ʻO ka huina kukuna lens ʻo ia ka huina ma waena o ke axis optical a me ke kukuna aliʻi lens.ʻO ke kukuna nui o ka lens ka kukuna e hele ana ma ka puka puka o ka ʻōnaehana ʻōpika a me ka laina ma waena o ke kikowaena o ka haumāna komo a me ke kiko mea.ʻO ke kumu o ka noho ʻana o CRA i ka Image Sensor aia kahi FOV (Field of view) ma ka Mirco Lens ma ka ʻili o ka Image Sensor, a ʻo ka waiwai o ka CRA e hilinaʻi ʻia ma ka helu kuhi hewa ma waena o ka Micro Lens. o ke Kiʻi Kiʻi a me ke kūlana o ka photodiode silika.ʻO ke kumu e hoʻohālikelike maikaʻi i ka lens.
ʻO ka huina kukui aliʻi lens
Ke koho ʻana i kahi CRA like o Lens&Image Sensor hiki ke hōʻoia i ka hopu pololei ʻana o nā kiʻi i loko o nā kiʻi kiʻi silika, a laila e hōʻemi i ka crosstalk optical.
No nā mea ʻike kiʻi me nā pika liʻiliʻi, ua lilo ke kihi ray nui i mea hoʻohālikelike koʻikoʻi.ʻO kēia no ka mea e hele ka mālamalama i ka hohonu o ka pixel e hiki ai i ka photodiode silicon ma lalo o ka pika, e kōkua i ka hoʻonui ʻana i ka nui o ke kukui e hele pololei i loko o ka photodiode a hoʻemi i ka nui o ke kukui e komo i loko o ke kilika. photodiode o kahi pika pili (Ke hana ʻana i ka crosstalk optical).
No laila, ke koho ka mea ʻike kiʻi i kahi lens, hiki iā ia ke noi i ka mea hana Image Sensor & mea hana lens no kahi pihi CRA no ka hoʻohālikelike ʻana;ʻO ka ʻokoʻa CRA ma waena o ka Image Sensor a me ka lens e hoʻomalu ʻia i loko o +/-3 degere, ʻoiaʻiʻo, ʻoi aku ka liʻiliʻi o ka Pixel, ʻoi aku ka kiʻekiʻe o ke koi.
Nā hopena o ka lens CRA a me ka sensor CRA like ʻole:
ʻO ka like ʻole ka hopena i ka crosstalk e hopena i ke kaulike ʻole o ka waihoʻoluʻu ma ke kiʻi, e hōʻemi ana i ka ratio signal-to-noise (SNR);no ka mea, koi ʻo CCM i ka hoʻonui ʻana i ka waiwai kikohoʻe e uku ai i ka nalowale o ka hōʻailona ma ka photodiode.
Nā hopena o ka lens CRA a me ka sensor CRA mismatch
Inā pili ʻole ka CRA, e hoʻopilikia ʻia e like me nā kiʻi pohihihi, ka noe, ka ʻokoʻa haʻahaʻa, nā kala ʻeleʻele, a me ka hohonu o ke kahua.
ʻOi aku ka liʻiliʻi o ka lens CRA ma mua o ka CRA Sensor kiʻi e hana i ka pale kala.
Inā ʻoi aku ka liʻiliʻi o ke Kiʻi Kiʻi ma mua o ka CRA lens, e hiki mai ana ka uhi ʻana o Lens.
No laila, pono mākou e hōʻoia mua ʻaʻole i ʻike ʻia ke kala kala, no ka mea ʻoi aku ka maʻalahi o ka pale ʻana o Lens ma o ka debugging ma mua o ke kala kala.
ʻIke kiʻi a me ka lens CRA
Hiki ke ʻike ʻia mai ka kiʻi ma luna aʻe ʻo ka TTL o ka lens ke kī i ka hoʻoholo ʻana i ke kihi CRA.ʻO ka haʻahaʻa o ka TTL, ʻoi aku ka nui o ke kihi CRA.No laila, ʻo ka mea ʻike kiʻi me nā pika liʻiliʻi he mea koʻikoʻi loa ia no ka lens CRA hoʻohālikelike i ka wā e hoʻolālā ai i ka ʻōnaehana kamera.
ʻO ka manawa pinepine, ʻaʻole kūlike ka lens CRA i ka CRA sensor kiʻi no nā kumu like ʻole.Ua ʻike ʻia ma ka hoʻokolohua ʻana, ʻoi aku ka ʻae ʻana o nā pihi CRA lens me kahi ʻaoʻao pālahalaha (ka liʻiliʻi liʻiliʻi) i nā ʻano like ʻole o ka hui ʻana o ka pahu pahu pahu ma mua o nā CRA curved.
ʻAʻole kūlike ka lens CRA i ka CRA sensor kiʻi no nā kumu like ʻole
Hōʻike nā kiʻi ma lalo i nā hiʻohiʻona o nā CRA ma luna a me ka curved.
Nā laʻana o nā CRA ma luna a me ka curved
Inā ʻokoʻa loa ka CRA o ka lens mai ka CRA o ka mea ʻike kiʻi, e ʻike ʻia ke kala kala e like me ke kiʻi ma lalo nei.
Hōʻike ʻia ke kala kala
