti hanga marama o te rama.

I hanga arotahi matatini Wae e Augustin Fresnel, ahupūngao French, kaiwhakarewa o te ariā poipoi o te marama. arotahi Fresnel titoa o te matotoru iti o takitahi mowhiti concentric pātata ki tahi i te tahi, me te hanga i te rango ki te puna marama i roto. Ko te mowhiti i te āhua o poro. Ia o nga mowhiti kohikohi marama i roto i te kurupae kuiti o hihi whakarara te faaatea i te pokapū. Na roto i te tītaka te puoto a tawhio noa te kurupae pūtake marama marama whakawhānui ki te pae. kurupae Tae, ratou tokomaha, te wā wa i waenganui i a ratou kėia he mori ringaringa ahurei motuhake. He whakarāpopototanga o te āhuatanga o te ngā tiiramaroa i runga kaipuke poari, a ko reira hoki ako ona heramana he whare rama i roto i te mua o ratou.

Fresnel arotahi tāuta i roto i tiiramaroa, ko te taahiraa nui i roto i te taputapu ratou ki ngā puna te marama kaha. hanga enei arotahi hiato matatini reira taea ki te whakapiki ake i te kukū o te kaha ki runga, ki te 80 000 kōpae. Tae noa te tenenga o te marama arotahi Fresnel rama mura muka ranei i taea e anake whakatakoto te kasa i roto i te arotahi ūngutu tirohanga diameter feunga nui te whakaata kōpapa ranei. Hoki tenei whakaaro i tika huānga whatu wāhi o te rahi nui, i te mea i raro i te mana o ona ake mahara taea pakaru. Na reira, te whakamahi i pinepine o whakaata kōpapa, ko te arotahi o ia o ratou he rama kotahi. I fiemālie tenei whakatau.

Ua tauturu te arotahi Fresnel hiato whakatutuki kaha marama nui haere, te kukū i roto i te ahunga i homai. E kore e te whakaminenga o ngā āhuatanga whatu takitahi whakaata marama, a ka mahi ki runga ki te marama, whakakopa tawhio anaana i roto i ngā tohutohu katoa i te puna marama o te kaha tonu.

Mai te hanganga Fresnel he pūrere hangarau â whakamahia kore anake hoki te awa ua faaoaoa ia me ngā ramaroa. I roto i te arotahi Fresnel tuatahi i hanga o te karaihe o rama rerekē kē, rama waka, tupohehia waka, pūwhiti wahi kauhau. Na kua oti magnifiers hanga i roto i te puka o ngā rārangi i hanga o kirihou mārama, me ngā awaawa porohita inconspicuous, ia o nei ko te poro annular iti, engari i roto i te whānui i ratou i te arotahi kohikohi. whakamahia te arotahi hua te rite he mōwhiti mō ahanoa nui pērā i te arotahi kāmera, te hanga i tētahi whakapakoko kōaro.

Neke atu i te wa, kua whakawhānuitia te hōkai o te arotahi Fresnel tino. Kei roto te reira i te whanaketanga whakaahua, ngā whakaaro rama, ngā pūnaha haumaru, taputapu tirotiro, pūngao concentrator hoki kaikohikohi solar, whakaata e whakamahia ana i roto i whātata. Kei te whakamahia hoki te āhuatanga optical o arotahi i roto i te mara o te rongorau. Na, i te DNP, te kaihanga nui rawa o ngā mata ngä nui-tech, i runga i te pūtake o te tirohanga he mata supernova. I roto i te ngä mata muri te whakamahia ki te arotahi Fresnel, engari ētahi atu hangarau optical, e taea ana ki te whiwhi te tikanga whakaaturanga ahurei kore anake.

Tei runga i te tono, kia whai i te arotahi te diameter rerekē, rerekē momo. E rua ngā momo o ngā arotahi: te whakakai me whitiki. Tuatahi hanga ki te whakatika i te rere o hihi marama i roto i te ahunga kotahi. Kua arotahi Porohita whakamahia i roto i te mahi ā-ringa ki te kōrero iti, displacing mōwhiti noa. arotahi whitiki ahei o whakawhitihia kurupae marama i roto i tetahi aronga hoatu, kei te whakamahia i roto i te rängai ahumahi.

kia waiho Fresnel arotahi he pai (kohikohi) me tōraro (te faaatea). Polyvinyl arotahi kino ki te pokapū poto tino whakanuia ana te mara o te tirohanga. Kei te mohiotia ia rite te tirohanga waka Fresnel. Ko te roha o te koki mātakitaki, e whakarato ana te reira, taea ai e koe te kite i te mau fifi e te hunga i te raro o te waka, e kore i roto i te mara o te tirohanga o te whakaata taha me te hi'oo te. Ko nui māmā ki te parepare, ka waka tenei arotahi, e kukume te wakatō, a kōaro, faka'ehi'ehi mei tutukinga ki te tākaro tamariki, kararehe ranei ētahi atu taonga.

kua meinga Fresnel arotahi te taputapu multifunctional, takaro tona tenenga he wāhi nui i roto i te mara whanaketanga hangarau.
