Indima yeemodulators zesigaba seemoto
Umsebenzi we-automobile phase modulator kukusebenzisa i-modulating signal ukutshintsha ngokuthe ngqo iiparameter ze-resonant loop, ukuze i-carrier signal ivelise i-phase shift xa idlula kwi-resonant loop kwaye yenze i-phase-modulated wave. Ukusetyenziswa kwe-phase modulator kwi-automobile kubonakala kakhulu kulawulo oluguquguqukayo lwe-injini intake phase kunye ne-exhaust phase ukuphucula ukusebenza kunye nokusebenza kakuhle kwe-injini .
Umgaqo wokusebenza we-phase modulator usekelwe kwisiphumo se-electro-optical esithe ngqo, esilungisa isigaba se-light wave ngokutshintsha amandla entsimi yombane. Kwicandelo leemoto, ii-phase modulators zisetyenziselwa ukulawula i-intake phase regulator kunye ne-exhaust phase regulator, ngaloo ndlela kuphucula inkqubo yokutsha kunye nokusebenza kakuhle kwe-exhaust yenjini.
Iimeko ezithile zokusetyenziswa ziquka: phantsi kweemeko zesantya esiphantsi okanye umthwalo ophantsi, umlawuli wesigaba sokungenisa unokuphucula ixesha lokuvala kwevalvu yokungenisa ngokufanelekileyo, uphucule isiphumo se-swirl kunye ne-roll kwisilinda, kwaye uphucule uzinzo lokutsha; Ngesantya esiphezulu okanye umthwalo ophezulu, iya kulibazisa ixesha lokuvala kwevalvu yokungenisa, yonyuse ubude be-stroke yokungenisa, kwaye iphucule amandla enjini. Ukongeza, ii-phase modulators zikwasetyenziswa kwiimoto ezingenamqhubi, ii-biosensors ze-on-chip kunye nezinye iindawo ukufezekisa imisebenzi enzima ngakumbi yolawulo lwe-optical kunye nokucubungula imiqondiso .
I-phase modulator yindlela yokuguqula apho i-phase yomthwali we-carrier iphambuka kwi-reference phase yayo ngokulingana nexabiso elikhawulezileyo lesignali eguquliweyo . Umgaqo wokusebenza we-phase modulator usekelwe kolu tshintsho, ngokulungelelanisa i-phase yomthwali ukuze athwale ulwazi.
Iimodulators zesigaba zisetyenziswa kakhulu kunxibelelwano, ukulinganisa i-optical kunye nolawulo lwe-beam. Umzekelo, kunxibelelwano lwe-optical lwesithuba, iimodulators zesigaba zinokufikelela ekuphambukeni kwe-beam ngokulawula isigaba se-wavefront, esinexabiso elibalulekileyo lokusetyenziswa kwezobuchwepheshe eziphambili ezifana nokufunyanwa kwethagethi, ukulandelela kunye nokujolisa.
Iingenelo ze-phase modulator ziquka uvakalelo oluphezulu kunye nokusebenza kakuhle, kodwa ingxaki kukuba ingasetyenziselwa kuphela ukulinganisa okulinganiselweyo kwaye ayinakusetyenziswa ukulinganisa ubungakanani bemeko. Ukongeza, i-phase modulation ineempawu zovakalelo oluphezulu kwi-optical fiber sensing, kodwa ikwanazo nemida yayo.
