I-Spatial light modulator isho ukuthi ngaphansi kokulawula okusebenzayo, ingakwazi ukulungisa amanye amapharamitha enkambu yokukhanya ngokusebenzisa ama-molecule ekristalu ewuketshezi, njengokushintsha ubukhulu benkambu yokukhanya, ukulungisa isigaba ngenkomba ye-refractive, ukulungisa isimo se-polarization ngokuzungezisa indiza ye-polarization. , noma ukuqaphela ukuguqulwa kokukhanya okungahambisani - okuhambisanayo, ukuze kubhalwe ulwazi oluthile kugagasi lokukhanya, ukufeza injongo yokuguqulwa kwegagasi lokukhanya.Ingakwazi ukulayisha kalula ulwazi endaweni eyodwa noma ezimbili ze-optical, futhi isebenzise izinzuzo zebhande elibanzi lokukhanya, ukucubungula okuhambisanayo kweziteshi eziningi nokunye ukucubungula ulwazi olulayishiwe ngokushesha.Iyingxenye eyinhloko yokucubungula ulwazi lwesikhathi sangempela, ukuxhumeka kwe-optical, i-optical computing nezinye izinhlelo.
Umgomo wokusebenza we-spatial light module
Ngokuvamile, imojuli yokukhanya yendawo iqukethe inani lamayunithi azimele, ahlelwa ngohlangothi olulodwa noma olukabili-ntathu esikhaleni.Iyunithi ngayinye ingathola ukulawulwa kwesignali yokubona noma isignali kagesi ngokuzimela, futhi iguqule izakhiwo zayo zokubona ngokuya ngesignali, ukuze ilinganise igagasi lokukhanya elikhanyiswe kuyo.Imishini enjalo ingashintsha i-amplitude noma ukushuba, isigaba, isimo se-polarization kanye nobude begagasi be-optical ukusatshalaliswa emkhathini, noma iguqule ukukhanya okungahlangani kube ukukhanya okuhambisanayo ngaphansi kokulawula okushayelwa ngogesi noma amanye amasiginali ashintsha ngokuhamba kwesikhathi.Ngenxa yalesi sakhiwo, singasetshenziswa njengeyunithi yokwakha noma idivayisi eyisihluthulelo ekucutshungulweni kolwazi lwesikhathi sangempela, ukubala kwe-optical kanye nezinhlelo zenethiwekhi ye-optical neural.
I-modulator yokukhanya yendawo ingahlukaniswa ngohlobo lokubonisa kanye nohlobo lokudlulisela ngokuya ngemodi yokufunda ehlukile yokukhanya.Ngokwesiginali yokulawula okokufaka, ingahlukaniswa ibe ikheli le-optical (OA-SLM) kanye nekheli likagesi (EA-SLM).
Ukusetshenziswa kwe-modulator yokukhanya yendawo
I-valve yokukhanya yekristalu ewuketshezi esebenzisa ukukhanya - ukuguqulwa okuqondile okukhanyayo, ukusebenza kahle okuphezulu, ukusetshenziswa kwamandla okuphansi, isivinini esisheshayo, ikhwalithi enhle.Ingasetshenziswa kabanzi ku-optical computing, ukuqashelwa kwephethini, ukucutshungulwa kolwazi, isibonisi kanye nezinye izinkambu, futhi inamathemba okusebenza abanzi.
I-Spatial light module iyithuluzi elibalulekile emikhakheni yesimanje yokubona efana nokucutshungulwa kolwazi lwesikhathi sangempela, i-adaptive optics nokubala kwe-optical.Ngokwezinga elikhulu, ukusebenza kwezimojuli zokukhanya zendawo kunquma inani elingokoqobo namathemba okuthuthukiswa kwale mikhakha.
Izinhlelo zokusebenza eziyinhloko, ukuthwebula isithombe & ukuqagela, ukuhlukaniswa kwemishayo, ukubunjwa kwe-laser beam, ukuguquguquka okuhambisanayo kwe-wavefront, ukushintshwa kwesigaba, ama-tweezers optical, i-holographic projection, i-laser pulse shape, njll.
