Nekudzora chikamu chedanda reyuniti mudanda remachira, tekinoroji ye optical phased array inogona kugadzira patsva kana kugadzirisa zvakananga danda re isopic plane re array beam. Ine zvakanakira zvehukuru hudiki uye huremu hwesystem, kumhanya nekukurumidza kwemhinduro uye mhando yakanaka yedanda.
Nheyo yekushanda kwetekinoroji ye optical phased array ndeyekushandura zvakanaka (kana kunonotsa) chiratidzo chechinhu chepasi chakarongwa zvichienderana nemutemo wakati kuti pave nekutsauka kwedanda re array. Zvichienderana netsananguro iri pamusoro, tekinoroji ye optical phased array inosanganisira tekinoroji ye large-angle beam deflection ye beam emission arrays uye tekinoroji ye array telescope interference imaging ye high-resolution imaging ye kure-targets.
Kubva pakuona kwekubuda kwemhepo, optical phased array ndeyekudzora phase yearray transmitted beam, kuitira kuti ione kutsauka kwese kwearray beam kana kuti phase error compensation. Nheyo huru ye optical phased array inoratidzwa muMufananidzo 1. Mufananidzo 1 (a) i incoherent synthetic array, kureva kuti, pane "array" chete isina "phased array". Mufananidzo 1 (b) ~ (d) unoratidza mamiriro matatu akasiyana ekushanda kwe optical phased array (ndiko kuti, coherent synthetic array).
Sisitimu yekugadzira isina kurongeka inongoshandisa simba rakareruka rekuisa mwenje wearray pasina kudzora chikamu chemwenje wearray. Chitubu chayo chechiedza chinogona kuva ma laser akawanda ane ma wavelength akasiyana, uye saizi yenzvimbo iri kure inotsamirwa nehukuru hweyuniti yekutumira array, zvisingabatanidzwi nehuwandu hwezvinhu zvearray, aperture yakaenzana yearray uye duty ratio yebeam array, saka haigone kuverengerwa sephased array mupfungwa chaiyo. Zvisinei, sisitimu yekugadzira isina kurongeka yakashandiswa zvakanyanya nekuda kwechimiro chayo chiri nyore, kudiwa kushoma pakushanda kwechiedza uye simba rakawanda rekuburitsa.
Kubva pakuona kwekugamuchira, optical phased array inoshandiswa mumifananidzo yepamusoro-soro yezvibodzwa zviri kure (Mufananidzo 2). Inoumbwa netelescope array, phase retarder array, beam combinator uye mudziyo wekufungidzira. Kubatana kwakaoma kwenzvimbo yakanangana nayo kunowanikwa. Mufananidzo wechinangwa unoverengerwa zvichienderana neFansert-Zernick theorem. Iyi nzira inonzi interference imaging technique, inova imwe yenzira dzekugadzira aperture. Kubva pakuona kwechimiro chesystem, chimiro cheinterferometric imaging system uye phased array emission system chakafanana, asi nzira yekutumira nzira ye optical mumashandisirwo maviri aya yakasiyana.
