Amalensi okuskenazisetshenziswa kabanzi ku-AOI, ukuhlolwa kokuphrinta, ukuhlolwa kwendwangu engalukiwe, ukuhlolwa kwesikhumba, ukuhlolwa komzila wesitimela, ukuhlolwa kokuhlunga nombala kanye neminye imboni. Lesi sihloko siletha isingeniso kumalensi okuskena umugqa.

Isingeniso Selensi Yokuskena Umugqa

1) Umqondo ngelensi yokuskena umugqa:

Ilensi ye-CCD yomugqa we-line array iyilensi ye-FA esebenza kahle kakhulu yamakhamera ochungechunge lwezinzwa zomugqa ahambisana nosayizi wesithombe, usayizi wamaphikseli, futhi ingasetshenziswa ekuhlolweni okuhlukahlukene okunembe kakhulu.

2) Izici zelensi yokuskena umugqa:

1. Yakhelwe ngokukhethekile izinhlelo zokusebenza zokuskena ezinesinqumo esiphezulu, kufika ku-12K;

2. Indawo efanelekile yokuthwebula izithombe ingu-90mm, kusetshenziswa ikhamera yokuskena ende;

3. Isixazululo esiphezulu, usayizi wephikseli omncane ofika ku-5um;

4. Izinga eliphansi lokuphambuka;

5. Ukukhulisa 0.2x-2.0x.

Izinto Okufanele Uzicabangele Ngokukhetha Ilensi Yokuskena Umugqa

Kungani kufanele sicabangele ukukhethwa kwelensi lapho sikhetha ikhamera? Amakhamera ajwayelekile okuskena imigqa njengamanje anezinqumo ze-1K, 2K, 4K, 6K, 7K, 8K, kanye ne-12K, kanye nosayizi wamaphikseli we-5um, 7um, 10um, kanye ne-14um, ukuze usayizi we-chip usuke ku-10.240mm (1Kx10um) uye ku-86.016mm (12Kx7um) uhluke.

Ngokusobala, isikhombikubona se-C asihlangabezani nezidingo, ngoba isikhombikubona se-C singaxhuma kuphela ama-chip anosayizi omkhulu ongu-22mm, okungu-1.3 amayintshi. Isikhombikubona samakhamera amaningi yi-F, M42X1, M72X0.75, njll. Izikhombikubona ezahlukene zelensi zihambisana nokugxila okuhlukile emuva (ibanga le-Flange), okunquma ibanga lokusebenza ngelensi.

1) Ukukhulisa okubonakalayo (β, Ukukhulisa)

Uma isinqumo sekhamera kanye nosayizi wephikseli sekunqunyiwe, usayizi wesenzwa ungabalwa; usayizi wesenzwa ohlukaniswe ngensimu yokubuka (i-FOV) ulingana nokukhulisa okubonakalayo. β=CCD/FOV

2) Isikhombimsebenzisi (Faka)

Kukhona ikakhulukazi i-C, i-M42x1, i-F, i-T2, i-Leica, i-M72x0.75, njll. Ngemva kokuqinisekisa, ungazi ubude besixhumi esibonakalayo esifanele.

3) Ibanga le-Flange

Ukugxila emuva kubhekisela ebangeni elisuka endaweni yokuxhumana kwekhamera kuya ku-chip. Kuyipharamitha ebaluleke kakhulu futhi kunqunywa umenzi wekhamera ngokuya ngomklamo wayo wendlela yokukhanya. Amakhamera avela kubakhiqizi abahlukene, ngisho noma ene-interface efanayo, angaba nokugxila emuva okuhlukile.

4) I-MTF

Ngokukhulisa okubonakalayo, isikhombikubona, kanye nokugxila emuva, ibanga lokusebenza kanye nobude bendandatho ehlangene kungabalwa. Ngemva kokukhetha lokhu, kukhona esinye isixhumanisi esibalulekile, esiwukubona ukuthi inani le-MTF lilungile ngokwanele? Onjiniyela abaningi ababonayo abaqondi i-MTF, kodwa kumalensi aphezulu, i-MTF kumele isetshenziswe ukukala ikhwalithi yokubona.

I-MTF ihlanganisa ulwazi oluningi olufana nokuqhathanisa, isixazululo, imvamisa yendawo, ukuphambuka kwe-chromatic, njll., futhi iveza ikhwalithi yokukhanya yesikhungo kanye nomphetho welensi ngemininingwane eminingi. Akukhona nje kuphela ukuthi ibanga lokusebenza kanye nensimu yokubuka kuyahlangabezana nezidingo, kodwa futhi ukuphambana kwemiphetho akwanele, kodwa futhi nokuthi ukukhetha ilensi enesisombululo esiphezulu kufanele kucatshangelwe kabusha.
