Fresnel maka aniani mai beacons e likeʻole mau

I ka hala, i ke kokoke loa i kahi a hiki i kaʻaoʻao no ka luina i ka noho pilikia loa hapa o ko lākou heleʻana. Ma muli o ka adverse ino ana a ili Hawaiian pali hiki i ka wreck. Hoopakele luina Lighthouse pono navigational 'ole o ia manawa. No kekahi manawa lōʻihi ma luna o ko lākou mau poʻo pono wahie i nā ahi, ma hope ke kukui ua kerosene kukui a uila hoomaka ae la e e hoʻohana. Ma ka XIX kenekulia, malamalama, ola-olaʻi, ka mea lilo he Fresnel maka aniani i mea malamalama o ka lighthouse ka loa luku ana a me ka hiki, mai kahi mamao.

Ke keʻena eiiieaena maka aniani i hanaia e Augustin Fresnel, Palani physicist, i hoʻokumu o ka kumumanaʻo nalu o ka malamalama. Fresnel maka aniani haku o ka uuku mānoanoa o kanaka concentric apo e pili ana i kekahi i kekahi, a ho okumu i ka paukūʻolokaʻa me ka malamalama kahi loko. Nā apo i ke kinona o ka prisms. Kēlā me kēia o nā apo 'ohi i malamalama i loko o kekahi wahi paiki laau nui no laua na kukuna diverging mai o ka waena. E kaʻapuni i ka paukūʻolokaʻa puni ka malamalama kumu malamalama kedera e holo ana i ka moana lipolipo. Kala like 'ole kaola, i ko lakou helu, i ka manawa wā mawaena ma waena o ia hoolilo i ka hana hanana a lima beacon. A hōʻuluʻulu manaʻo o nā 'ano o nā Lighthouse likeʻole i ma luna o nā moku, a me ia mea no kona mau luina aʻo i ka lighthouse ma ke alo o ia.

Fresnel maka aniani hoʻouka kekahi ma Lighthouse, mea nui i koe i loko o iai? Oaiaaiea ia me ka ikaika malamalama kumu. Mau luna 'ahupapa maka aniani i ka mea i hiki, e hoomahuahua i ka lehulehu o ka pinepine' i ka 80 000 CD. A hiki i ka hana mea hou i hana muaʻole o Fresnel pulakaumaka malamalama a me ke kukui e aa poe hewa ke wale waiho i ka li ili i loko o ka pulakaumaka converging maka aniani i lawa ka nui anawaena a me ka concave aniani. No keia mea ua pono integral'ōnohi hehee ai o ka nui nui, i mea ma lalo o ka aoao o kona umekaumaha iho ke poha. No laila, hana ōlaʻi i o concave aniani keleawe, ka pulakaumaka o kela mea keia mea o lakou, ua he hookahi ipukukui. Keia olelo hooholo i ke koikoi.

Ke ahupapa Fresnel maka aniani kokua loaʻa, a mahuahua nui malamalama pinepine ', i ka lehulehu i loko o ka haawi mai ai ka ao ao. I kaʻaha kanaka o ke kanaka'ōnohi hehee wale, aole ia e noonoo i ka malamalama, a ua hana mai ia i ka malamalama, revolving a puni houʻia ana ma nāʻaoʻao ma ka malamalama kahi o mau pinepine '.

Mai ka Fresnel 'ole i unsurpassed oaoieei-mea hoʻohana ole wale no River buoys a me beacons. Ma ka mua Fresnel maka aniani i ke aniani o kekahi ka hōʻikeʻana kukui, kalepa ae la lakou kukui, kaa headlights, projectors hapa haʻi'ōlelo. A laila, magnifiers i ua hana i loko o ka palapala o ka laina i ka aniani moakaka ea, me ka inconspicuous hoʻopoepoe Groove, kela mea keia mea o ka a i ka'āhihi annular prism, akā, i ka nui ka mea, ua i kaʻohiʻana i ke maka aniani. Ke kūpono maka aniani Ua hoʻohana 'ia me ke kiʻiona aniani no ka nui mea e like me ka pahupaʻiwikiō maka aniani, e pili ana i ka hulu kiʻi.

Over manawa, i ka laulā o ka Fresnel maka aniani i hoomaka nunui. Ua nā kiʻi kūpono 'ana, na kau iho i na mea maalea, e malu nenoai, hoʻomakākiu pono, ikehu concentrator no ka poe Waihona Noʻeau, aniani keleawe i hoʻohana ma telescopes. i ke'ōnohi waiwai o nā aniani kaulona e ia i loko o ke kula o ka likeʻole. No laila, ma ka DNP, na nui loa ka hoʻohua o kiʻekiʻe-ʻenehana wānana pale, ma ke kumu o na maka aniani e Supernova pale. Ma ka hope o wānana pale ua hoʻohana 'ole wale i ka Fresnel maka aniani, akā,' ē aʻe'ōnohi loea, a leie aku e loaa hanana 'ia' ana.

Ke kaumaha ma muli o ka palapala noi, me ka maka aniani ke i he okoa anawaena, okoa type. Aia he mau ke ano o nā aniani kaulona: ke apo, a kāʻei. First hana e kauoha i ke kahe o ka malamalama na kukuna o ka e like me mamua. Hoʻopoepoe nā aniani kaulona i ua hoʻohana ma manuale hana me ka uuku lāliʻi, pau ka maʻamau kiʻiona aniani.

Fresnel maka aniani paha ia he maikaʻi (kaʻohiʻana) a me ka io (diverging). Tewetewe io maka aniani me ka pōkole mea nui wahi me ka nui loa maoli ke kahua o ka Hawaii. I ua kapaʻiaʻo ia me ka Fresnel maka aniani i? Iaie?. O ka ho onui ana o ka, mākaʻi ihola iā huina, i mea hoakaka, e leie aku oe i ka ike i nā pilikia i ka poe ma ka lalo o ke kaʻa,ʻaʻole i loko o ka mahinaʻai o ka Hawaii o kaʻaoʻao aniani, a rearview aniani.
