Qhov txawv ntawm qhov muag kho qhov muag yog qhov ntsuas hluav taws xob kev tsim kho thiab cov kauj ruam ntawm cov kauj ruam lossis cov kauj ruam txuas ntxiv ntawm cov txheej txheem (lossis cov npoo ntawm cov khoom siv kho tshiab ntawm ib txwm). Qhov txawv txav kho qhov muag yog nyias, lub teeb, me me hauv qhov loj me, muaj ntau cov qauv tsim kev ywj pheej, zoo thermal stability thiab cim dispersion yam ntxwv. Lawv yog qhov tseem ceeb ntawm ntau cov twj kho dua tshiab. Txij li qhov sib txawv tas li ua rau qhov kev txwv ntawm cov kev daws teeb meem zoo los ntawm kev ua kom zoo thiab muaj kev vam meej thiab lub computer hologram tshwm sim a Kev hloov pauv zoo heev hauv lub tswvyim. Nyob rau xyoo 1970, txawm hais tias thev naus laus zis ntawm lub koos pij tawj muaj ntau yam zoo tshaj plaws, nws tseem muaj ntau yam kev ua tiav ntawm cov tswv yim ntawm cov tswv yim ntawm cov khoom siv kho qhov muag Cov. Xyoo 1980, cov pab pawg tshawb fawb coj los ntawm Wbveldkamp los ntawm kev tsim tawm ntawm cov neeg siv tshuab hluav taws xob, thiab npaj siab lub tswvyim ntawm "Binary Optics". Tom qab hais tias, ntau txoj kev tshiab txuas ntxiv tawm, suav nrog kev tsim cov khoom muaj txiaj ntsig zoo thiab muaj ntau yam kho qhov muag. Yog li muaj kev txhawb nqa zoo tshaj plaws ntawm kev txhim kho ntawm differactactence optical.
Qhov txawv kev ua tau zoo ntawm cov khoom siv kho qhov muag
Kev ua qhov sib txawv yog ib qho tseem ceeb rau kev soj ntsuam diffuractive optical cov khoom thiab sib xyaw ua ke kho qhov muag nrog cov khoom siv sib txawv. Tom qab lub teeb hla dhau ntawm cov qauv hloov kho kho qhov muag, ntau qhov kev txiav txim sib txawv yuav tsim tawm. Feem ntau, tsuas yog lub teeb ntawm lub ntsiab diffraction yog them rau. Lub teeb ntawm lwm cov kev txiav txim sib txawv yuav ua rau lub teeb pom kev ntawm cov duab dav hlau ntawm lub ntsiab differraction thiab txo qhov sib txawv ntawm cov duab dav hlau. Yog li ntawd, qhov txawv kev ua haujlwm ntawm cov khoom siv hloov kho tshiab cuam tshuam rau cov duab zoo ntawm cov khoom siv kho qhov muag zoo.
Kev loj hlob ntawm cov khoom siv kho qhov muag
Vim yog cov qauv hloov kho tshiab thiab nws txoj kev tswj hwm hloov tau zoo tag nrho, lub khoos phis tawm kho kho tshiab thiab cov khoom siv tau txhim kho mus rau lub teeb, miniaterized thiab kev sib xyaw. Txog rau thaum xyoo 1990, txoj kev kawm ntawm cov khoom siv hloov kho qhov muag tau dhau los ua ntej ntawm qhov kho qhov muag. Cov khoom siv no tuaj yeem siv tau dav hauv laser wavefrics kho, nqaj profile kho qhov muag, kev sib txuas lus kho qhov muag, Satellite qhov kev sib txuas lus thiab lwm yam.
