Iibinta tooska ah ee warshadda si adag loo cabbiray muraayadaha muraayadaha indhaha ee priism-ka.

Sharaxaad Gaaban:

Prism waa curiye indhaha u roga iftiinka iyadoo la eegayo xagasha gaarka ah ee u dhexeeya iftiinka baxaya iyo iftiinka dhacdada.Jidka indhaha, prismku wuxuu bedeli karaa xagasha u dhaxaysa iftiinka baxaya iyo iftiinka dhacdada (sida 90 °, 180, iwm.), wuxuu dejiyaa iftiinka oo beddelaa jihada sawirka.

Prism, waa shay daah-furan oo ay ku wareegsan yihiin laba diyaaradood oo is-goysyada ah oo aan is-bar-bar-bar-dhig lahayn, oo loo isticmaalo kala-goynta ama kala-firdhinta iftiinka iftiinka.Prism waa polyhedron ka samaysan walxo hufan (sida galaas, crystal, iwm.).Waxa si weyn loogu isticmaalaa aaladaha indhaha.Prisms waxa loo qaybin karaa dhawr nooc iyadoo loo eegayo hantidooda iyo isticmaalkooda.Tusaale ahaan, aaladaha spectral-ka, "prism-ka kala firdhisan" ee kala saara iftiinka isku dhafan ee spectrum ayaa inta badan loo isticmaalaa sida prism siman;Marka la eego periscope-ka, telescope-ka binocular iyo aaladaha kale, beddelaadda jihada iftiinka si loo hagaajiyo booskiisa sawir-qaadista waxaa loo yaqaan "wadarta milicsiga prism", kaas oo guud ahaan qaata priism xagal qumman.

Qeexid:

Prism waa polyhedron ka samaysan walxo hufan (sida galaas, crystal, iwm.).Waxa si weyn loogu isticmaalaa aaladaha indhaha.Prisms waxa loo qaybin karaa dhawr nooc iyadoo loo eegayo hantidooda iyo isticmaalkooda.Tusaale ahaan, aaladaha spectral-ka, "prism-ka kala firdhisan" ee kala saara iftiinka isku dhafan ee spectrum ayaa inta badan loo isticmaalaa sida prism siman;Marka la eego periscope-ka, telescope-ka binocular iyo aaladaha kale, beddelaadda jihada iftiinka si loo hagaajiyo booskiisa sawir-qaadista waxaa loo yaqaan "wadarta milicsiga prism", kaas oo guud ahaan qaata priism xagal qumman.

Hel:

Newton waxa uu daahfuray kala firdhisanaanta iftiinka sannadkii 1666-kii, Shiinuhuna arrimahan ajaaniibta ayay kaga horeeyeen.Qarnigii 10-aad ee AD, Shiineysku waxay ugu yeereen crystal transparent dabiiciga ah ka dib markii ay iftiimiyeen iftiinka qoraxda "Wuguang stone" ama "Guangguang stone", waxayna ogaadeen in "Iftiinka iftiinka qoraxda, uu noqdo shan midab sida neon".Tani waa fahamka ugu horreeya ee kala firdhisanaanta iftiinka adduunka.Waxay muujinaysaa in dadku ay ka xoreeyeen kala daadsanaanta iftiinka sirta oo ay ogaadaan in ay tahay arrin dabiici ah, taas oo ah horumar weyn oo xagga fahamka iftiinka ah.Waa 700 oo sano ka hor fahamkii Newton in iftiinka cad uu ka kooban yahay todobo midab isagoo u qaybinaya iftiinka qoraxda todobo midab iyada oo loo marayo prism.

Kala soocida:

Polyhedron oo ka samaysan walxo daah-furan ayaa ah curiye indhaha oo muhiim ah.Diyaaradda uu iftiinku ka soo galo ama ka soo baxo waxa la yidhaa dhinac, dayuurada oo dhinac u taaganna waxa loo yaqaan qaybta wayn.Marka loo eego qaabka qaybta ugu muhiimsan, waxa loo qaybin karaa saddex geesood, xagal toosan, laba geesood, iwm.Xagasha ay ku jiraan waxaa lagu magacaabaa xagasha sare, diyaaradda ka soo horjeeda xagasha sare waa dusha hoose.Marka loo eego sharciga dib-u-celinta, iftiinku wuxuu dhex maraa prism oo laba jeer u leexdaa xagga hoose.Xagasha lagu daray Q ee u dhaxaysa iftiinka baxaya iyo iftiinka shilka waxaa loo yaqaan xagasha leexinta.Cabbirkeeda waxaa lagu go'aamiyaa index refractive n iyo xaglaha dhacdada I ee dhexdhexaadka priismka.Marka aan go'o, mowjadaha dhaadheer ee iftiinka ayaa leh xaglo leexin oo kala duwan.Iftiinka muuqda, xagasha leexinta ugu weyn waa iftiin guduudan kan ugu yarna waa iftiin cas.

Shaqada:

Nolosha casriga ah, priism waxaa si weyn loogu isticmaalaa qalabka dhijitaalka ah, sayniska iyo farsamada, qalabka caafimaadka iyo qaybaha kale.
Qalabka dijitaalka ah ee caadiga ah: kamarad, telefishin wareeg ah, mashruuc, kamarad dijital ah, kamarad dhijitaal ah, lens CCD iyo qalabyo kala duwan; Sayniska iyo tignoolajiyada: telescope, mikroskoob, cabbirka heerka, qalabka faraha, aragga qoriga, beddelaha qoraxda iyo qalabyada cabbira ee kala duwan; Qalabka caafimaadka: cystoscope, gastroscope iyo qalabka daaweynta laser kala duwan

Astaamaha

K9 Crystal Optical Cube ama Qalabka Infrared ee X-Cube Prism
Dichroic priism waa prism ka soo baxa iftiinka oo u kala qaybiya laba laydh oo dhererkoodu kala duwan yahay (midab).
A drichroic priism Assembly waxa ay isku daraa laba prisms dichroic si ay u kala qaybiyaan sawirka 3 midab, sida caadiga ah sida casaan, cagaar iyo buluug ee qaabka midabka RGB.Badanaa waxay ka samaysan yihiin hal ama in ka badan oo muraayado ah oo leh dahaar indho-indhayn ah oo si xushmad leh uga tarjumaya ama gudbiya iftiinka iyadoo ku xidhan hirarka iftiinka.Taasi waa, meelo gaar ah oo ku dhex jira priism-ka waxay u dhaqmaan sidii filtarrada dichroic.Kuwaas waxaa loo isticmaalaa sida kala qaybiyayaal alwaax ah oo ku jira qalabyo badan oo indhaha ah

Faa'iidada

Nuugista iftiinka ugu yar, nalka intiisa badan waxaa loo jiheeyaa mid ka mid ah laydhka wax soo saarka.
Kala soocida midabka ka wanaagsan inta badan filtarrada kale.
Way fududahay in la sameeyo isku-dar kasta oo xargaha baaska ah.
Uma baahna is dhexgal midab ah ( demosaicing) oo sidaas awgeed waxay ka fogaataa dhammaan farshaxanada midabka beenta ah ee sida caadiga ah lagu arko sawirada la sawiray.
