Isingeniso Sekhamera Ye-Spectrum Egcwele: Izinzuzo Namakhono
Amakhamera e-spectrum agcwele aguqule umkhakha wokuthatha izithombe ngokunikeza ukuguquguquka okungenakuqhathaniswa nokuguquguquka. Ngokungafani namakhamera endabuko anomkhawulo ekuthwebuleni ukukhanya okubonakalayo, amakhamera e-spectrum agcwele angathwebula ububanzi obubanzi be-electromagnetic spectrum, okuhlanganisa ukukhanya kwe-ultraviolet (UV) kanye ne-infrared (IR). Leli khono elinwetshiwe libenza babaluleke kakhulu ezinhlelweni ezihlukahlukene, kusukela ekucwaningweni kwezinkanyezi nophenyo lwe-forensic kuya ocwaningweni lwemivubukulo kanye nokuthatha izithombe kwansuku zonke.
Ukuqonda I-Spectrum Yokukhanya: Okubonakalayo, I-infrared, ne-Ultraviolet
● I-Electromagnetic Spectrum
I-spectrum ye-electromagnetic ihlanganisa zonke izinhlobo zemisebe kagesi, kusukela kumaza omsakazo kuya emisebeni ye-gamma. Ukukhanya okubonakalayo, ukukhanya okungabonwa iso lomuntu, kuyingxenye encane yalo mkhakha. Ukukhanya kwe-infrared (IR) kanye ne-ultraviolet (UV) akubonakali ngeso lenyama kodwa kungathathwa amakhamera agcwele i-spectrum.
● Umehluko Phakathi Kokukhanya Okubonakalayo, Kwe-Infrared, kanye Ne-Ultraviolet
Ukukhanya okubonakalayo kuhluka kusuka cishe ku-400 kuya ku-700 nanometers nge-wavelength. Ukukhanya kwe-infrared kungaphezu nje kwe-spectrum ebonakalayo, kusukela kuma-nanometer angaba ngu-700 kuya ku-1 millimeter. Ngakolunye uhlangothi, ukukhanya kwe-ultraviolet kunobude obufushane bamaza, obusukela kuma-nanometer angaba ngu-10 kuye kwangu-400. Amakhamera e-spectrum egcwele aklanyelwe ukuthwebula zonke lezi zinhlobo zokukhanya, azenze zisebenziseke ngezindlela eziningi ngendlela emangalisayo.
Ukuguqulwa Kwangaphakathi: Inqubo Yokuguqulwa
● Ukukhipha Isihlungi Sokuvimba i-IR
Isihluthulelo sokuguqula ikhamera evamile ibe ikhamera ye-spectrum egcwele ukususwa kwesihlungi sangaphakathi sokuvimbela i-IR, esaziwa nangokuthi isihlungi se-low-pass noma i-hot-mirror. Lesi sihlungi siklanyelwe ukuvimba ukukhanya kwe-IR futhi sivumele ukukhanya okubonakalayo kuphela ukuthi kufinyelele inzwa yekhamera. Ngokuyisusa, ikhamera iyakwazi ukuthwebula ukukhanya kwe-IR ne-UV ngaphezu kokukhanya okubonakalayo.
● Ukufaka Isihlungi Esicacile
Uma isihlungi sokuvimbela i-IR sesisusiwe, isihlungi esicacile sifakwa endaweni yaso. Lesi sihlungi esicacile sivumela ikhamera ukuthi ithwebule yonke i-spectrum yokukhanya. Njengoba isihlungi esicacile sisendaweni, inzwa yekhamera manje ingakwazi ukubona ukukhanya kwe-UV, okubonakalayo, kanye ne-IR, okuyenza ikhamera ye-spectrum yangempela yangempela.
