Yintoni i-spatial light modulator?

I-Spatial light modulator ithetha ukuba phantsi kolawulo olusebenzayo, inokuguqula ezinye iiparameter zentsimi yokukhanya ngokusebenzisa iimolekyuli zekristale yolwelo, ezinje ngokuguqula ubukhulu bentsimi yokukhanya, ukuguqula isigaba ngesalathisi sokurhawuzelela, ukuguqula imeko ye-polarization ngokujikeleza kwendiza ye-polarization, okanye ukuqonda ukuguqulwa kokukhanya okungabonakaliyo, ukuze kubhalwe ulwazi oluthile kwi-light wave, ukufezekisa injongo ye-light wave modulation. Ingalayisha ulwazi ngokulula kwi-optical field enye okanye ezimbini, kwaye isebenzise iingenelo ze-wide band of light, multi-channel parallel processing kunye nokunye ukuze icubungule ulwazi olulayishiweyo ngokukhawuleza. Liyinxalenye ephambili ye-real-time optical information processing, optical interconnection, optical computing kunye nezinye iinkqubo.

Umgaqo wokusebenza we-modulator yokukhanya kwendawo

Ngokubanzi, i-spatial light modulator ineeyunithi ezininzi ezizimeleyo, ezicwangciswe ngendlela enomlinganiselo omnye okanye emibini kwindawo. Iyunithi nganye inokufumana ulawulo lwesignali ye-optical okanye isignali yombane ngokuzimeleyo, kwaye itshintshe iipropati zayo ze-optical ngokwesignali, ukuze iguqule i-light wave ekhanyisiweyo kuyo. Ezi zixhobo zinokutshintsha ubukhulu okanye ubunzulu, isigaba, imeko ye-polarization kunye nobude bokusasazwa kwe-optical kwindawo, okanye ziguqule ukukhanya okungenangqiqo kube kukukhanya okuhambelanayo phantsi kolawulo lwesignali eziqhutywa ngombane okanye ezinye ezitshintsha ngokuhamba kwexesha. Ngenxa yale mpawu, ingasetyenziswa njengeyunithi yokwakha okanye isixhobo esibalulekileyo ekucutshungulweni kolwazi lwe-optical ngexesha langempela, ukubalwa kwe-optical kunye neenkqubo zenethiwekhi ye-optical neural.

Imodulator yokukhanya kwendawo inokwahlulwahlulwa ngohlobo lokukhanya kunye nohlobo lokudlulisela ngokwendlela eyahlukileyo yokufunda yokukhanya. Ngokwesignali yokulawula yokufaka, inokwahlulwahlulwa ibe yidilesi ye-optical (OA-SLM) kunye nedilesi yombane (EA-SLM).

Ukusetyenziswa kwe-modulator yokukhanya kwendawo

Ivalvu yokukhanya yekristale yolwelo esebenzisa ukukhanya - ukuguqulwa okuthe ngqo kokukhanya, ukusebenza kakuhle okuphezulu, ukusetyenziswa kwamandla aphantsi, isantya esikhawulezayo, umgangatho olungileyo. Ingasetyenziswa kakhulu kwi-optical computing, ukuqondwa kweepateni, ukucubungula ulwazi, ukubonisa kunye nezinye iinkalo, kwaye inamathuba amaninzi okusetyenziswa.

I-Spatial light modulator sisixhobo esibalulekileyo kwiinkalo ze-optical zanamhlanje ezifana nokucubungula ulwazi lwe-optical ngexesha langempela, i-adaptive optics kunye ne-optical computation. Kakhulu, ukusebenza kwe-spatial light modulators kumisela ixabiso elisebenzayo kunye namathuba ophuhliso lwala macandelo.

Iinkqubo eziphambili, umzobo kunye nokubonisa, ukwahlulwahlulwa kwemisebe, ukubumba imisebe yelaser, ukuguquguquka kwe-coherent wavefront, ukuguquguquka kwesigaba, ii-optical tweezers, ukuboniswa kweholographic, ukwakheka kwe-laser pulse, njl.
