Ngokulawula isigaba somgca weyunithi kwi-beam array, iteknoloji ye-optical phased array inokuqonda ukwakhiwa kwakhona okanye umgaqo ochanekileyo we-array beam isopic plane.Ineenzuzo zomthamo omncinci kunye nobunzima benkqubo, isantya sokuphendula ngokukhawuleza kunye nomgangatho olungileyo we-beam.
Umgaqo osebenzayo weteknoloji ye-optical phased array kukutshintsha ngokufanelekileyo (okanye ukulibazisa) umqondiso wesiseko esicwangciswe ngokomthetho othile ukuze ufumane ukuphambuka kwe-array beam.Ngokwale ngcaciso ingentla, itekhnoloji ye-optical phased array ibandakanya itekhnoloji yoguqulo lwe-angle enkulu yokukhutshwa kwe-beam kunye noluhlu lwetekhnoloji yokuphazamiseka kokuphazamiseka kwetekhnoloji ye-imaging yesisombululo esiphezulu seethagethi ezikude.
Ukusuka kwindawo yokujonga, i-optical phased array kukulawula isigaba se-array transmitted beam, ukuze kuqondwe ukuphambuka ngokubanzi kwe-array beam okanye imbuyekezo yempazamo yesigaba.Umgaqo osisiseko we-optical phased array iboniswe kwi-FIG.1. IFIG.I-1 (a) luluhlu olungahambelaniyo lokwenziwa, oko kukuthi, kukho kuphela "uluhlu" ngaphandle "kwezigaba ezinezigaba".Umzobo 1 (b) ~ (d) ubonisa iimeko ezintathu ezahlukeneyo zokusebenza zoluhlu olunezigaba zokubona (oko kukuthi, uluhlu oluhambelanayo lokwenziwa).
Inkqubo yokudityaniswa engahambelaniyo iqhuba kuphela amandla angaphezulu alula e-array beam ngaphandle kokulawula isigaba se-array beam.Umthombo wayo wokukhanya unokuba zii-laser ezininzi ezinobude obuhlukeneyo, kwaye ubungakanani bendawo ekude bugqitywe bubungakanani beyunithi yokuhambisa uluhlu, ngokuzimeleyo kwinani lezinto zoluhlu, i-aperture elinganayo yoluhlu kunye nomlinganiso womsebenzi we-array yoluhlu, ngoko ayinakubalwa njengoluhlu olunezigaba ngokwenyani.Nangona kunjalo, inkqubo ye-synthesis engahambelaniyo isetyenziswe ngokubanzi ngenxa yesakhiwo sayo esilula, imfuno ephantsi ekusebenzeni komthombo wokukhanya kunye namandla aphezulu okuvelisa.
Ukususela kumbono wokufumana, i-optical phased array isetyenziswe kwi-imaging ye-high-resolution yethagethi ezikude (FIG. 2).Yenziwe ngoluhlu lweteleskopu, uluhlu lwe-phase retarder, i-beam combinator kunye nesixhobo sokucinga.Ukuhambelana okuntsonkothileyo komthombo ekujoliswe kuwo kufunyenwe.Umfanekiso ojoliswe kuwo ubalwa ngokwethiyori yeFanssert-Zernick.Obu buchule bubizwa ngokuba bubuchule bokucinga ngokuphazamisa, obuyenye yeendlela zokwenziwa zokucinga ngokuvula indawo.Ngokombono wesakhiwo senkqubo, isakhiwo se-interferometric imaging system kunye ne-pased array emission system ngokusisiseko iyafana, kodwa indlela yokuhambisa i-optical path in the two applications ichasene.
