Los ntawm kev tswj hwm theem ntawm lub nqaj nyob rau hauv lub nqaj nyob rau hauv lub nqaj array, cov kev cai kho qhov muag tau paub meej ntawm cov npoo nqaj ntses yog qhov dav hlau. Nws muaj qhov zoo ntawm cov ntim me me thiab loj ntawm cov kab ke, cov lus teb ceev ceev thiab cov nqaj zoo zoo.
Tus qauv ua hauj lwm ntawm Optical kaujed array tshuab yog kom ua haujlwm zoo (lossis ncua) lub teeb liab ntawm lub hauv paus kev txiav txim raws li qhov kev cai lij choj kom tau txais kev def ntawm hneev. Raws li cov lus txhais saum toj no, kho qhov muag ntsuas hluav taws xob suav nrog kev cuam tshuam txog kev ua kom muaj teeb meem tseem ceeb
Los ntawm emission pom, lub kauj ruam kho qhov muag yog los tswj cov nqaj kis tau los ntawm cov nqaj sib kis tau yooj yim. Lub hauv paus ntsiab lus ntawm kho qhov muag theem yog muaj nyob hauv Daim Duab. 1. Daim duab. 1 (a) yog ib qho xwm txheej hluavtaws incotherent, uas yog, tsuas muaj "array" tsis muaj "phased array". Daim duab 1 (B) ~ (d) qhia txog peb qhov sib txawv ua haujlwm ntawm kev ua haujlwm kho qhov muag theem ntawm kev kho qhov muag theem (uas yog, coherent hluavtaws array).
Incoherent synthesis system tsuas yog nqa tawm cov fais fab yooj yim ntawm array nqaj tsis tswj cov theem ntawm array nqaj. Nws lub chaw teeb ci tuaj yeem yog ntau cov lasers nrog cov khoom sib txawv, thiab kev ywj pheej ntawm cov khoom sib pauv ntawm cov nqaj hlau, Yog li nws tsis tuaj yeem suav ua ntu ntawm cov phased hauv qhov kev nkag siab tseeb. Txawm li cas los xij, kev siv hluavttheres inclouse tau siv dav dav vim nws cov qauv yooj yim, qhov yuav tsum tau ua ntawm lub teeb ua tau zoo thiab muaj zog tso zis.
Los ntawm cov kev pom ntawm tau txais, kho qhov muag theem array yog thov rau hauv kev daws teeb meem siab ntawm cov hom phiaj ntawm cov hom phiaj (Daim duab 2). Nws yog tsim ntawm lub tsom iav tsom array, theem retarder array, nqaj sib txuas thiab ntsuas cov cuab yeej. Cov txheej txheem ua ke ntawm lub hom phiaj tau txais. Lub hom phiaj duab yog xam raws li cov kiv cua fansstert-zernick theorem. Cov txheej txheem no yog hu ua kev cuam tshuam kev ntsuas cov txheej txheem, uas yog ib qho ntawm cov khoom siv tshuab hluavtaws cov txheej txheem. From the perspective of system structure, the structure of interferometric imaging system and phased array emission system is basically the same, but the optical path transmission direction in the two applications is opposite.
