Itandukaniro riri hagati ya 850nm na 940nm LEDs

Guhiga kameraBabaye igikoresho cyingenzi kubahiga nubusabane bwinyamanswa, ubakwemerera gufata amashusho akomeye na videwo yinyamanswa muburyo bwabo. Kimwe mu bigize bibiri by'ingenzi bya kamera yo guhiga ni iyobowe na infrared (ir), rikoreshwa mu kumurika aho ibintu bitoroshye tutiriwe uhuza inyamaswa. Ku bijyanye no guhiga kamera, ubwoko bubiri bwa Ir Leds ni 850nm na 940nm. Gusobanukirwa itandukaniro riri hagati yubwoko bubiri bwa LED ni ngombwa kugirango uhitemo uburenganziraKamera kubyo ukeneye byihariye.

Itandukaniro ryibanze hagati ya 850nm na 940nm leds iri mumuriro wurumuri rwa infrared se. Uburebure bw'umucyo bupimwa muri Nanometero (NM), hamwe na 850nm na 940Nm bivuga urutonde rwihariye rwibintu byihariye. 800nm ​​isohotse isohora urumuri rugaragara gato kumaso yumuntu, rugaragara nkumukunzi utukura utukura mu mwijima. Ku rundi ruhande, 940nm yatumye urumuri rutagaragara rwose ku jisho ry'abantu, bigatuma ari byiza kugenzurwa no kwitegereza kw'ibinyabuzima.

Muburyo bufatika, guhitamo hagati ya 850nm na 940nm Led biterwa nuburyo bwihariye bwa kamera yo guhiga. Kubahiga bashaka gukurikirana inzira zumukino nibikorwa byinyamanswa bitabangamiye inyamaswa, 940nm iyobowe nibyo guhitamo. Umucyo wacyo utagaragara uremeza ko kamera ikomeje, yemerera imyitwarire mibi kandi yukuri ifatwa kuri kamera. Byongeye kandi, iyobowe na 940nm ntizishobora guterera inyamaswa nijoro, zikabigira uburyo bwiza bwo gufata amashusho hamwe na videwo zo gufata ibiremwa bya nijoro bitoroshye.

Ku rundi ruhande, LETA 800 iyobowe irashobora kuba ikwiye kugenzura rusange n'imikorere myiza. Mugihe isohora urumuri rutukura rudashobora kugaragara kubantu, irashobora kugaragara ninyamaswa zimwe na zimwe zifite icyerekezo cyijoro, nkamoko amwe n'amwe yimpongo. Kubwibyo, niba intego yibanze ari ugukemura ibicumuro cyangwa gukurikirana agace hagamijwe umutekano, 850 LEDM irashobora guhitamo neza kubera urumuri rugaragara.

Ni ngombwa kumenya ko guhitamo hagati ya 850nm na 940nm nanone nabyo bigira ingaruka kumurongo kandi usobanutse neza ya kamera yijoro. Mubisanzwe, leds 850nm itanga urumuri rwiza kandi rurerure ugereranije na 940nm. Ariko, itandukaniro murwego ni mike, kandi ibicuruzwa byo kwiyongera kuri 940nm kugirango habeho inyungu nkeya murwego rwatanzwe na 800nm.

Mu gusoza, itandukaniro riri hagati yimyaka 800 na 940nm Leds mu guhiga kamera zihiga zigenda zigaragara no kutagaragara. Mugihe amafaranga 850 yayoboye urumuri rwose, LETA 940NM itanga itagaragara, ikaba guhitamo kwizirika kwamagare no kugenzura byihishe. Gusobanukirwa ibisabwa byihariye byo guhiga cyangwa kugenzura bizagufasha gufata icyemezo neza mugihe uhisemo hagati yubwoko bubiri bwa LED yawekamera y'ibinyabuzima.
