Mfundo ndi chitukuko cha diffractive kuwala zinthu

Diffraction optical element ndi mtundu wa chinthu chowoneka bwino chomwe chili ndi mphamvu zambiri, zomwe zimachokera ku chiphunzitso cha diffraction of light wave ndipo imagwiritsa ntchito makina opangidwa ndi makompyuta ndi makina opanga semiconductor chip kuti akhazikitse masitepe kapena mawonekedwe opitilira mpumulo pa gawo lapansi (kapena pamwamba. wa chipangizo chamakono cha kuwala).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 imayambitsa kuchepetsedwa kwa mawonekedwe apamwamba a optical system, ma optics achikhalidwe nthawi zonse amayesa kupeŵa zotsatira zoyipa zomwe zimayambitsidwa ndi diffraction mpaka zaka za m'ma 1960, ndikupanga bwino kupanga analogi holography ndi hologram yamakompyuta komanso mawonekedwe a gawo adayambitsa kusintha kwakukulu kwa malingaliro.M'zaka za m'ma 1970, ngakhale teknoloji ya hologram ya makompyuta ndi chithunzithunzi cha gawo chinali kukhala changwiro, kunali kovuta kupanga zinthu zopangira ma hyperfine zokhala ndi mphamvu zambiri zowoneka bwino komanso pafupi ndi mafunde amtundu wa infrared, motero kuchepetsa kugwiritsa ntchito mitundu yosiyanasiyana ya 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 diffractive optical element 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.
