Hoʻolauna pōkole no Projection Dome

ʻO ka projection dome kahi ʻenehana hōʻike e puka mai ana e hana ana i nā kiʻi ma luna o ka pale spherical dome ma o nā mea hana projection (hoʻokahi a ʻoi aʻe paha projectors) e hana i kahi kiʻi panoramic 360-degere. He ʻāpana koʻikoʻi ia o nā planetariums a i ʻole nā ​​hale keaka dome.

Hoʻomaka pōkole no ka Optical Planetarium Projector

He mea hana ʻepekema kaulana ka planetarium projector e hoʻohālike ana i nā hana lewa hōkū, ʻike ʻia hoʻi he planetarium hoʻopunipuni. Ma o ke kuhi ʻana o ka mea kani, hōʻike ʻia nā mea lani like ʻole i ʻike ʻia e ka poʻe ma nā lonitu a me nā latitu like ʻole ma ka honua ma ka pale lani hemispherical. ʻO kāna kumu kumu, ʻo ia ka hoʻihoʻi ʻana a me ka hoʻolālā ʻana i ka lani hōkū i haku ʻia me nā kiʻi ʻoniʻoni hōkū optical ma luna o ka pale dome hemispherical ma o ka lens optical e hana i ka lani hoku hana.

Hoʻolauna pōkole no Digital Planetarium Projector

ʻO ka projector planetarium kikohoʻe he ʻano mea hana hōkū ma muli o ka ʻenehana kamepiula. Hoʻokumu ʻia ia me ka ʻōnaehana kamepiula, projector kikohoʻe, ka leo leo a me nā leki iʻa, hiki ke hōʻike i ka neʻe ʻana o nā kino lani a hōʻike i nā kiʻiʻoniʻoni piha i loko o kahi dome semispherical.

Hoʻomaka pōkole no ka Multi-Channel Dome Fusion Digital Astronomical Demonstration System

He ʻōnaehana ʻenehana projection kiʻekiʻe ka ʻōnaehana dome fusion multi-channel. Hoʻohana ʻo ia i nā projectors lehulehu a me ka ʻenehana fusion ʻoihana e hoʻolālā i nā kiʻi mai nā projectors lehulehu ma ka pale spherical, e ʻike pono ana i ka hui ʻana o nā kiʻi he nui ma o ka mea hana kikohoʻe a hana i kahi kiʻi panoramic ʻole.

Hoʻolauna pōkole no Astronomical Dome

ʻO ka observatory kahi hale i hoʻolaʻa ʻia no ka nānā ʻana a me ke aʻo ʻana i nā kino lani. Ma ke ʻano he ʻāpana koʻikoʻi o ka hale kiaʻi, ʻo ka hana nui o ka dome astronomical ka mālama ʻana i ka telescope i loko. He ʻōpuni pōʻai puni ia i hana mau ʻia me nā mea metala paʻa e hōʻoia i kona paʻa a paʻa. Hiki ke hoʻomalu pono ʻia ke ʻano o ka wehe ʻana a pani ʻana o ka dome, e ʻae ana i ka telescope e kuhikuhi i nā wahi like ʻole o ka lewa me ka pale ʻana iā ia mai ka pōʻino i hana ʻia e nā kūlana ʻino.

Hoʻomaka pōkole no ka hana ʻana o ka pepa i hoʻokumu ʻia hyperboloid

ʻO "Hyperboloid formed sheet" ke kumu a me ka mea nui no ka splicing a me ka hui pū ʻana o nā hale spherical nui. No ka mea, loaʻa i ka papa hana hyperbolic nā hiʻohiʻona o nā arcs spherical ma ka ʻaoʻao a me ka vertically, ʻo ka pōʻai i hoʻopili ʻia e kēia ʻano pā he pōʻai maʻamau. ʻO kahi pōʻai i hoʻopili ʻia e nā papa maʻamau ʻaʻole i loaʻa kēia ʻano "hyperbolic" hiki ke lilo i "kahi kokoke".

Hoʻolauna pōkole no Dome Theate

ʻO Dome Theatre, ʻike ʻia hoʻi ʻo "kiʻiʻoniʻoni dome" a i ʻole "kiʻi kiʻiʻoniʻoni", he ʻike ʻike kiʻiʻoniʻoni kūʻokoʻa a weliweli. Hoʻohana ʻo ia i kahi pale metala kani-alohi, i hui pū ʻia me nā mea hana hoʻolālā kikohoʻe hou a hoʻopuni i nā hopena kani, e ʻike ai ka poʻe me he mea lā aia lākou i loko o kahi ʻano dome-like.

Hoʻolauna pōkole no ka Lens Fisheye

ʻO ka lens fisheye he ʻano lens kiʻi ākea ākea me ka lōʻihi o 16mm a i ʻole ka liʻiliʻi. ʻO kona kihi o ka nānā ʻana ua kokoke a i like a ʻoi aku paha ma mua o 180 °. ʻO ka lens mua o kēia ʻano lens he pōkole loa ke anawaena a hoʻopuka i ka parabolic i mua o ka lens. Ua like kona ʻano me nā maka o ka iʻa, no laila ua kapa ʻia ʻo "fisheye lens".

Hoʻolauna pōkole no Ultra Digital Planetarium Projector

Hoʻohana ka Ultra digital planetarium projector i ka ʻenehana lolouila ma ke ʻano he kumu, hoʻololi i nā kiʻi ma o nā ʻāpana hana lolouila a hoʻohana i ka lens fisheye ultra-ākea-ākea e hoʻolālā i nā kiʻi ma luna o kahi dome hemispherical. Loaʻa ka nui o kahi ʻōnaehana kamepiula, 4k projector, nā mea haʻi'ōlelo a me nā leki maka iʻa. Hoʻohana ʻia ia no nā domes a i ʻole tilted domes me ke anawaena o 3 ~ 12m.

Hoʻolauna pōkole no ka pale kau ʻana

Ke hoʻokani nui nei nā projectors i kahi hana koʻikoʻi i nā ʻoliʻoli nui a me nā wahi hōʻikeʻike. ʻO ke kūpaʻa o nā mea hana hoʻolālā i ka wā o ka hoʻohui ʻana o ka projection e hoʻoholo pololei i ka pono o ke kiʻi projection a me ka hopena o ka hōʻike. I ka hapanui o nā hihia, hoʻohana ʻia kahi rack maʻamau (projector bracket) no ka hoʻokō ʻana. ʻO kēia ʻano rack i hoʻopilikino ʻia he pōʻai hana lōʻihi a me ke kumukūʻai kiʻekiʻe, e hoʻonui ai i ka paʻakikī o ke kūkulu ʻana. No laila, i mea e hoʻoponopono ai i kēia pilikia, ua koho mākou i nā mea metala ikaika loa a ua hoʻolālā i kahi bracket projector e hiki ke hoʻololi i nā puka paʻa o ka hapa nui o nā projectors a loaʻa i kahi pae pitch nui.

Hana ʻia kēia bracket kūikawā i ke kila rectangular a me ke kila kihi. Hiki iā ia ke hoʻokō i kahi kihi pitch nui mai 0 ° a 85 °. Paʻa paʻa a kūpaʻa i ke ōlaʻi a ʻaneʻane ʻaʻole maʻalahi e hoʻopilikia ʻia e nā mana kūlohelohe kūlohelohe a me nā hui ʻole luku ʻole.
