Kamera na near-infrared: Ni chi? An yi amfani da shi?

Imejin NIR ya ci gaba technologi na wani aiki da ke karamin fahimta daga rubutuwa 650nm tare da 950nm. Kuna same sauran imaging na rayuwarsa, NIR ya kawo shirya abubuwan rubutuwar rangin, ya kanan zabiyyar wannanƙasa daidai. Wannan fadiffada ya yi NIR imaging technologi sabon labari da ke samun hanyar manyan cikakken, tare da idanin hadinai da idanin kwaliyarin industrial.

An yi ba haɗi NIR imaging technology?

Technologi na imagjin NIR ya yi amfani da wannan kewaye da ke samun hanyar imagjin na optikan. Ya amfani da spetar na electromagnetic, specifically rubutuwar babban da ke so da rubutuwar rayuwarsa, daga 650nm tare da 950nm. Ya kamata tsaye complex objects, ya biyu images detailed daga cikakken wani halitta.

Imejin NIR yanayi a cikin tsarin rubutuwa da kuma suna, ya yi amfani da tabbata na wani sabon gaba daga wannan suna da ke samun hanyar dukkura mai shirya. Kamar yadda ta karatu zuwa hanyar imagijin kula, imagijin NIR bai da farfin rana bai, yayi aiki da imagijin dai dai, ya kan zama ake samun fahimta don mutum aiki.

Wannan ne yanzu na farko na amfani da NIR imaging, amfani da aka yi aiki da aka samun samar daidai a cikin abubuwan mataki, misali plastics da tace na jinsa. A kanan nan, systemar da aka yi amfani da imagijin NIR ya kamata aiki daidai a cikin wannan hanyar rubutuwa da kuma amfani da rubutuwa dai dai da idaka mai sauran rubutuwa.

Kana, imagijin NIR ya gabatar da wani tambaya. Misali, abubuwan da matsalolin ruwa su ga 700nm to 1000nm bai sami wannan bai a modula kamara NIR . Kuma, domin lack of ambient light, imagijin NIR bai aika bai a cikin wannan hanyar rubutuwa da aka samun amfani da tambayoyin rubutuwa tambayoyi.

An yi imagijin NIR wannan?

Daga cikin shirya imaging NIR, ya kawo taimakon da fatan nan a cika duniya ta teknoloji na sensor suka yi wa yanzu da wadda da hanyar electromagnetic spectrum. Imaging NIR ya kawo daga cikin kamara mai amfani da sabbin wadannan a kan kula da near-infrared range a kan cikin visible spectrum. An kawo wavelengths a matsayi da visible red light, ya za'a 700nm, up to 950nm.

Kamara NIR, misali domin yana amfani da night vision ko traffic monitoring, suka sami sensors mai amfani da sabbin wadannan a kan near-infrared spectrum. Traditionally, CCD sensors ya kawo daga cikin imaging NIR, amma da fatan nan CMOS technology ya kawo rubutu da field. Sensors CMOS suka ne mai amfani da sabbin wadannan a kan near-infrared range, domin gaskiya 850nm, kuma ya kawo su ke nufin wannan da cost-effective da kuma mai amfani da sabbin wadannan a kan applications.

Don gano shafi NIR, kamera yana daidaita ga rubutun base ta daga cikin wannan ake suna mai tunani daidai don sabon rayuwar NIR kuma ya kamata daidai don rayuwar samar da ke so. Kuna iya hanyar suka shekararwa:

• Fasalin rayuwar: Kamara NIR yana daidaita ga lensai ke amfani daidai don fokusar rayuwar NIR daga cikin sensorin kamera.
• Rubutun sensorin: Sensorin kamera ya rubuta rayuwar da aka fasalin zuwa alamun elektriki.
• Sanyin hanyar: Alamun elektriki naɗan yi hakuri don tsarin wakaƙa digital don sha fara amfani daɗe amfani daɗe.

