Iyo yekucheka-kumucheto kunyorera mune optics inotungamirwa neoptical modulators

Nheyo yeoptical modulationhaina kuoma. Iyo inonyanya kuzadzisa modulation yeamplitude, chikamu, polarization, refractive index, absorption rate uye mamwe maitiro echiedza kuburikidza nekunze kwekusimudzira, kunyatso kudzora chiratidzo chemaziso, sekugonesa mafoto kutakura uye kutumira ruzivo. Zvinhu zvakakosha zve commonelectro-optic modulatorinosanganisira zvikamu zvitatu: electro-optic crystals, electrodes, uye optical elements. Munguva yekuchinja kwechiedza, izvo zviri mu optical modulator zvinoshandura iyo refractive index, absorption rate uye zvimwe zvivakwa pasi pesimba rekunze stimuli (senge minda yemagetsi, minda yekurira, shanduko yekupisa kana masimba emagetsi), zvichikanganisa hunhu hwemafotoni sezvavanopfuura nepakati pezvinhu, sekudzora kupararira kwemaitiro, chikamu chechiedza (amplitu). Iyo electro-optical crystal ndiyo musimboti weiyoOptical modulator, ine mutoro wekupindura kune shanduko mumunda wemagetsi uye kushandura iyo refractive index. Electrodes anoshandiswa kuisa minda yemagetsi, nepo optical components senge polarizers uye waveplates anoshandiswa kutungamira uye kuongorora mafotoni anopfuura nepakati pekristaro.

Frontier Zvishandiso mune Optics

1.Holographic projection uye kuratidza teknolojia

Mune holographic fungidziro, kushandiswa kwespatial optical modulators kunyatsogadzirisa chiitiko chemwenje masaisai anogona kugonesa masaisai emwenje kupindira uye kukanganisa neimwe nzira, achigadzira yakaoma mwenje kugovera munda. Semuenzaniso, SLM yakavakirwa pakristaro yemvura kana DMD inogona kugadzirisa mhinduro yepixel yega yega, kushandura chimiro chemufananidzo kana maonero munguva chaiyo, zvichibvumira vataridzi kuti vatarise matatu-dimensional maitiro echifananidzo kubva kumakona akasiyana.

2.Optical data kuchengetedza munda

Optical data kuchengetedza tekinoroji inoshandisa yakakwirira-frequency uye yakakwirira-simba maitiro echiedza kukodha uye decode ruzivo kuburikidza nechaiyo mwenje modulation. Iyi tekinoroji inotsamira pakutonga chaiko kwemafungu emwenje, kusanganisira kugadziridzwa kweamplitude, chikamu uye polarization state, kuchengetedza data pane midhiya senge optical discs kana holographic kuchengetedza zvinhu. Optical modulators, kunyanya spatial optical modulators, inoita basa rakakosha mukubvumira kunyatso kudzora kwekutarisa pamusoro pekuchengetedza uye kuverenga maitiro.

Padanho rekuona, mafotoni akafanana nevatambi vakanaka, vachitamba zvine nyasha ku "melody" yezvinhu zvakaita sekristaro, makristasi emvura uye optical fibers. Ivo vanogona kushandura zvine mutsindo nzira, kumhanya, uye nekukasira kupfeka "zvipfeko zvemavara" zvakasiyana, vachishandura mafambiro avo uye rhythm, uye vachiratidza kuita kunoshamisa mushure meumwe. Uku kunyatso kudzora kwemafotoni ndiyo chaiyo kiyi yemashiripiti kune yekucheka-kumucheto kweramangwana optical tekinoroji, zvichiita kuti nyika yemaziso izere nezvisingaperi zvingangoitika.
