Muraayadaha sawiridaayaa si weyn loogu isticmaalaa AOI, kormeerka daabacaadda, kormeerka dharka aan toliyaha lahayn, kormeerka maqaarka, kormeerka jidka tareenka, baarista iyo kala soocida midabka iyo warshadaha kale.Maqaalkani waxa uu horudhac u keenayaa muraayadaha sawir-qaadista.

Hordhac Lens Scan Line

1) Fikradda lenska sawir-qaadista:

Lens-ka laynka ee CCD waa muraayada FA-ga ee wax-qabadka sare leh ee kamaradaha taxanaha dareemayaasha ee u dhigma cabbirka sawirka, cabbirka pixel, waxaana lagu dabaqi karaa baaritaanno kala duwan oo sax ah.

2) Astaamaha muraayada iskaanka ee laynka:

1. Si gaar ah loogu talagalay codsiyada iskaanka ee xallinta sare leh, ilaa 12K;

2. Meesha ugu sarraysa ee la beegsanayo sawir-qaadista waa 90mm, iyadoo la isticmaalayo kamarad sawir xariiq dheer;

3. Xallinta sare, cabbirka ugu yar ee pixel ilaa 5um;

4. Heerka qallooca hooseeya;

5. Weynaynta 0.2x-2.0x.

Tixgelinta Doorashada Lens Scan Line

Waa maxay sababta aan u tixgelinno doorashada muraayadda marka la dooranayo kamarad?Kaamirooyinka iskaanka ee khadka caadiga ah waxay hadda leeyihiin xallinta 1K, 2K, 4K, 6K, 7K, 8K, iyo 12K, iyo cabbirada pixel ee 5um, 7um, 10um, iyo 14um, si cabbirka chip uu u dhexeeyo 10.240mm (1Kx10um) ilaa 86.016mm (12Kx7um) way kala duwan tahay.

Sida iska cad, Interface-ka C aad ayuu uga fog yahay buuxinta shuruudaha, sababtoo ah interface-ka C wuxuu ku xiri karaa oo keliya jajabyada leh cabbirka ugu sarreeya ee 22mm, taas oo ah 1.3 inji.Isku xirka kamarado badan ayaa ah F, M42X1, M72X0.75, iwm

1) Weyneynta indhaha (β, Weyneynta)

Marka xallinta kamarada iyo cabbirka pixel la go'aamiyo, cabbirka dareemayaasha waa la xisaabin karaa;cabbirka dareemaha ee loo qaybiyay goobta aragtida (FOV) waxay la mid tahay weynaynta indhaha.β=CCD/FOV

2) Interface (Buur)

Inta badan waxaa jira C, M42x1, F, T2, Leica, M72x0.75, iwm. Kadib xaqiijinta, waxaad ogaan kartaa dhererka interface u dhigma.

3) Masaafada Flange

Diirada dhabarka waxaa loola jeedaa masaafada u jirta diyaaradda interface camera ilaa chip-ka.Waa halbeeg aad u muhiim ah waxaana go'aamiya soo saaraha kamarada iyadoo loo eegayo naqshadeeda dariiqa indhaha.Kamaradaha soo saarayaasha kala duwan, xitaa leh interface isku mid ah, ayaa laga yaabaa inay leeyihiin diiradda dhabarka oo kala duwan.

4) MTF

Marka la eego weyneynta indhaha, is-dhexgalka, iyo diiradda gadaal, masaafada shaqada iyo dhererka giraanta wadajirka ayaa la xisaabin karaa.Kadib xulashada kuwan, waxaa jira xiriir kale oo muhiim ah, kaas oo ah in la arko haddii qiimaha MTF uu ku filan yahay?Ingineero badan oo aragga ma fahmaan MTF, laakiin muraayadaha-dhamaadka sare, MTF waa in loo isticmaalo si loo cabbiro tayada indhaha.

MTF waxa ay dabooshaa macluumaad badan sida isbarbardhigga, xallinta, soo noqnoqoshada boosaska, aberration chromatic, iwm., waxayna si faahfaahsan u muujisaa tayada indhaha ee xarunta iyo cidhifka muraayadda.Ma aha oo kaliya masaafada shaqada iyo aragtida aragtida ayaa buuxinaysa shuruudaha, laakiin isbarbardhigga cidhifyadu kuma fiicna, laakiin sidoo kale haddii la doorto muraayadda xallinta sare waa in dib loo eego.