Babban da, kwalite ne NIR imaging yana gabatar daidai don hanyar mai tunani. Mataki, image intensifiers yana saukar daidai don kamera ya fasalin wakaƙa mai amfani daɗe daga cikin samar daidai. Kamar shi, amfani da filters yana saukar daidai don bincika rayuwarsu mai samar, don kamera ya kasance rayuwar NIR mai amfani daɗe don wannan amfani.

Tatsuniya daidaiwa don shirin NIR

An kira daga bayan ciki na amfani, makarantar shirin NIR an bache da fatan. Kwayoyin makaranta ya gabata da nufin $285 million dollar yanzu 2019, ya kamata aikin $485 million dollar don 2030. Wannan rubutu an samfara da wannan nan daidaiwa da NIR teknoloji a cikin gwamnati, hanyoyi, zangonƙasa, suka da iyalcin gaba.

Ana so da ke? Kamarin kamera NIR?

Kamara NIR yana idafa a cikin rubutu da wadannan daga rakin-infa'ar gaba, kuma yanzu daga 700nm tare da 1000nm. An yi haka talla'a daya masu sensor mai tsarin da ke tabbatar da tsari na rayuwar infa'ar kamar tsari na rayuwarsu. Tsarin bayan quantum (QE) na wannan sensors suna iya baya mai amfani da suka samu photons a cikin shirin da suka zama electrons, dai dai suka yi amfani da su a cikin alamunna images. Bayan quantum yana iya rubutu mai amfani da kamara NIR. An yi haka aiki na kamara a cikin samun photons a cikin shirin da suka zama signals elektrika mai samu. QE mai tabbatarsu ya faruwa image mai kyau, kuma a cikin shirin rayuwar gabatar.

Kuna fi nuna rayuwar NIR a cikin sensor kamara, an yi amfani da sabon hakuri a cikin rubutu alamunna. Hakuri na sabon haɗin yana iya yi amfani da sabon hakuri a cikin rubutu alamunna. Hakuri na sabon haɗin yana iya yi amfani da sabon hakuri a cikin rubutu alamunna. Algoritmas da aka yi amfani da sabon hakuri a cikin rubutu alamunna yana iya yi amfani da sabon hakuri a cikin rubutu alamunna.

Kamara ta NIR yana iya aikatawa filta kula don holliwa cikin kwani na wadannan hanyar. Matakan daidai, filta ta RGB yana iya aikatawa don samfara rubutuwa da holliwa cikin kullum kula. Lakin, daga cikin NIR tambaya, hanyar filtar sauran suna zai iya taimaka ko shigar da filtar ta infrared-pass don bayyana rayuwar infrared na guda zuwa sensa, ya ke takadduna wannan hanyar.

Holliwa cikin kontrolin exposure yana iya amfani da wannan anfani daidai don samun hanyar na NIR mai wasuwa. Exposure na gabatarwa zai sanya masu gabatarwa waɗanda, kamar underexposure zai sanya masu gabatarwa daidai ko hanyar tsallakon. Kamara ta NIR binciken yana iya automatic exposure don samun wataƙen exposure da aperture don samun hanyar mai wasuwa daga cikin shirin tunani. Babban da, samun aspect ratio na karfi yana iya samun gabatarwa daidai, yayi abin da ya kamata daidai don samun analisis da interpretation.

Kunan fayilci daidai a cikin rubutu RAW yana biyu amfani ya kawo hanyar wata daidai na ciki a matsayi, kuma an yi daga cikin wannan suna mai duba daidai. Wannan ne kamar shi a cikin samun bayanin NIR, nar zamu dauko masu riga daidai ta fitar da sabon rayuwa. An yi amfani da sabon filtar IR mai kwalite daidai, an saukar da kwayoyin fayilci a cikin gaba daidai a kula rayuwanci.

Sabon hanyar da amfani da NIR cameras
