Porogaramu igezweho muri optique iyobowe na optique modulator

Ihame ryaGuhindurantabwo bigoye. Igera cyane cyane kuri modulisiyo ya amplitude, icyiciro, polarisiyasi, indangagaciro zivunika, igipimo cyo kwinjiza nibindi biranga urumuri binyuze mubitera hanze, kugenzura neza ibimenyetso bya optique, nko gufasha fotone gutwara no kohereza amakuru. Ibice byibanze bigize rusangeamashanyarazi ya optiqueshyiramo ibice bitatu: kristu ya electro-optique, electrode, nibintu bya optique. Mugihe cyoguhindura urumuri, ibikoresho biri mumashanyarazi ya optique bihindura indangagaciro zayo zivunika, igipimo cyo kwinjiza nibindi bintu biterwa ningaruka ziva hanze (nkumuriro wamashanyarazi, imirima y amajwi, impinduka zumuriro cyangwa imbaraga za mashini), bityo bikagira ingaruka kumyitwarire ya fotone nkuko inyura mubikoresho, nko kugenzura ibiranga ikwirakwizwa ryumucyo (amplitude, phase, polarisation, nibindi). Electro-optique kristu niyo ntandaro yamoderi nziza, ashinzwe gusubiza impinduka mumashanyarazi no guhindura indangagaciro zayo. Electrode ikoreshwa mugukoresha amashanyarazi, mugihe ibice bya optique nka polarizeri na flake byifashishwa mu kuyobora no gusesengura fotone inyura muri kristu.

Imipaka ikoreshwa muri optique

1.Holographic projection no kwerekana tekinoroji

Muri holographic projection, gukoresha modulatrice optique ya modulatrice kugirango ihindure neza ibyabaye urumuri rwumucyo birashobora gutuma urumuri rwumucyo rwivanga kandi rugatandukana muburyo bwihariye, rukora urumuri rugoye rwo gukwirakwiza. Kurugero, SLM ishingiye kumazi ya kirisiti cyangwa DMD irashobora guhindura byimazeyo igisubizo cyiza cya buri pigiseli, guhindura ibishusho cyangwa icyerekezo mugihe nyacyo, bigatuma abayireba bareba ingaruka-eshatu zishusho ziva muburyo butandukanye.

2.Umwanya wo kubika amakuru neza

Ikoreshwa rya optique yo kubika amakuru ikoresha umurongo-mwinshi hamwe ningufu nyinshi ziranga urumuri kugirango ushireho kandi ushushanye amakuru ukoresheje urumuri rwuzuye. Iri koranabuhanga rishingiye ku kugenzura neza imiraba y’umucyo, harimo no guhindura amplitude, icyiciro na polarisiyasi, kugirango ibike amakuru ku bitangazamakuru nka disiki ya optique cyangwa ibikoresho byo kubika holographique. Modulatrice optique, cyane cyane moderi ya optique ihindagurika, igira uruhare runini mukwemerera kugenzura neza neza ububiko no gusoma.

Kuri optique, fotone ni nkababyinnyi beza, babyina neza kuri "melody" yibikoresho nka kristu, kristu y'amazi na fibre optique. Barashobora guhindura muburyo bwiza icyerekezo, umuvuduko, ndetse bagahita bambara "imyambarire yamabara" itandukanye, bagahindura ingendo zabo nindirimbo zabo, kandi bakerekana imikorere idasanzwe kurindi. Uku kugenzura neza fotone nukuri urufunguzo rwubumaji rwo guca inyuma tekinoroji ya optique izaza, bigatuma isi optique yuzuye ibishoboka bitagira akagero.
