Codsiyada cidhiidhiga ah ee muraayadaha indhaha ee ay hoggaamiyaan modulators indhaha

Mabda'a ahhabaynta indhahamaaha mid adag. Waxay inta badan ku guulaysataa habaynta baaxadda, wajiga, polarization, index refractive, heerka nuugista iyo sifooyinka kale ee iftiinka iyada oo loo marayo kicinta dibadda, si sax ah loo xakameeyo calaamadda indhaha, sida awoodsiinta photons inay qaadaan oo gudbiyaan macluumaadka. Qaybaha aasaasiga ah ee caadiga ahmodulator-ka-elektroonigawaxaa ku jira saddex qaybood: crystals electro-optic, electrodes, iyo element indhaha. Inta lagu guda jiro habka habaynta iftiinka, walxaha ku jira modulator-ka indhaha ayaa isbeddelaya index refractive, heerka nuugista iyo sifooyinka kale ee saamaynta kicinta dibadda (sida beeraha korantada, goobaha dhawaaqa, isbeddellada kulaylka ama xoogagga farsamada), taas oo saameynaysa habdhaqanka photons marka ay dhex maraan walxaha, sida xakamaynta sifooyinka faafinta iftiinka (balaadhka, wejiga, iwm.). Crystal-optical crystal waa udub dhexaadkamodulator indhaha, oo mas'uul ka ah ka jawaabista isbeddellada ku yimaada goobta korontada iyo beddelka tusmaheeda dib-u-celinta. Electrodes waxaa loo isticmaalaa in lagu dabaqo meelaha korantada, halka qaybaha indhaha sida polarizers iyo waveplates loo isticmaalo in lagu hago laguna falanqeeyo sawir-qaadayaasha dhex mara crystal.

Codsiyada Frontier ee Optics

1.Holographic saadaalinta iyo tignoolajiyada bandhigga

Saadaasha holographic, isticmaalka modulators indhaha si ay si fiican u habeeyaan mowjadaha iftiinka dhacdada waxay awood u siin karaan hirarka iftiinka inay farageliyaan oo ay u kala baxaan si gaar ah, samaynta qaybinta iftiinka adag. Tusaale ahaan, SLM oo ku salaysan crystal dareere ama DMD waxay si firfircoon u hagaajin kartaa jawaabta indhaha ee pixels kasta, waxay beddeli kartaa nuxurka sawirka ama aragtida wakhtiga dhabta ah, taas oo u oggolaanaysa daawadayaasha inay u fiirsadaan saamaynta saddex-geesoodka ah ee sawirka xaglo kala duwan.

2.Optical kaydinta xogta

Tiknoolajiyada kaydinta xogta indhaha ayaa adeegsata soo noqnoqoshada sare iyo sifooyinka tamarta sare ee iftiinka si ay u codeeyaan oo u dejiyaan macluumaadka iyada oo loo marayo qaabaynta iftiinka saxda ah. Tignoolajiyadani waxay ku tiirsan tahay xakamaynta saxda ah ee hirarka iftiinka, oo ay ku jiraan hagaajinta baaxadda, marxaladda iyo gobolka polarization, si loo kaydiyo xogta warbaahinta sida saxanadaha indhaha ama agabka kaydinta holographic. Modulators indhaha, gaar ahaan modulators indhaha, ayaa door muhiim ah ka ciyaara u oggolaanaya in si sax ah loo xakameeyo habka kaydinta iyo akhrinta.

Marxaladda indhaha, sawir-qaadayaashu waxay la mid yihiin qoob-ka-cayaarayaasha quruxda badan, oo si xarrago leh ugu qoob-ka-ciyaara "laxanka" qalabka sida kiristaalo, kiristaalo dareere ah iyo fiilooyinka indhaha. Waxay si xarrago leh u beddeli karaan jihada, xawaaraha, iyo xitaa isla markiiba gashan karaan "dhar midab leh" oo kala duwan, beddelaan dhaqdhaqaaqooda iyo laxanka, waxayna soo bandhigayaan hal waxqabad oo cajiib ah ka dib. Kontoroolka saxda ah ee sawir-qaadista ayaa si sax ah u ah furaha sixirka ee goynta tignoolajiyada mustaqbalka ee indhaha, taas oo ka dhigaysa adduunka indhaha oo ay ka buuxaan fursado aan xadidnayn.
