Los ntawm kev tswj hwm theem ntawm lub teeb tsa hauv lub teeb array, cov thev naus laus zis optical phased array tuaj yeem paub txog kev tsim kho dua tshiab lossis kev tswj hwm meej ntawm lub dav hlau isopic ntawm lub teeb array. Nws muaj qhov zoo ntawm qhov me me thiab qhov hnyav ntawm lub kaw lus, kev teb sai thiab qhov zoo ntawm lub teeb.
Lub hauv paus ntsiab lus ua haujlwm ntawm cov thev naus laus zis phased array yog kom hloov pauv (lossis ncua) lub teeb liab ntawm lub hauv paus uas tau teeb tsa raws li ib txoj cai tshwj xeeb kom tau txais qhov deflection ntawm lub teeb array. Raws li cov lus txhais saum toj no, cov thev naus laus zis phased array suav nrog cov thev naus laus zis loj-lub kaum sab xis rau cov teeb pom kev zoo thiab cov thev naus laus zis cuam tshuam kev thaij duab array rau kev thaij duab siab ntawm cov hom phiaj deb.
Los ntawm qhov pom ntawm kev tso tawm, cov khoom siv kho qhov muag theem yog los tswj cov theem ntawm cov teeb liab xa mus, kom paub txog qhov kev hloov pauv tag nrho ntawm cov teeb liab array lossis qhov kev them nyiaj yuam kev theem. Lub hauv paus ntsiab lus ntawm cov khoom siv kho qhov muag theem tau qhia hauv daim duab 1. Daim duab 1 (a) yog cov khoom siv hluav taws xob tsis sib xws, uas yog, tsuas muaj "array" tsis muaj "phased array". Daim duab 1 (b) ~ (d) qhia peb lub xeev ua haujlwm sib txawv ntawm cov khoom siv kho qhov muag theem (uas yog, cov khoom siv hluav taws xob sib xws).
Lub kaw lus tsis sib xws tsuas yog ua qhov yooj yim zog superposition ntawm array beam yam tsis tswj hwm theem ntawm array beam. Nws lub teeb qhov chaw tuaj yeem yog ntau lub lasers nrog ntau qhov wavelengths, thiab qhov loj me ntawm qhov chaw deb yog txiav txim siab los ntawm qhov loj me ntawm lub chaw xa array, ywj pheej ntawm tus lej ntawm cov ntsiab lus array, qhov sib npaug ntawm array thiab qhov piv ntawm lub luag haujlwm ntawm beam array, yog li nws tsis tuaj yeem suav tias yog phased array hauv qhov tseeb. Txawm li cas los xij, lub kaw lus tsis sib xws tau siv dav vim nws cov qauv yooj yim, qhov xav tau qis rau kev ua haujlwm ntawm lub teeb thiab lub zog tso zis siab.
Los ntawm qhov pom ntawm kev txais, optical phased array yog siv rau hauv kev thaij duab siab ntawm cov hom phiaj nyob deb (DAIM DUAB 2). Nws yog tsim los ntawm telescope array, phase retarder array, beam combinator thiab imaging device. Qhov sib xws ntawm lub hom phiaj tau txais. Daim duab hom phiaj raug suav raws li Fanssert-Zernick theorem. Cov txheej txheem no hu ua interference imaging technique, uas yog ib qho ntawm cov txheej txheem synthetic aperture imaging. Los ntawm qhov pom ntawm cov qauv system, cov qauv ntawm interferometric imaging system thiab phased array emission system yog qhov zoo ib yam, tab sis qhov kev taw qhia ntawm txoj kev xa mus rau qhov muag pom hauv ob daim ntawv thov yog qhov sib txawv.
