Ka ʻike e pili ana i nā ʻāpana lens (hiki ke hoʻokaʻawale ʻia kēia ʻatikala i hoʻokahi a ʻelua paha e like me ka ʻike)

1. Nui kiʻi

ʻO ka nui kiʻi ka nui o ka pale;

Nui kiʻi o ka mea ʻike:

E hoʻomau i ka hoʻohana ʻana i ka nui format maʻamau o ka pahu pahupaʻikiʻi, ʻo ia ka nui o waho o ka pahu pahu pahu pahu.

2.Focal lōʻihi

ʻO ka manaʻo e pili ana i ka mamao mai ke kikowaena o ka lens a hiki i ke kiko o ka hōʻiliʻili māmā. ʻO ia hoʻi ka mamao mai ke kikowaena o ka lens a i ka mokulele kiʻi o ka ʻili sensor i loko o ka module. ʻikepili, a e hoʻohana ʻia ia i ka helu ʻana i ka hohonu o ke kahua a me FOV i ka wā e hiki mai ana.

3.Kuanaike

ʻEkolu ʻano o nā lens: lens standard, wide-angle, and telephoto lens.

ʻOiai ʻo ka wahi i ʻike ʻia e ka maka kanaka hiki ke hiki i nā degere 180, ʻo ke kihi hiki ke ʻike maoli i ke ʻano a me ke kala ma kahi o 50 degere.ʻOiaʻiʻo, pono e hoʻokumu ʻia i nā pono maoli o nā mea kūʻai aku; ʻO ke kumu ʻo Seesaw, manaʻo nā mea hana Lens e hoʻolālā i kahi kahua ʻoi aku ka nui o ka nānā ʻana i hiki ke kūpono i nā mea ʻike he nui, akā ʻoi aku ka nui o ka ʻike, ʻoi aku ka nui o ka chromatic aberration e pono ai. e lanakilaia.

4.Chromatic aberration

ʻAʻole hiki i ka lens kiʻi ke hoʻihoʻi loa i kahi kiko a i ʻole ke kiʻi māmā i hui pū ʻia me ka lōʻihi hawewe i kahi kiko, akā he wahi puʻupuʻu puʻupuʻu;ʻO ke kiʻi o ka mea mokulele ʻaʻole ia he mokulele, akā he ʻili ʻāwili, a ua nalowale ke kiʻi i ka like.Ua kapa ʻia kēia mau hemahema kiʻi he chromatic aberrations.

5.Depth of Field & Depth of Focus

(1) Hohonu o ke kahua a me ka Hohonu o ka Mana'o
Ma mua a ma hope o ka nānā ʻana, hoʻomaka ka mālamalama e hōʻiliʻili a hoʻopuehu, a lilo ke kiʻi o ke kiko i polū, e hana ana i kahi pōʻai nui.Kapa ʻia kēia pōʻai ʻo ka pōʻai huikau.

ʻO ka ʻoiaʻiʻo, ʻike ʻia ke kiʻi i hopu ʻia ma kekahi ʻano (e like me ka projection, magnification i ke kiʻi, etc.).ʻO ke kiʻi i manaʻoʻia e ka maka'ōlohelohe, he pilina nui me ka hoʻonui, ka mamao o ka projection a me ka mamao nānā.Inā ʻoi aku ka liʻiliʻi o ke anawaena o ka pōʻai huikau ma mua o ka mana hoʻokae o ka maka kanaka, ʻaʻole hiki ke ʻike ʻia ka blur i hana ʻia e ke kiʻi maoli i ka pae pili.Ua kapa ʻia kēia pōʻai huikau hiki ʻole ke ʻae ʻia.

(2) hohonu o ke kahua
Aia ka pōʻai huikau i ʻae ʻia ma mua a ma hope o ke kiko kiko, a ʻo ka mamao ma waena o nā pōʻai huikau ʻelua i kapa ʻia ʻo ka hohonu o ka nānā ʻana.Ma mua a ma hope o ke kumuhana (kahi kiko), aia nō ka laulā o ke kiʻi, ʻo ia ka hohonu o ke kahua.ʻO ia hoʻi, ʻo ka hohonu o mua a hope o ke kumuhana a me ke kiʻekiʻe o ke kiʻi blur ma ka ʻili o ke kiʻiʻoniʻoni aia i loko o ka palena o ka pōʻai i ʻae ʻia o ka huikau.
'Oko'a ka hohonu o ke kula me ka lō'ihi o ka lens, ka waiwai aperture, a me ka mamao pana.No ka lōʻihi paʻa a me ka mamao pana, ʻoi aku ka liʻiliʻi o ka aperture i hoʻohana ʻia, ʻoi aku ka hohonu o ke kahua.Ke kumu o ka myopic aloha squinting.

(3) Laʻana
Nānā hihia,CNF7246, Lens DS628A
Ka palena, EFL=2.94mm FNO=2.0 SENSOR PIXEL SIZE=1.75um

(4)Vcm kekahi mau hiʻohiʻona maikaʻi ʻole
Ka nānā pono ʻole
I ka hoʻolālā ʻana i ka mea paʻa, ʻo ke kāʻei hope o ka lens mai kahi mamao a kokoke i loko o ka laulā o ka VCM.Inā ʻaʻole i hoʻolālā maikaʻi ʻia ke kiʻekiʻe o ka Mea Paʻa, e ʻike ʻia kahi mea paʻa i ka lens kokoke i ka nānā ʻana, e hopena i ka ʻino kokoke i ka nānā ʻana.

6. Distortion

ʻO ka mea i kapa ʻia ʻo distortion e pili ana i ke kiʻekiʻe o ka huli ʻana o kahi laina pololei i ka pihi ma hope o ka pana ʻana ma ka lens.Ua helu ʻia ke degere o ka distortion e like me ka pakeneka o ka hoʻololi ʻana i ka nui kiʻi i ka nui kiʻi maikaʻi. pili i ka pololei a me ka curvature o ka laina.No laila, hopohopo nui ka nui o nā lens imaging e pili ana i ka deviation o ke kihi ākea o ka hoʻonui, hoʻonohonoho maʻamau i 2%.

7. Ka malamalama pili

ʻO ka manaʻo, ka lākiō hoʻomālamalama o ke kahua o ka nānā ʻana ma ka axis optical a i ka piha piha o ka ʻike ma ka mokulele imaging, ʻo ia hoʻi, ka ratio o nā kihi diagonal o ka mea ʻike kiʻi i ka mālamalama waena, ua kaupalena ʻia kēia waiwai e ka cos4θ theorem of illuminance, and the corners are unit area He haʻahaʻa ka holo ʻana o ka ʻālohilohi, akā ʻaʻole haʻahaʻa loa i loaʻa kahi hanana o ka vignetting.
