Cov khoom siv kho qhov muag diffraction yog ib hom khoom siv kho qhov muag uas muaj kev ua haujlwm zoo diffraction, uas yog raws li kev tshawb fawb diffraction ntawm lub teeb nthwv dej thiab siv kev tsim kho computer-aided thiab cov txheej txheem tsim khoom semiconductor chip los kos cov kauj ruam lossis cov qauv txuas ntxiv mus rau ntawm lub substrate (lossis qhov chaw ntawm cov khoom siv kho qhov muag ib txwm muaj). Cov khoom siv kho qhov muag diffraction yog nyias, sib dua, me me, nrog kev ua haujlwm zoo diffraction, ntau qib tsim ntawm kev ywj pheej, kev ruaj khov thermal zoo thiab cov yam ntxwv dispersion tshwj xeeb. Lawv yog cov khoom tseem ceeb ntawm ntau yam khoom siv kho qhov muag. Txij li thaum diffraction ib txwm ua rau muaj kev txwv ntawm kev daws teeb meem siab ntawm lub kaw lus kho qhov muag, cov khoom siv kho qhov muag ib txwm sim zam cov teebmeem tsis zoo los ntawm kev cuam tshuam diffraction txog xyoo 1960, nrog rau kev tsim khoom thiab kev tsim khoom zoo ntawm analog holography thiab computer hologram nrog rau daim duab theem ua rau muaj kev hloov pauv loj hauv lub tswv yim. Xyoo 1970, txawm hais tias thev naus laus zis ntawm computer hologram thiab daim duab theem tau dhau los ua qhov zoo tshaj plaws, nws tseem nyuaj rau ua cov khoom siv qauv hyperfine nrog kev ua haujlwm zoo diffraction hauv qhov pom thiab ze infrared wavelengths, yog li txwv qhov kev siv tau ntawm cov khoom siv kho qhov muag diffractive. Xyoo 1980, ib pawg kws tshawb fawb uas coj los ntawm Wbveldkamp los ntawm MIT Lincoln Laboratory hauv Tebchaws Meskas tau qhia thawj zaug txog kev siv tshuab lithography ntawm VLSI rau hauv kev tsim cov khoom siv kho qhov muag diffractive, thiab tau hais txog lub tswv yim ntawm "binary optics". Tom qab ntawd, ntau txoj kev ua haujlwm tshiab tseem tshwm sim, suav nrog kev tsim cov khoom siv kho qhov muag diffractive zoo thiab muaj ntau yam. Yog li ntawd tau txhawb nqa kev txhim kho cov khoom siv kho qhov muag diffractive.
Kev ua haujlwm ntawm diffraction ntawm ib qho khoom siv kho qhov muag diffractive
Kev ua haujlwm zoo ntawm diffraction yog ib qho ntawm cov ntsuas tseem ceeb los ntsuas cov ntsiab lus diffractive optical thiab cov kab ke diffractive optical sib xyaw nrog cov ntsiab lus diffractive optical. Tom qab lub teeb hla dhau cov ntsiab lus diffractive optical, ntau qhov kev txiav txim diffraction yuav tsim. Feem ntau, tsuas yog lub teeb ntawm qhov kev txiav txim diffraction tseem ceeb xwb. Lub teeb ntawm lwm qhov kev txiav txim diffraction yuav tsim lub teeb tsis pom kev ntawm lub dav hlau duab ntawm qhov kev txiav txim diffraction tseem ceeb thiab txo qhov sib piv ntawm lub dav hlau duab. Yog li ntawd, qhov kev ua haujlwm zoo ntawm diffraction ntawm cov ntsiab lus diffractive optical cuam tshuam ncaj qha rau qhov zoo ntawm cov duab ntawm cov ntsiab lus diffractive optical.
Kev tsim cov khoom siv kho qhov muag diffractive
Vim yog lub teeb pom kev zoo diffractive thiab nws lub zog tswj nthwv dej yooj ywm, lub kaw lus kho qhov muag thiab lub cuab yeej tau tsim kom muaj lub teeb, me me thiab sib xyaw ua ke. Txog rau xyoo 1990, kev kawm txog cov teeb pom kev zoo diffractive tau dhau los ua qhov tseem ceeb ntawm lub teeb pom kev zoo. Cov khoom no tuaj yeem siv dav hauv kev kho laser nthwv dej, kev tsim cov qauv beam, lub tshuab hluav taws xob beam, kev sib txuas lus optical, kev suav sib luag optical, kev sib txuas lus satellite optical thiab lwm yam.
