Kusanthula ma lensamagwiritsidwa ntchito kwambiri mu AOI, kuyang'anira kusindikiza, kuyang'anira nsalu zosalukidwa, kuyang'anira zikopa, kuyang'anira njanji, kuyesa ndi kusankha mitundu ndi mafakitale ena. Nkhaniyi ikubweretsa mawu oyamba a magalasi ojambulira mzere.

Chidziwitso cha Ma Lens a Line Scan

1) Lingaliro la mandala ojambulira mzere:

Mzere wa CCD mandala ndi mawonekedwe apamwamba a FA mandala pamakamera amtundu wa sensa mndandanda wolingana ndi kukula kwa chithunzi, kukula kwa pixel, ndipo angagwiritsidwe ntchito pakuwunika kolondola kwambiri.

2) Mawonekedwe a mandala ojambulira mzere:

1. Zapangidwa mwapadera kuti zitheke kusanthula kwapamwamba, mpaka 12K;

2. Pazipita n'zogwirizana chithunzi chandamale chandamale ndi 90mm, ntchito yaitali jambulani kamera kamera;

3. Kusamvana kwakukulu, kukula kochepa kwa pixel mpaka 5um;

4. Mlingo wokhotakhota wotsika;

5. Kukulitsa 0.2x-2.0x.

Zoganizira Posankha Magalasi Ojambulira Mzere

Chifukwa chiyani tiyenera kuganizira kusankha mandala posankha kamera? Makamera ojambulira mzere pano ali ndi malingaliro a 1K, 2K, 4K, 6K, 7K, 8K, ndi 12K, ndi makulidwe a pixel a 5um, 7um, 10um, ndi 14um, kotero kuti kukula kwa chip kumakhala kuyambira 10.240mm (1Kx10um) mpaka 86.016mm (12Kx7um) zimasiyanasiyana.

Mwachiwonekere, mawonekedwe a C ali kutali ndi kukwaniritsa zofunikira, chifukwa mawonekedwe a C amatha kugwirizanitsa tchipisi ndi kukula kwake kwa 22mm, ndiko 1.3 mainchesi. Mawonekedwe a makamera ambiri ndi F, M42X1, M72X0.75, etc. Ma lens osiyanasiyana opangira magalasi amafanana ndi kuyang'ana kumbuyo (Flange mtunda), komwe kumatsimikizira mtunda wogwirira ntchito wa mandala.

1) Kukula kwa kuwala (β, Kukulitsa)

Kapangidwe ka kamera ndi kukula kwa pixel zikatsimikiziridwa, kukula kwa sensa kumatha kuwerengedwa; kukula kwa sensa komwe kugawanika ndi gawo la view(FOV) ndikofanana ndi kukula kwa kuwala. β=CCD/FOV

2) Chiyankhulo (Mount)

Pali makamaka C, M42x1, F, T2, Leica, M72x0.75, etc. Pambuyo potsimikizira, mukhoza kudziwa kutalika kwa mawonekedwe ofanana.

3) Flange Distance

Choyang'ana kumbuyo chimatanthawuza mtunda wochoka pa ndege ya kamera kupita ku chip. Ndi gawo lofunikira kwambiri ndipo limatsimikiziridwa ndi wopanga kamera molingana ndi kapangidwe kake kanjira. Makamera ochokera kwa opanga osiyanasiyana, ngakhale omwe ali ndi mawonekedwe ofanana, amatha kukhala ndi malingaliro osiyanasiyana kumbuyo.

4) MTF

Ndi kukula kwa kuwala, mawonekedwe, ndi kuyang'ana kumbuyo, mtunda wogwirira ntchito ndi kutalika kwa mphete yolumikizana ikhoza kuwerengedwa. Mukasankha izi, palinso ulalo wina wofunikira, womwe ndikuwona ngati mtengo wa MTF ndiwokwanira? Akatswiri ambiri owoneka samvetsetsa MTF, koma magalasi apamwamba, MTF iyenera kugwiritsidwa ntchito kuyeza mawonekedwe a kuwala.

MTF imakhala ndi zidziwitso zambiri monga kusiyanitsa, kusamvana, kuchuluka kwa malo, kusintha kwa chromatic, ndi zina zambiri, ndikuwonetsa mawonekedwe apakati ndi m'mphepete mwa mandala mwatsatanetsatane. Osati mtunda wogwirira ntchito ndi malo owonetserako omwe amakwaniritsa zofunikira, koma kusiyana kwa m'mphepete sikuli kokwanira, komanso ngati kusankha lens yapamwamba iyenera kuganiziridwanso.
