22/02/25ʻO ka Quantum Efficiency (QE) o kahi mea ʻike e pili ana i ka hiki ke paʻi ʻia nā kiʻi kiʻi i ka mea ʻike i ʻike ʻia ma %. Ke alakaʻi nei ʻo QE kiʻekiʻe i kahi kāmela maʻalahi, hiki ke hana i nā kūlana māmā haʻahaʻa. Pili pū ka QE i ka nalu nalu, me ka QE i hōʻike ʻia ma ke ʻano he helu hoʻokahi e pili ana i ka waiwai kiʻekiʻe.
Ke hahau nā kiʻi paʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi. Eia naʻe, e hoʻopili ʻia kekahi mau kiʻi paʻi kiʻi, ʻike ʻia, a hoʻopuehu ʻia paha e nā mea o ka ʻike pahupaʻi ma mua o ka hiki ke ʻike ʻia. ʻO ka pilina ma waena o nā kiʻi a me nā mea o ka mea ʻike kiʻi kiʻi e pili ana i ka lōʻihi o ka nalu photon, no laila ke hilinaʻi ʻia ka loaʻa ʻana o ka nalu. Hōʻike ʻia kēia hilinaʻi ma ka Quantum Efficiency Curve o ke kāmela.
Ka laʻana o ka pākuʻi Quantum Efficiency. ʻulaʻula: CMOS i hoʻomālamalama ʻia ma hope. Polū: ʻO CMOS hoʻomālamalama mua ʻaoʻao kiʻekiʻe
Hiki ke loaʻa nā QE ʻokoʻa i nā mea ʻike kamera like ʻole ma muli o kā lākou hoʻolālā a me nā mea. ʻO ka mana nui loa ma QE inā paha i hoʻomālamalama ʻia ka sensor o kahi kāmela a i ʻole ka ʻaoʻao mua. Ma nā kāmeʻa hoʻomālamalama ʻaoʻao mua, pono e hele mua nā kiʻi kiʻi mai ke kumuhana i kahi pā o ka uea ma mua o ka ʻike ʻia. ʻO ka mea mua, ua kaupalena ʻia kēia mau kāmela i ka quantum efficiencies ma kahi o 30-40%. ʻO ka hoʻokomo ʻana o nā microlenses e nānā i ka mālamalama ma mua o nā uea i loko o ka silikona māmā māmā i hoʻonui ʻia i kēia ma kahi o 70%. Hiki i nā kāmela i hoʻomālamalama mua ʻia ke hiki i nā QE kiʻekiʻe ma kahi o 84%. Hoʻohuli nā kiʻi paʻi kiʻi hope i kēia hoʻolālā sensor, me nā kiʻi kiʻi e paʻi pololei ana i kahi ʻāpana ʻike kukui ʻoniʻoni o ke silicon, me ka hele ʻole ʻana i nā uwea. Hāʻawi kēia mau mea ʻike kiʻi kiʻi kiʻekiʻe ma kahi o 95% kiʻekiʻe, ma ke kumukūʻai o kahi kaʻina hana ʻoi aku ka ikaika a me ka pipiʻi.
ʻAʻole lilo ka Quantum Efficiency i mea koʻikoʻi i kāu noi kiʻi. No nā noi me nā pae kukui kiʻekiʻe, hoʻonui ka QE a me ka naʻau i hāʻawi iki i ka pōmaikaʻi. Eia nō naʻe, ma ke kiʻi māmā haʻahaʻa, hiki i ka QE kiʻekiʻe ke hoʻonui i ka ratio signal-to-noise-ratio a me ka maikaʻi o ke kiʻi, a i ʻole ka hōʻemi ʻana i nā manawa hōʻike no ke kiʻi wikiwiki. Akā, pono e kaupaona ʻia nā pono o ka pono quantum kiʻekiʻe i ka piʻi ʻana o 30-40% o ke kumukūʻai o nā mea ʻike hoʻomālamalama i hope.
