Yintoni iteknoloji ye-optical phased array?

Ngokulawula isigaba somgca weyunithi kwi-beam array, iteknoloji ye-optical phased array inokuqonda ukwakhiwa kwakhona okanye ukulawulwa ngokuchanekileyo kwendiza ye-isopic ye-array. Ineenzuzo zomthamo omncinci kunye nobunzima benkqubo, isantya sokuphendula ngokukhawuleza kunye nomgangatho olungileyo we-beam.

Umgaqo wokusebenza weteknoloji ye-optical phased array kukutshintsha ngokufanelekileyo (okanye ukulibazisa) umqondiso wesiseko esicwangciswe ngokomthetho othile ukufumana ukuphambuka kwe-array beam. Ngokwale nkcazo ingentla, itekhnoloji ye-optical phased array ibandakanya itekhnoloji yokuphambuka kwe-engile enkulu yokukhutshwa kwe-beam kunye noluhlu lwetekhnoloji yokuphazamiseka kwetekhnoloji yokujonga itekhnoloji yesisombululo esiphakamileyo 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, imfuneko 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 okuntsokothileyo komthombo ekujoliswe kuwo kufunyenwe. Umfanekiso ojoliswe kuwo ubalwa ngokwethiyori yeFanssert-Zernick. Obu buchule bubizwa ngokuba bubuchule bokucinga ngokuphazamisa, obunye bobuchule bokwenziwa komfanekiso wokuvula umngxuma. 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.
