Mfundo ndi chitukuko cha diffractive kuwala zinthu

Diffraction optical element ndi mtundu wa zinthu zowoneka bwino zomwe zimakhala ndi mphamvu zambiri, zomwe zimatengera chiphunzitso cha diffraction of light wave ndikugwiritsa ntchito makina opangidwa ndi makompyuta ndi makina opanga ma semiconductor chip kuti akhazikitse masitepe kapena mawonekedwe opitilira mpumulo pagawo lapansi (kapena pamwamba pa chipangizo chachikhalidwe chowunikira). Zinthu zowoneka bwino ndizoonda, zopepuka, zazing'ono, zokhala ndi magwiridwe antchito apamwamba, magawo angapo aufulu, kukhazikika kwamafuta abwino komanso mawonekedwe apadera amwazikana. Ndizigawo zofunika za zida zambiri zowonera. Popeza kuti diffraction nthawi zonse imabweretsa kuchepetsa kusamvana kwakukulu kwa mawonekedwe a kuwala, mawonekedwe achikhalidwe nthawi zonse amayesa kupeŵa zotsatira zoyipa zomwe zimayambitsidwa ndi diffraction mpaka zaka za m'ma 1960, ndi kupanga ndi kupanga bwino kwa analogi holography ndi hologram yamakompyuta komanso chithunzi cha gawo chinayambitsa kusintha kwakukulu kwa lingaliro. M'zaka za m'ma 1970, ngakhale teknoloji ya hologram ya makompyuta ndi chithunzi cha gawo chinali kukhala changwiro, zinali zovuta kupanga zinthu za hyperfine zomwe zimakhala ndi mphamvu zambiri zowoneka bwino komanso pafupi ndi mafunde a infrared, motero kuchepetsa kugwiritsidwa ntchito kwa zinthu zowoneka bwino. M'zaka za m'ma 1980, gulu lofufuza lotsogozedwa ndi WBVeldkamp lochokera ku MIT Lincoln Laboratory ku United States lidayambitsa ukadaulo wa lithography wa VLSI popanga zida zowoneka bwino, ndipo adapereka lingaliro la "binary Optics". Pambuyo pake, njira zatsopano zogwirira ntchito zikupitirizabe kuonekera, kuphatikizapo kupanga zida zapamwamba komanso zogwiritsira ntchito multifunctional diffractive Optical. Choncho kwambiri kulimbikitsa chitukuko cha diffractive kuwala zinthu.

Kuchita bwino kwa diffraction optical element

Kuchita bwino kwa diffraction ndi imodzi mwazofunikira zowunikira zinthu zowoneka bwino komanso makina osakanikirana ophatikizika okhala ndi zinthu zowoneka bwino. Kuwala kukadutsa mu diffractive optical element, madongosolo angapo a diffraction adzapangidwa. Kawirikawiri, kuwala kokha kwa dongosolo lalikulu la diffraction kumaperekedwa. Kuwala kwa machitidwe ena osiyanitsa kudzapanga kuwala kosokera pa ndege ya chithunzi cha dongosolo lalikulu la diffraction ndikuchepetsa kusiyana kwa ndege ya fano. Chifukwa chake, magwiridwe antchito a diffraction optical element amakhudza mwachindunji mtundu wa chithunzi cha diffractive Optical element.

Kukula kwa diffractive kuwala zinthu

Chifukwa cha diffractive optical element ndi mawonekedwe ake osinthika owongolera mafunde, mawonekedwe owoneka bwino ndi chipangizocho akupanga kuwala, kocheperako komanso kuphatikiza. Mpaka zaka za m'ma 1990, kuphunzira kwa zinthu zowoneka bwino kwakhala patsogolo pa gawo la kuwala. Zigawozi zitha kugwiritsidwa ntchito kwambiri pakuwongolera mafunde a laser, kupanga mbiri yamtengo, jenereta yamtengo wapatali, kulumikizana kwa kuwala, kuwerengera kofananira, kulumikizana kwa satellite ndi zina zotero.
