Cov theem sib txawv ntawm qhov ntsuas ntsuas iav pyramid fabrication: thaum nyob rau hauv kev sib cuag nrog lub hnub ci ntawm lub hnub ci, lub pyramid ntawm cov kauj ruam kawg (hauv qab txoj cai kaum) absorbs thiab concentrates feem ntau ntawm qhov teeb meem teeb thiab tshwm tsaus nti.

Hnub ci vaj huam sib luag yuav ua lub luag haujlwm tseem ceeb hauv kev tsim hluav taws xob ruaj khov rau yav tom ntej tab sis lawv ua haujlwm zoo tshaj plaws thaum hnub ci tsoo lawv ncaj qha. Qhov no tuaj yeem yog teeb meem thaum lub hnub ci ntsa iab los ntawm huab cua lossis raws li lub hnub dhau los saum toj no txhua hnub.
Ntau lub hnub ci arrays nquag tig mus rau lub hnub kom ntes tau lub zog ntau li ntau tau. Qhov no ua rau lawv kim dua thiab nyuaj los tsim thiab tswj dua li cov uas nyob ruaj ruaj.
Tab sis tsivhnub ci vaj huam sib luagtej zaum yuav tsis tsim nyog nyob rau yav tom ntej, vim tias tus kws tshawb fawb engineering tau tsim cov cuab yeej uas tuaj yeem ntes 90 feem pua ntawm lub teeb uas ntog rau nws - tsis hais nws lub kaum sab xis lossis zaus - thiab mloog zoo rau nws kom peb lub zog ci dua.

"Nws yog ib qho kev ua tiav tag nrho - nws tsis tas yuav muaj zog los taug qab qhov chaw lossis muaj qhov txav mus los," hais tias thawj tus kws sau ntawv Dr Nina Vaidya, uas ua tiav qhov kev tshawb fawb ua tus kws kho mob ntawm Standford University, Asmeskas, thiab tam sim no yog tus pab. xib fwb hauv astronautics thiab spacecraft engineering ntawm University of Southampton, UK.
"Yog tsis muaj kev tsom pom qhov muag uas txav tau txoj haujlwm lossis xav tau rau kev taug qab cov kab ke, kev tsom mus rau lub teeb yuav yooj yim dua."
AGILE – Axially Graded Index Lens
Cov cuab yeej hu ua AGILE, uas sawv cev rau axially graded index lens, thiab nws zoo li lub khob sab saum toj nrog lub ntsiab lus txiav tawm.
Nws ua haujlwm me ntsis li cas aiav magnifyingtuaj yeem tsom lub hnub ci rau hauv qhov me me, ci ntsa iab ntawm hnub ci. Tab sis lub iav magnifying focal point txav raws li lub hnub ua, uas tsis muaj txiaj ntsig thaum koj xav mloog lub hnub ci mus rau thaj chaw tshwj xeeb ntawm lub cell photovoltaic thoob plaws hnub.
Nrog AGILE, lub teeb nkag mus rau qhov dav, square sab saum toj ntawm txhua lub ces kaum thiab yog funneled cia kom mloog zoo rau tib txoj hauj lwm hauv qab - tsim kom muaj qhov ci ntsa iab ntawm lub hauv paus nqaim uas zaum saum lub cell photovoltaic.
"Peb xav tsim ib yam dab tsi uas siv rau hauv lub teeb thiab ua kom pom tseeb ntawm tib txoj haujlwm, txawm tias qhov chaw hloov pauv kev coj ua," piav qhia Vaidya. "Peb tsis xav kom yuav tsum tau txav peb lub tshuab ntes lossis lub hnub ci cell, lossis txav lub kaw lus mus rau qhov chaw.
Tus kws sau ntawv laus Olav Solgaard, tus xibfwb ntawm hluav taws xob engineering ntawm Stanford thiab Vaidya tus kws tshaj lij kws pab tswv yim, hais tias: "Ib qho zoo tshaj plaws AGILE muaj, nyob rau hauv pem hauv ntej ntawm nws, tib lub refractive index raws li huab cua thiab nws maj mam nce siab dua - lub teeb khoov nyob rau hauv ib tug zoo kawg nkaus. du nkhaus.
"Tab sis hauv qhov xwm txheej, koj yuav tsis muaj qhov zoo tshaj plaws AGILE."
Hloov chaw, tus qauv AGILE yog tsim los ntawm qhov hu ua cov khoom siv ntsuas ntsuas, uas muaj cov txheej txheem sib txawv ntawm cov tsom iav thiab cov polymers uas khoov lub teeb mus rau qhov sib txawv. Cov khaubncaws sab nraud povtseg hloov lub teeb nkag mus rau hauv cov kauj ruam kom txog rau thaum nws los nyob rau hauv yuav luag vertically ntawm cov zis.
Siv AGILE los ntawm kev xav mus rau qhov tseeb
Ib qho ntawm cov teeb meem loj tshaj plaws hauv kev tsim cov qauv AGILE yog nrhiav thiab tsim cov khoom lag luam zoo uas tuaj yeem tso rau hauv qhov dav dav ntawm lub teeb, tso cai rau nws hla, thiab khoov nws nce mus rau qhov tso zis - tag nrho thaum sib haum nrog ib leeg. .
Piv txwv li, yog tias ib lub khob nthuav dav hauv cov lus teb rau cov cua sov ntawm qhov sib txawv dua li lwm tus, tag nrho cov cuab yeej tuaj yeem tawg. Cov ntaub ntawv tseem xav tau kom muaj zog txaus los ua kom zoo thiab nyob ruaj khov.
Ob sab ntawm cov qauv no tseem mirrored kom thaws txhua lub teeb mus rau qhov tsis ncaj ncees lawm rov qab mus rau hauv paus.
Cov khoom siv AGILE no tuaj yeem ntsia tau rau hauv ib txheej rau saumhnub ci hlwb, hloov lub encapsulation uas twb muaj lawm uas tiv thaiv hnub ci arrays, thiab txawm yuav tsim ntau qhov chaw txias thiab circuitry khiav ntawm lub nqaim pyramids ntawm ib tug neeg li.
"Yuav kom siv tau cov ntaub ntawv tshiab no, cov txheej txheem tsim tawm tshiab no thiab lub tswv yim tshiab AGILE no los tsim kom muaj lub hnub ci zoo dua tau txais txiaj ntsig zoo," Vaidya xaus lus.
"Kev nplua nuj thiab pheej yig lub zog huv yog ib feem tseem ceeb ntawm kev daws cov teeb meem kev nyab xeeb thiab kev ruaj ntseg, thiab peb yuav tsum tau ua kom muaj kev daws teeb meem engineering kom ua tau qhov tseeb."
