Kwadalwa ngo 2025.12.19
Uma uke wacabanga ukuthi ikhamera yakho ye-USB ejwayelekile ingakwazi “ukubona” ngaphezu komkhakha wokukhanya okubonakalayo, awuwedwa. Kusukela kumaphrojekthi wokubona ebusuku kuya ekuhloleni kwezimboni, ukutholwa kwe-infrared (IR) sekuphenduke ikhono elifunwa kakhulu ngabasebenzisi bekhamera ye-USB. Impendulo emfushane? Yebo, kodwa kunezixwayiso ezibalulekile. Ngokwehlukile ku-IR amakhamera, amamojula e-USB kamakhamera amaningi adinga ukulungiswa noma imishini ethile ukuze akwazi ukuthola ukukhanya kwe-infrared ngokwethembeka. Kule mhlahlandlela ephelele, sizochaza ukuthi amakhamera e-USB axhumana kanjani ne-IR radiation, sihlole izindlela zokulungisa ezizenzekelayo, futhi sikhombise izixazululo zobungcweti ezishintsha imikhakha ngo-2025.
Isayensi Ngemuva Kwamakhamera e-USB Ne-Infrared
Ukuze siqonde ukutholwa kwe-IR, okokuqala kufanele sihlukanise ukuthi ama-module we-USB camera asebenza kanjani. Ekuqaleni kwawo, lezi zisetshenziswa zisebenzisa noma ama-sensors e-CMOS (Complementary Metal-Oxide-Semiconductor) noma i-CCD (Charge-Coupled Device) ukuze ziguqule ukukhanya kube izimpawu zikagesi. Ukukhanya okubalulekile? Zombili izinhlobo zama-sensors zihlala zikhombisa ubuhlakani bokukhanya kwe-infrared—kodwa abakhiqizi bahl intentionally block le msebenzi ukuze isetshenziswe nsuku zonke.
Kungani kuvinjelwe i-IR? Ukukhanya okubonakalayo kanye ne-infrared radiation kuhlangana emkhakheni we-electromagnetic (400–700nm yokubona, 700nm–1mm ye-IR). Ngaphandle kokungenelela, ukukhanya kwe-IR kuzophambanisa ukunemba kwemibala ezithombeni nasevidiyweni, kudale imibala engalungile. Ukuze kulungiswe lokhu, amakhamera e-USB afaka ifilitha ye-IR cut (eyaziwa nangokuthi ifilitha yokuvimbela i-IR)—ingxenye encane yengilazi enombala obomvu/ophephuli emnyama ethatha ama-wavelengths e-infrared ngenkathi idlulisa ukukhanya okubonakalayo.
Lo mfilitha uyisithiyo esiyinhloko ekutholeni i-IR. Ukususa lokhu, ikhamera ye-USB ejwayelekile ingabamba ukukhanya kwe-near-infrared (NIR) (700–1400nm). Nokho, ukuze kutholwe ukukhanya kwe-mid- to far-infrared (1400nm–1mm), kudingeka ama-sensors akhethekile afana ne-InGaAs (Indium Gallium Arsenide), njengoba ama-sensors e-CMOS/CCD ehluleka ukugcina ubuchwepheshe bawo ngaphezu kwe-1100nm.
