Umucyo karemano ugizwe numuraba wumucyo ufite uburebure butandukanye.Urwego rugaragara mumaso yumuntu ni 390-780nm.Umuhengeri wa electromagnetique uri munsi ya 390nm kandi urenga 780nm ntushobora kumvikana namaso yumuntu.Muri byo, electromagnetic waves ifite uburebure buri munsi ya 390nm iri hanze ya violet yumucyo ugaragara kandi bita imirasire ya ultraviolet;amashanyarazi ya electromagnetic arenga 780nm ari hanze yumutuku wumucyo ugaragara kandi witwa infragre, kandi uburebure bwabyo buri hagati ya 780nm na 1mm.
Infrared ni umuyagankuba wa electromagnetique hamwe nuburebure bwumurongo uri hagati ya microwave numucyo ugaragara, kandi ufite essence imwe numurongo wa radio numucyo ugaragara.Muri kamere, ibintu byose ubushyuhe buri hejuru ya zeru (-273.15 ° C) bikomeza kumurika imirasire yimirasire.Iyi phenomenon yitwa imirasire yumuriro.Ikoreshwa rya tekinoroji ya infrarafarike ikoresha imishwarara ya micrike yumuriro, optique yerekana amashusho hamwe na sisitemu yo gusikana opto-mehaniki kugirango yakire ibimenyetso byerekana imirasire yimirasire yikintu kigomba gupimwa, kandi uburyo bwo gukwirakwiza ingufu za infragre yimirasire yibintu bigaragarira mubintu bifotora byerekana ibintu bitagaragara. nyuma yo kuyungurura ibintu no kuyungurura umwanya, ni ukuvuga, ishusho yubushyuhe bwa infragre yubushyuhe bwikintu cyapimwe irasuzumwa kandi yibanda kuri unit cyangwa disiketi ya spekitroscopique, ingufu zumucyo zidafite imbaraga zihindurwa na detector mukimenyetso cyamashanyarazi, cyongerewe kandi gihinduka amashusho asanzwe ikimenyetso, kandi cyerekanwe nka infragre yubushyuhe bwa ecran kuri TV cyangwa monitor.
Infrared ni umuyagankuba wa electromagnetic hamwe nibintu bimwe na radiyo yumurongo numucyo ugaragara.Ivumburwa rya infragre ni ugusimbuka mubitekerezo byabantu.Tekinoroji ikoresha igikoresho cyihariye cya elegitoronike kugirango ihindure ikwirakwizwa ryubushyuhe hejuru yikintu mu ishusho igaragara ku jisho ryumuntu kandi yerekana ikwirakwizwa ryubushyuhe hejuru yikintu mumabara atandukanye byitwa tekinoroji ya infrarafarike yerekana amashusho.Iki gikoresho cya elegitoronike cyitwa infragre yumuriro.
Imashusho yumuriro wa infragre ikoresha infrared detector, optique yerekana amashusho hamwe na sisitemu yo gusikana opto-mashini (tekinoroji yindege igezweho ikuraho sisitemu yo gusikana opto-mashini) kugirango yakire uburyo bwo gukwirakwiza imirasire yimirasire yikintu kigomba gupimwa no kukigaragariza kuri fotosensitif yibintu bya infragre.Hagati ya sisitemu ya optique na disiketi ya infragre, hariho uburyo bwo gusikana optique-ya mashini (indege yibanze ya firimu ya firime idafite ubu buryo) kugirango isuzume ishusho yubushyuhe bwa infrarafarike yikintu igomba gupimwa no kuyibanda kuri unit cyangwa disiketi ya spekitroscopique. .Imirasire yumucyo ihindurwamo ibimenyetso byamashanyarazi na detector, kandi ishusho yumuriro wa infragre igaragara kuri ecran ya TV cyangwa monitor nyuma yo gukwirakwizwa no guhindurwa mukimenyetso gisanzwe cya videwo.
Ubu bwoko bwamashusho yubushyuhe buhuye nubushyuhe bwo gukwirakwiza ubushyuhe hejuru yikintu;mubyukuri, nigishushanyo mbonera cyo gukwirakwiza amashusho yubushyuhe bwimirasire ya infragre ya buri gice cyikintu kigomba gupimwa.Kuberako ikimenyetso gifite intege nke cyane, ugereranije nigishusho kigaragara cyumucyo, ntikibura amanota nubunini bwa gatatu.Kugirango hamenyekane ikwirakwizwa ryubushyuhe bwa infragre yikintu kigomba gupimwa neza mubikorwa nyirizina, ingamba zimwe zifasha akenshi zikoreshwa mukongera ibikorwa bifatika byigikoresho, nko kugenzura ububengerane bwibishusho no gutandukanya, ibipimo nyabyo gukosora, ibara ryibara rishushanya kontour na histogramu kubikorwa byimibare, gucapa, nibindi.
Kamera yerekana amashusho itanga icyizere mubikorwa byihutirwa
Ugereranije na kamera gakondo zigaragara zishingiye kumucyo karemano cyangwa ibidukikije kugirango ukurikirane kamera, kamera yerekana amashusho ntisaba urumuri urwo arirwo rwose, kandi irashobora kwerekana neza ishusho ishingiye kubushyuhe bwa infragre ikwirakwizwa nikintu ubwacyo.Kamera yerekana amashusho yumuriro ikwiranye nibidukikije byose kandi ntibiterwa numucyo ukomeye.Irashobora kumenya neza no kubona intego, ikanamenya intego zafashwe kandi zihishe utitaye kumanywa cyangwa nijoro.Kubwibyo, irashobora kumenya neza gukurikirana amasaha 24.
