Yini i-spatial light modulator?

I-Spatial Light Modulator isho ukuthi ngaphansi kokulawulwa okusebenzayo, ingaguqula amapharamitha athile wenkambu yokukhanya ngama-molecule we-liquid Crystal, aguqule ukuguqulwa kwenkomba yokukhanya, ukuguqula isimo esithile sokushintshana, ukuze ubhalise imininingwane ethile kwi-Light Wave Sokushintsha. Ingalayisha kalula imininingwane ibe yindawo eyodwa noma ezimbili ezibonakalayo ze-Optical field, futhi isebenzise izinzuzo ze-Wide Band of Light of Light, ukucubungula okuhambisanayo okuningi nokunye ukucubungula imininingwane elayishwe ngokushesha. Kuyingxenye esemqoka yokucutshungulwa kwemininingwane yesikhathi sangempela, ukuxhumana kwe-Optical interconconction, i-Optical Computing nezinye izinhlelo.

Umgomo osebenzayo we-Spatial Light Modulator

Ngokuvamile, i-spatial Light Modulator iqukethe amayunithi ama-Undependent amaningana, ahlelwe ngokulandelana okunezinhlangothi ezimbili noma ezimbili. Iyunithi ngalinye lingathola ukulawulwa kwesiginali ye-Optical Signal noma isiginali kagesi ngokuzimela, futhi sishintshe izakhiwo zalo ezibonakalayo ngokuya ngesiginali, ukuze kuguqulwe igayidi elikhanyayo elikhanyiselwe kulo. Amadivaysi anjalo angashintsha i-amplitude noma ubukhulu, isigaba, isimo se-polarization kanye nokusatshalaliswa kokusatshalaliswa kwe-optical esikhaleni, noma ukuguqula ukukhanya okungafinyeleleki kube ukukhanya okulungiselelwe kagesi noma ezinye izibonakaliso eziguqukayo ngesikhathi. Ngenxa yale mpahla, ingasetshenziswa njengeyunithi yokwakha noma idivaysi esemqoka ekusebenzeni kolwazi lwesikhathi sangempela, ukuhlanganiswa kwe-Optical ne-Optical Neural Network System.

I-spatial Light Modulator ingahlukaniswa ibe uhlobo lokubonisa nohlobo lokuhambisa ngokuya ngemodi yokufunda ehlukile yokukhanya. Ngokwesiginali yokulawula yokufaka, ingahlukaniswa i-Optical Poliction (OA-SLM) kanye nokwakheka kukagesi (EA-SLM).

Ukusetshenziswa kwe-Spatial Light Modulator

I-Liquid Crystal Light Valve ekhanyayo isebenzisa ukukhanya - Ukuguqulwa okuqondile okukhanyayo, ukusebenza kahle okuphezulu, ukusetshenziswa okuphansi kwamandla, isivinini esisheshayo, ikhwalithi enhle. Ingasetshenziswa kabanzi kwikhompyutha ye-optical, ukuqashelwa kwephethini, ukucubungula imininingwane, ukuboniswa kanye nezinye izinkambu, futhi kunamathemba wohlelo lokusebenza olubanzi.

I-Spatial Light Modulator iyithuluzi elisemqoka emasimini abonakalayo wesimanje afana nokucubungula imininingwane yesikhathi sangempela, ama-adaptive e-Optics kanye ne-Optical Complation. Ngokwezinga elikhulu, ukusebenza kwama-spatial light modulators inquma inani elisebenzayo kanye namathemba okuthuthuka kwalezi zinkambu.

Izicelo ezisemqoka, ukucabanga nokuqagela, ukuhlukaniswa kwe-beam, i-laser beam ekwakheni, ukuguquguquka okubumbene, ukuguquguquka kwesigaba, ukuguqulwa kwesigaba, ukuguqulwa kwe-optical, ukuhlukaniswa kwe-loverographic, ukubumba kwe-laser pulse, njll.
