Ke hilinaʻi nui nei nā mīkini nānā X-ray i kā lākou ʻenehana ʻike i kūkulu ʻia a me nā algorithms i ka wā e hoʻokaʻawale ai ma waena o nā metala a me nā mea ʻē aʻe. No ka laʻana, metala detectors (me ka meaʻai metala detectors, plastic metala detectors, hoomakaukau meaʻai metala detectors, hoomakaukau meaʻai metala detectors, etc.) nui hoʻohana i ka loina o electromagnetic induction e ike metala haole mea. Ke komo ka mea metala i ka ʻāpana ʻike o ka mea ʻike metala, hoʻopau ia i ke kahua magnetic equilibrium i hoʻokumu ʻia e ka transmitter a me ka mea hoʻokipa, e hana ana i kahi hoʻololi hōʻailona ma ka mea hoʻokipa e hoʻāla ai i kahi puʻupuʻu a hōʻike i ke alo o kahi mea hao hao.

Eia nō naʻe, no nā mea ʻē aʻe ʻaʻole metala e like me nā pōhaku, aniani, iwi, plastics, etc., ʻaʻole hiki i nā mea ʻike metala ke ʻike pololei iā lākou. I kēia hihia, pono nā ʻano mīkini ʻike kino ʻē aʻe, e like me nā mīkini nānā X-ray (i ʻike ʻia ʻo X-ray foreign body inspection machines a i ʻole X-ray foreign body inspection machines) pono e hana i ka nānā.

X-ray inspection machine hoʻohana i ka hiki ke komo o X-rays e hoʻomaopopo a hoʻokaʻawale i ka metala a me ka non-metallic haole kino i loko o ka mea ma ke ana ana i ka degere o ka attenuation o X-kukui ma hope o ke komo 'ana i ka mea i nānā 'ia, a me ka hui 'ana i ka 'ike loea kiʻi. Hiki i nā kukui X ke komo i ka hapa nui o nā mea metala ʻole, akā hiki ke attenuation ikaika i ka wā e hālāwai ai me nā mea kiʻekiʻe e like me nā metala, no laila e hana i kahi ʻokoʻa maopopo i ke kiʻi a hiki i ka ʻike pololei ʻana o nā kino haole metala.

ʻO ka hopena, ʻokoʻa ka ʻokoʻa ma waena o ka metala a me nā mea ʻē i nā mea ʻike kino haole ma muli o ka ʻenehana ʻike a me ka algorithm i hoʻohana ʻia. Hoʻohana mua ʻia nā mea ʻike metala no ka ʻike ʻana i nā mea ʻē aʻe, ʻoiai nā x-ray detectors e hiki ke ʻike i kahi ākea o nā mea ʻē aʻe, me ka metala a me ka non-metallic, ʻoi aku ka laulā.

Eia kekahi, i ka hoʻomau ʻana o ka ʻenehana, hiki i kekahi mau mea ʻike kino ʻē aʻe ke hoʻohana i ka hui pū ʻana o nā ʻenehana ʻike he nui no ka loaʻa ʻana o ka ʻike ʻoi aku ka pololei a me ka piha o nā ʻano o nā kino haole. No ka laʻana, hiki i kekahi mau mea hana ke hoʻohui i ka ʻike metala a me ka hiki ke ʻike maka X-ray e hoʻomaikaʻi i ka pololei a me ka hilinaʻi o nā nānā.
