Lisebelisoa tsa sejoale-joale tsa optics tse etelletsoeng pele ke li-modulator tsa optical
Molao-motheo oaphetoho ea opticalha e rarahane. Haholo-holo e fihlella phetoho ea amplitude, phase, polarization, refractive index, sekhahla sa ho monya le litšobotsi tse ling tsa khanya ka har'a lintho tse susumetsang kantle, ho laola lets'oao la optical ka nepo, joalo ka ho nolofalletsa li-photon ho jara le ho fetisa tlhahisoleseling. Likarolo tsa motheo tsa sesebelisoa se tloaelehilengmodulator ea electro-optice kenyelletsa likarolo tse tharo: likristale tsa electro-optic, li-electrode, le likarolo tsa optical. Nakong ea ts'ebetso ea ho feto-fetoha ha leseli, thepa e ka har'a modulator ea optical e fetola index ea eona ea refractive, sekhahla sa ho monya le thepa e meng tlas'a tšusumetso ea lintho tse susumetsang kantle (joalo ka masimo a motlakase, masimo a molumo, liphetoho tsa mocheso kapa matla a mechini), ka hona e ama boitšoaro ba li-photon ha li ntse li feta ka har'a thepa, joalo ka ho laola litšobotsi tsa ho ata ha leseli (amplitude, phase, polarization, jj.). Kristale ea electro-optical ke motheo oamodulator ea optical, e ikarabellang bakeng sa ho arabela diphetohong tse etsahalang tshimong ya motlakase le ho fetola index ya yona ya refractive. Di-electrode di sebediswa ho sebedisa masimo a motlakase, ha dikarolo tsa optical tse kang di-polarizer le di-waveplate di sebediswa ho tataisa le ho sekaseka di-photon tse fetang ka hara kristale.
Likopo tsa Frontier ho Optics
1. Pontšo ea holographic le theknoloji ea ponts'o
Ponelopeleng ea holographic, tšebeliso ea li-modulator tsa optical tsa sebaka ho fetola maqhubu a khanya a etsahalang hantle ho ka nolofalletsa maqhubu a khanya ho kena-kenana le ho faposa ka tsela e itseng, ho theha kabo e rarahaneng ea tšimo ea leseli. Mohlala, SLM e thehiloeng ho kristale ea metsi kapa DMD e ka fetola karabelo ea optical ea pixel ka 'ngoe ka mokhoa o feto-fetohang, ea fetola litaba tsa setšoantšo kapa pono ka nako ea sebele, e lumellang bashebelli ho bona phello ea mahlakore a mararo ea setšoantšo ho tsoa likhutlong tse fapaneng.
2. Tšimo ea polokelo ea data ea Optical
Theknoloji ea polokelo ea data ea mahlo e sebelisa litšobotsi tsa maqhubu a phahameng le matla a phahameng a leseli ho ngola le ho khetholla tlhahisoleseling ka ho fetola khanya ka nepo. Theknoloji ena e itšetlehile ka taolo e nepahetseng ea maqhubu a khanya, ho kenyeletsoa le ho lokisa boemo ba amplitude, phase le polarization, ho boloka data mecheng ea litaba tse kang li-disc tsa mahlo kapa thepa ea polokelo ea holographic. Li-modulator tsa mahlo, haholo-holo li-modulator tsa mahlo tsa sebaka, li bapala karolo ea bohlokoa ho lumelleng taolo e nepahetseng haholo ea mahlo holim'a lits'ebetso tsa polokelo le tsa ho bala.
Sethaleng sa mahlo, difotoni di tshwana le batantsi ba kgahlehang, ba tantsha ka bokhabane ho latela "melodi" ya dintho tse kang dikristale, dikristale tse metsi le difaeba tsa mahlo. Ba ka fetola tsela ka bokhabane, lebelo, esita le ho apara "diaparo tse mebala" tse fapaneng, ba fetola metsamao le merethetho ya bona, mme ba hlahisa tshebetso e makatsang ka mora e nngwe. Taolo ena e nepahetseng ya difotoni ke senotlolo sa mohlolo sa theknoloji ya mahlakore a nakong e tlang ya mahlo, e leng se etsang hore lefatshe la mahlo le tlale menyetla e sa feleng.
