Mabda'a iyo horumarinta curiyeyaasha indhaha ee kala duwan

Cunsurka indhaha ee Diffraction waa nooc ka mid ah walxaha indhaha oo leh hufnaan sare oo kala duwan, kaas oo ku saleysan aragtida kala-duwanaanta ee hirarka iftiinka oo adeegsada naqshadeynta kombuyuutar-ku-caawinta iyo habka wax-soo-saarka chip-ka-soo-saarka si loo dhejiyo tallaabada ama qaab-dhismeedka gargaarka joogtada ah ee substrate (ama dusha sare) Qalabka indhaha ee dhaqameed).Walxaha indhaha ee kala firdhisan waa dhuuban, iftiin, cabbir yar, oo leh hufnaan sare oo kala duwanaansho ah, heerar kala duwan oo nashqadaynta xorriyadda, xasilloonida kulaylka wanaagsan iyo sifooyinka kala firidhsan ee gaarka ah.Waxay yihiin qaybo muhiim ah oo ka mid ah qalabyo badan oo indhaha ah.Tan iyo diffraction had iyo jeer waxay keenaysaa in xaddidaadda xallinta sare ee nidaamka indhaha, optics dhaqameed had iyo jeer isku dayaan in ay ka fogaadaan saamaynta xun ee ay keento saamaynta diffraction ilaa 1960, la ikhtiraacida iyo wax soo saarka guul ee holography analog iyo hologram kombiyuutarka iyo sidoo kale jaantuska wajiga sababay a isbedel weyn xagga fikradda.Sanadihii 1970-meeyadii, in kasta oo tignoolajiyada hologram-ka kumbuyuutarka iyo jaantuska wejiga uu noqday mid aad iyo aad u qumman, haddana way adkeyd in la sameeyo walxaha qaab-dhismeedka hyperfine ee leh hufnaanta sare ee hirarka dhaadheer ee infrared ee muuqda iyo kuwa u dhow, taas oo xaddidaysa adeegsiga la taaban karo ee kala duwanaanshaha walxaha indhaha ee kala duwan. .Sanadihii 1980-aadkii, koox cilmi baaris ah oo uu hogaaminayay WBVelkamp oo ka socday MIT Lincoln Laboratory ee dalka Mareykanka ayaa markii ugu horeysay soo bandhigtay tignoolajiyada lithography ee wax soo saarka VLSI ee soo saarista qaybaha indhaha ee kala duwan, waxayna soo jeediyeen fikradda "binary optics".Taas ka dib, habab cusub oo processing cusub sii wadaan in ay soo baxaan, oo ay ku jiraan wax soo saarka ee tayo sare leh iyo qaybaha kala duwan ee indhaha.Sidaas awgeed waxay si weyn kor ugu qaadday horumarinta walxaha indhaha ee kala duwan.

Hufnaanta kala duwanaanshaha curiyaha indhaha ee kala duwan

Hufnaanta Diffractive waa mid ka mid ah tusmooyinka muhiimka ah ee lagu qiimeeyo curiyayaasha indhaha ee kala duwan iyo hababka indhaha ee isku dhafan ee leh curiyayaasha indhaha kala duwan.Ka dib marka iftiinku dhex maro curiyaha indhaha ee kala duwan, amarro kala duwanaansho badan ayaa la soo saari doonaa.Guud ahaan, kaliya iftiinka amarka kala-duwanaanta ugu weyn ayaa fiiro gaar ah loo leeyahay.Iftiinka amarrada kale ee kala-duwanaanshaha waxay ku sameyn doonaan iftiin khaldan oo ku saabsan diyaaradda sawirka ee amarka kala-duwanaanta ugu weyn waxayna yareyneysaa isbarbardhigga diyaaradda sawirka.Sidaa darteed, hufnaanta kala-duwanaanta curiyaha indhaha ee kala-duwanaanta ayaa si toos ah u saameeya tayada sawirka ee curiyaha indhaha kala duwan.

Horumarinta curiyeyaasha indhaha ee kala duwan

Iyada oo ay ugu wacan tahay curiyaha indhaha ee kala duwan iyo mawjada hore ee kontoroolka dabacsan, nidaamka indhaha iyo aaladda ayaa u koraya iftiin, la yareeyey oo isku dhafan.Ilaa 1990-meeyadii, daraasadda curiyeyaasha indhaha ee kala duwan ayaa noqday safka hore ee goobta indhaha.Qaybahaan waxaa si weyn loogu isticmaali karaa hagaajinta wavefront laser, sameynta profile beam, koronto-dhaliye array, isku xirnaanta indhaha, xisaabinta isbarbardhigga indhaha, isgaarsiinta satellite-ka iyo wixii la mid ah.
