Iskena amalensizisetshenziswa kakhulu ku-AOI, ukuhlolwa kokuphrinta, ukuhlolwa kwendwangu engalukiwe, ukuhlolwa kwesikhumba, ukuhlolwa kukamzila wesitimela, ukuhlola nokuhlunga imibala nezinye izimboni. Lesi sihloko siletha isingeniso kumalensi wokuskena komugqa.

Isingeniso Selensi Yokuskena Ngomugqa

1) Umqondo welensi yokuskena komugqa:

Ilensi ye-CCD yomugqa womugqa iyilensi ye-FA esebenza kakhulu yamakhamera ochungechunge lwezinzwa ezihambisana nosayizi wesithombe, usayizi wamaphikseli, futhi ingasetshenziswa ekuhlolweni okunembayo okuphezulu.

2) Izici ze-lens yokuskena komugqa:

1. Idizayinelwe ngokukhethekile izinhlelo zokusebenza zokuskena ezinokulungiswa okuphezulu, kufika ku-12K;

2. Ubukhulu obuhambisanayo bethagethi yendawo ehlosiwe yi-90mm, kusetshenziswa ikhamera yokuskena yomugqa omude;

3. Ukulungiswa okuphezulu, ubuncane besayizi yephikseli kufika ku-5um;

4. Izinga lokuhlanekezela eliphansi;

5. Ukukhulisa 0.2x-2.0x.

Okucatshangwayo Ngokukhetha Ilensi Yokuskena Ulayini

Kungani kufanele sicabangele ukukhetha kwamalensi lapho sikhetha ikhamera? Amakhamera omugqa ojwayelekile wokuskena okwamanje anezinqumo ezingu-1K, 2K, 4K, 6K, 7K, 8K, no-12K, nosayizi wamaphikseli angu-5um, 7um, 10um, no-14um, ukuze usayizi we-chip usukela ku-10.240mm (1Kx10um) kuye ku-86.016mm (12Kx7um) kuyahlukahluka.

Ngokusobala, i-interface ye-C isekude ukuhlangabezana nezidingo, ngoba i-interface ye-C ingaxhuma kuphela ama-chips ngosayizi omkhulu we-22mm, okungama-intshi angu-1.3. I-interface yamakhamera amaningi i-F, M42X1, M72X0.75, njll. I-interface ye-lens ehlukene ihambisana nokugxila okuhlukile emuva (Ibanga le-Flange), elinquma ibanga lokusebenza le-lens.

1) Ukukhulisa okubonakalayo(β, Ukukhulisa)

Uma ukulungiswa kwekhamera nosayizi wephikseli sekunqunyiwe, usayizi wezinzwa ungabalwa; usayizi wezinzwa ohlukaniswe umkhakha wokubuka(FOV) ulingana nokukhuliswa kwe-optical. β=CCD/FOV

2) Isixhumi esibonakalayo(Mount)

Kukhona ikakhulukazi C, M42x1, F, T2, Leica, M72x0.75, njll. Ngemva kokuqinisekisa, ungakwazi ukwazi ubude esibonakalayo esihambisanayo.

3) Ibanga le-Flange

Ukugxila emuva kubhekisela ebangeni elisuka endizeni yokubuka ikhamera ukuya ku-chip. Kuyipharamitha ebaluleke kakhulu futhi inqunywa umkhiqizi wekhamera ngokuya ngomklamo wayo wendlela yokubona. Amakhamera avela kubakhiqizi abahlukene, ngisho anokuxhumana okufanayo, angase abe nokugxila okuhlukile emuva.

4) I-MTF

Ngokukhuliswa kwe-optical, isixhumi esibonakalayo, nokugxila emuva, ibanga lokusebenza nobude beringi ehlangene kungabalwa. Ngemva kokukhetha lezi, kukhona esinye isixhumanisi esibalulekile, esiwukubona ukuthi inani le-MTF lilungile ngokwanele yini? Onjiniyela abaningi ababonakalayo abayiqondi i-MTF, kodwa kumalensi asezingeni eliphezulu, i-MTF kufanele isetshenziselwe ukukala ikhwalithi yokubona.

I-MTF ihlanganisa ingcebo yolwazi olufana nokuqhathanisa, ukulungiswa, imvamisa yendawo, ukushintshashintsha kwe-chromatic, njll., futhi iveza ikhwalithi yokubona yesikhungo kanye nonqenqema lwelensi ngokuningiliziwe. Akukhona nje kuphela ibanga lokusebenza kanye nenkundla yokubuka ehlangabezana nezidingo, kodwa umehluko wamaphethelo awulungile ngokwanele, kodwa nokuthi ukukhetha i-lens yokulungiswa okuphezulu kufanele kucatshangelwe kabusha.
