Diffraction optical element yog ib yam ntawm cov khoom siv kho qhov muag nrog kev ua haujlwm siab diffraction, uas yog ua raws li txoj kev xav ntawm diffraction ntawm lub teeb nthwv dej thiab siv lub computer-aided tsim thiab semiconductor nti tsim cov txheej txheem los etch cov kauj ruam lossis txuas txuas ntxiv cov qauv ntawm lub substrate (los yog saum npoo. ntawm tsoos optical ntaus ntawv). Diffraction optical ntsiab yog nyias, lub teeb, me me nyob rau hauv loj, nrog siab diffraction efficiency, ntau yam qauv ntawm kev ywj pheej, zoo thermal stability thiab nws dispersion yam ntxwv. 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 qhov kev daws teeb meem siab ntawm qhov kho qhov muag, ib txwm siv optics ib txwm sim zam qhov tsis zoo tshwm sim los ntawm cov nyhuv diffraction mus txog rau xyoo 1960, nrog rau kev tsim khoom thiab kev ua tiav ntawm analog holography thiab computer hologram nrog rau cov kab kos theem ua rau muaj kev vam meej. kev hloov loj hauv lub tswvyim. Nyob rau xyoo 1970, txawm hais tias cov thev naus laus zis ntawm lub khoos phis tawj hologram thiab daim duab theem tau dhau los ua qhov zoo tshaj plaws, nws tseem nyuaj los ua cov qauv hyperfine nrog kev ua haujlwm siab diffraction nyob rau hauv pom thiab nyob ze infrared wavelengths, yog li txwv qhov kev siv ntau yam ntawm diffractive optical ntsiab. . Nyob rau xyoo 1980, Ib pab pawg tshawb fawb coj los ntawm WBVeldkamp los ntawm MIT Lincoln Laboratory hauv Tebchaws Meskas thawj zaug qhia txog lithography thev naus laus zis ntawm VLSI kev tsim khoom rau hauv kev tsim cov khoom siv kho qhov muag diffractive, thiab tau npaj lub tswv yim ntawm "binary optics". Tom qab ntawd, ntau txoj kev ua haujlwm tshiab txuas ntxiv mus, suav nrog kev tsim cov khoom zoo thiab cov khoom siv ntau yam diffractive optical. Yog li txhawb kev loj hlob ntawm diffractive optical ntsiab.
Diffraction efficiency ntawm lub diffractive optical keeb
Diffraction efficiency yog ib qho tseem ceeb indexes los soj ntsuam diffractive optical ntsiab thiab sib xyaw diffractive optical systems nrog diffractive optical ntsiab. Tom qab lub teeb dhau los ntawm diffractive optical keeb, ntau qhov kev txiav txim diffraction yuav raug tsim. Feem ntau, tsuas yog lub teeb ntawm lub ntsiab diffraction txiav txim yog them rau. Lub teeb ntawm lwm qhov kev txiav txim diffraction yuav tsim lub teeb stray ntawm daim duab dav hlau ntawm qhov kev txiav txim loj diffraction thiab txo qhov sib piv ntawm cov duab dav hlau. Yog li ntawd, qhov ua tau zoo ntawm diffraction ntawm diffractive optical element ncaj qha cuam tshuam rau cov duab zoo ntawm diffractive optical element.
Kev loj hlob ntawm diffractive optical ntsiab
Vim lub diffractive optical caij thiab nws hloov tau yooj yim tswj yoj pem hauv ntej, lub kho qhov muag system thiab ntaus ntawv yog tsim rau lub teeb, miniaturized thiab integrated. Txog thaum xyoo 1990, txoj kev tshawb fawb ntawm cov khoom siv kho qhov muag tau dhau los ua qhov ua ntej ntawm qhov chaw kho qhov muag. Cov khoom no tuaj yeem siv dav hauv laser wavefront kho, nqaj profile tsim, beam array generator, optical interconnection, optical parallel xam, satellite optical kev sib txuas lus thiab lwm yam.
