Porogaramu zigezweho muri optique ziyobowe na modulator z'amajwi

Ihame ryamodulation y'amajwintabwo bigoye. Igera ahanini ku ihinduka rya amplitude, phase, polarization, refractive index, absorption rate n'ibindi biranga urumuri binyuze mu bintu byo hanze, kugira ngo igenzure neza ikimenyetso cy'urumuri, nko gutuma fotoni zitwara kandi zigatanga amakuru. Ibice by'ibanze by'ikintu gihuriwehomodulator y'amashanyarazi n'amataraharimo ibice bitatu: kristu za electro-optic, electrodes, n'ibintu by'urumuri. Mu gihe cyo guhindura urumuri, ibikoresho biri muri modulator y'urumuri bihindura igipimo cyabyo cyo kurekura urumuri, igipimo cyo kwinjiza urumuri n'ibindi binyabupfura bitewe n'ibintu byo hanze (nk'amashanyarazi, amajwi, impinduka z'ubushyuhe cyangwa imbaraga za mekanike), bityo bigira ingaruka ku myitwarire ya fotoni mu gihe zinyura mu bikoresho, nko kugenzura imiterere y'urumuri (amplitude, phase, polarization, nibindi). Kristale ya electro-optical ni yo shingiro ry'urumurimodulator y'izuba, ishinzwe gusubiza impinduka mu bushobozi bw'amashanyarazi no guhindura imiterere yayo ya refractive. Electrodes zikoreshwa mu gukoresha amashanyarazi, mu gihe ibice by'urumuri nka polarizers na waveplates bikoreshwa mu kuyobora no gusesengura fotoni zinyura muri kristu.

Porogaramu zo mu rwego rwa Frontier muri Optics

1. Ikoranabuhanga ryo kwerekana no kwerekana ishusho ya Holographic

Mu gupima holographic, gukoresha modulators z’urumuri mu buryo bwo guhindura neza imiraba y’urumuri ishobora gutuma imiraba y’urumuri ibangamira kandi igahindagurika mu buryo bwihariye, bigatuma urumuri rukwirakwira mu buryo bugoye. Urugero, SLM ishingiye kuri crystal y’amazi cyangwa DMD ishobora guhindura uburyo urumuri rugaragara rwa buri pixel, igahindura ibikubiye mu ishusho cyangwa icyerekezo mu gihe nyacyo, bigatuma abayireba babona ingaruka z’ishusho mu buryo butatu mu mpande zitandukanye.

2. Ahantu ho kubika amakuru y'urumuri

Ikoranabuhanga ryo kubika amakuru y’urumuri rikoresha imiterere y’urumuri ifite imbaraga nyinshi n’ingufu nyinshi kugira ngo rishyire mu buryo bunoze kandi risobanure amakuru binyuze mu guhindura urumuri neza. Iri koranabuhanga rishingiye ku kugenzura neza imiraba y’urumuri, harimo no guhindura imiterere y’ubwinshi bw’amajwi, imiterere y’ibyiciro n’imiterere y’impinduka, kugira ngo ribike amakuru ku byuma nka disiki z’urumuri cyangwa ibikoresho byo kubika holographic. Ibikoresho by’urumuri, cyane cyane ibikoresho by’urumuri bifite uruhare runini mu gutuma habaho kugenzura neza uburyo bwo kubika no gusoma amakuru.

Ku rubyiniro rw'amatara, fotoni zimeze nk'ababyinnyi beza cyane, babyina neza bakurikije "injyana" y'ibikoresho nka kristu, kristu z'amazi n'imigozi y'amatara. Bashobora guhindura icyerekezo, umuvuduko, ndetse bakanambara "imyenda y'amabara" atandukanye, bagahindura imikorere yabo n'imivugirwe yabo, kandi bagatanga imikorere itangaje ku yindi. Uku kugenzura neza fotoni ni ingenzi cyane ku ikoranabuhanga rigezweho ry'amatara, bigatuma isi y'amatara yuzuyemo amahirwe atagira ingano.
