Iyini i-modulator yokukhanya kwendawo?

I-Spatial light modulator isho ukuthi ngaphansi kokulawula okusebenzayo, ingashintsha amanye amapharamitha ensimu yokukhanya ngokusebenzisa ama-molecule ekristalu eliketshezi, njengokushintsha ubukhulu bensimu yokukhanya, ukuguqula isigaba ngenkomba yokukhanya, ukuguqula isimo se-polarization ngokujikeleza kwendiza ye-polarization, noma ukubona ukuguqulwa kokukhanya okungaqondakali, ukuze kubhalwe ulwazi oluthile kugagasi lokukhanya, ukuze kufezwe injongo yokuguqulwa kwamagagasi okukhanya. Ingalayisha kalula ulwazi ensimini eyodwa noma ezimbili ze-optical, futhi isebenzise izinzuzo ze-wide band of light, multi-channel parallel processing nokunye ukucubungula ulwazi olulayishiwe ngokushesha. Iyingxenye eyinhloko yokucubungula ulwazi lwe-optical ngesikhathi sangempela, ukuxhumana kwe-optical, i-optical computing nezinye izinhlelo.

Isimiso sokusebenza se-modulator yokukhanya kwendawo

Ngokuvamile, i-spatial light modulator iqukethe inani lamayunithi azimele, ahlelwe ngendlela eyodwa noma ezimbili-dimensional emkhathini. Iyunithi ngayinye ingathola ukulawulwa kwesignali ye-optical noma isignali kagesi ngokuzimela, futhi ishintshe izakhiwo zayo ze-optical ngokwesignali, ukuze iguqule igagasi lokukhanya elikhanyisiwe kuyo. Amadivayisi anjalo angashintsha ubukhulu noma ubukhali, isigaba, isimo se-polarization kanye nobude be-wavelength yokusatshalaliswa kwe-optical emkhathini, noma aguqule ukukhanya okungaqondakali kube ukukhanya okuhlangene ngaphansi kokulawulwa kwezibonakaliso eziqhutshwa ngogesi noma ezinye ezishintsha ngokuhamba kwesikhathi. Ngenxa yalesi sici, singasetshenziswa njengeyunithi yokwakha noma idivayisi eyisihluthulelo ekucubungulweni kolwazi lwe-optical ngesikhathi sangempela, ukubalwa kwe-optical kanye nezinhlelo zenethiwekhi ye-optical neural.

I-modulator yokukhanya kwendawo ingahlukaniswa ngohlobo lokukhanya kanye nohlobo lokudlulisa ngokwendlela yokufunda ehlukile yokukhanya. Ngokwesignali yokulawula yokufaka, ingahlukaniswa ngokwekheli le-optical (OA-SLM) kanye nekheli likagesi (EA-SLM).

Ukusetshenziswa kwe-modulator yokukhanya kwendawo

I-valve yokukhanya kwekristalu yoketshezi esebenzisa ukukhanya - ukuguqulwa okuqondile kokukhanya, ukusebenza kahle okuphezulu, ukusetshenziswa kwamandla aphansi, isivinini esisheshayo, ikhwalithi enhle. Ingasetshenziswa kabanzi ekubalweni kwe-optical, ukuqashelwa kwamaphethini, ukucubungula ulwazi, ukubonisa kanye neminye imikhakha, futhi inamathuba amaningi okusebenzisa.

I-Spatial light modulator iyithuluzi elibalulekile emikhakheni yesimanje ye-optical efana nokucubungula ulwazi lwe-optical ngesikhathi sangempela, i-adaptive optics kanye ne-optical computation. Ngezinga elikhulu, ukusebenza kwe-spatial light modulator kunquma inani elisebenzayo kanye namathuba okuthuthukiswa kwalezi zinsimu.

Izinhlelo zokusebenza eziyinhloko, ukuthwebula izithombe kanye nokuphrojektha, ukuhlukaniswa kwemisebe, ukubumba imisebe ye-laser, ukuguquguquka kwe-wavefront okuqondile, ukuguquguquka kwesigaba, ama-tweezers abonakalayo, ukubumba kwe-holographic, ukubumba kwe-laser pulse, njll.
