Ngokulawula isigaba seyunithi yensimbi kuhlelo lwe-beam, ubuchwepheshe be-optical phased array bungakwazi ukubona ukwakhiwa kabusha noma ukulawulwa okunembile kwendiza ye-isopic ye-beam.Inezinzuzo zevolumu encane nesisindo sohlelo, isivinini sokuphendula esisheshayo kanye nekhwalithi enhle ye-beam.
Umgomo wokusebenza wobuchwepheshe be-optical phased array uwukushintsha kahle (noma ukubambezeleka) isiginali ye-elementi yesisekelo ehlelwe ngokuvumelana nomthetho othile ukuze kutholwe ukuchezuka komugqa wohlelo.Ngokwale ncazelo engenhla, ubuchwepheshe be-optical phased array buhlanganisa ubuchwepheshe bokuchezuka kwe-engeli enkulu ye-beam emission arrays kanye nobuchwepheshe be-imaging be-telescope obuphazanyiswayo bokuthwebula izithombe ezinokulungiswa okuphezulu kokuhlosiwe okukude.
Kusukela endaweni yokubuka, amalungu afanayo ahlukaniswe ngezigaba ukulawula isigaba somugqa odluliswayo, ukuze kubonakale ukuchezuka kukonke kwebhimu yamalungu afanayo noma isinxephezelo sephutha lesigaba.Umgomo oyisisekelo we-optical phased array uboniswa ku-FIG.1. UMKHW.1 (a) iwuhlelo olungahlangene lokwenziwa, okungukuthi, kukhona kuphela “amalungu afanayo” angenayo “amalungu afanayo ahlukaniswe ngezigaba”.Umfanekiso 1 (b) ~ (d) ubonisa izimo zokusebenza ezintathu ezihlukene zamalungu afanayo ahlukaniswe ngezigaba (okungukuthi, amalungu afanayo okwenziwa).
Isistimu ye-synthesis engaqondakali yenza kuphela amandla aphezulu alula we-array beam ngaphandle kokulawula isigaba somugqa wohlelo.Umthombo wawo wokukhanya ungaba ama-laser amaningi anamaza ahlukene ahlukene, futhi usayizi wendawo yenkundla ekude inqunywa usayizi weyunithi yohlelo oluthumelayo, ngaphandle kwenani lezakhi zohlelo, indawo yokuvula efanayo yohlelo kanye nenani lomsebenzi wesilinganiso somugqa, ngakho angeke ibalwe njengohlu olunezigaba ngomqondo weqiniso.Kodwa-ke, isistimu ye-synthesis engaqondakali isetshenziswe kabanzi ngenxa yesakhiwo sayo esilula, isidingo esiphansi ekusebenzeni komthombo wokukhanya namandla aphezulu okukhipha.
Kusuka kumbono wokwamukela, i-optical phased array isetshenziswa ekufanekisweni kokulungiswa okuphezulu kokuhlosiwe okukude (FIG. 2).Yakhiwe nge-telescope array, isigaba se-retarder array, i-beam combinator kanye nedivayisi yokucabanga.Ukuhlangana okuyinkimbinkimbi komthombo okuhlosiwe kuyatholakala.Isithombe okuhloswe ngaso sibalwa ngokuya ngethiyori ye-Fanssert-Zernick.Le nqubo ibizwa ngokuthi inqubo ye-interference imaging, okungenye yezindlela zokwenziwa ze-synthetic ye-aperture imaging.Ngokombono wesakhiwo sesistimu, ukwakheka kwesistimu ye-imaging ye-interferometric kanye nesistimu yokukhishwa kwe-array ehlukanisiwe ngokuyisisekelo kuyafana, kodwa isiqondiso sokudlulisa indlela yokubona kulezi zicelo ezimbili siphambene.
