Yiliphi ilensi elibonisa kangcono indlela abantu abazibona ngayo?
Empilweni yansuku zonke, abantu bavame ukuthembela ezithombeni ukuze babhale phansi ukubukeka kwabo ngokomzimba. Kungakhathaliseki ukuthi ukwabelana ngezinkundla zokuxhumana, izinjongo zokuhlonza ezisemthethweni, noma ukuphathwa kwezithombe zomuntu siqu, ubuqiniso bezithombe ezinjalo sebuyinto ebhekwa kabanzi....Funda kabanzi -
Ilensi yokukhanya emnyama—inikeza ukusebenza okuthuthukisiwe kokubona ebusuku kwezinhlelo zokusebenza zokuqapha ukuphepha
Ubuchwepheshe belensi yokukhanya emnyama bumelela ikhambi lokuthwebula izithombe elithuthukisiwe emkhakheni wokuqapha ukuphepha, elikwazi ukufeza izithombe ezinemibala egcwele ngaphansi kwezimo zokukhanya okuphansi kakhulu (isb., 0.0005 Lux), okubonisa ukusebenza okuhle kakhulu kokubona ebusuku. Isici esiyinhloko...Funda kabanzi -
Umehluko phakathi kwamakhamera e-dome asheshayo namakhamera avamile
Kunomehluko omkhulu phakathi kwamakhamera e-dome asheshayo namakhamera avamile maqondana nokuhlanganiswa kokusebenza, ukwakheka kwesakhiwo, kanye nezimo zokusetshenziswa. Leli phepha linikeza ukuqhathanisa okuhlelekile kanye nokuhlaziywa okuvela ezicini ezintathu ezibalulekile: ubuchwepheshe obuyinhloko...Funda kabanzi -
Ukusetshenziswa kabanzi kobuchwepheshe bokuhlola umbono womshini
Ubuchwepheshe bokuhlola umbono womshini buye bamukelwa kabanzi ezimbonini ezahlukahlukene, okubonisa izinzuzo ezibalulekile ekukhiqizweni kwezimboni, ezempilo, kanye nasekukhiqizweni kwezimoto. Njengobuchwepheshe obuthuthukisiwe obuhlanganisa ukucutshungulwa kwezithombe,...Funda kabanzi -
Uhlobo lwesixhumi esibonakalayo kanye nobude bokugxila kwangemuva kwamalensi optical
Uhlobo lwesixhumi esibonakalayo kanye nobude bokugxila kwangemuva (okungukuthi, ibanga lokugxila kwe-flange) lelensi ye-optical kuyimingcele eyisisekelo elawula ukuhambisana kwesistimu futhi inqume ukufaneleka kokusebenza kokusethwa kwezithombe. Leli phepha liveza ukuhlukaniswa okuhlelekile kwezinhlobo ezivamile...Funda kabanzi -
Umhlahlandlela Wokuhlaziya Ijika Le-MTF
Igrafu yejika le-MTF (Modulation Transfer Function) isebenza njengethuluzi elibalulekile lokuhlaziya lokuhlola ukusebenza kwe-optical kwamalensi. Ngokulinganisa ikhono lelensi lokugcina umehluko kuzo zonke imvamisa yendawo ehlukahlukene, ibonisa ngokubonakalayo izici ezibalulekile zokuthwebula izithombe njengokuphinda...Funda kabanzi -
Ukusetshenziswa kwezihlungi kuwo wonke ama-spectral band ahlukene embonini ye-optical
Ukusetshenziswa kwezihlungi Ukusetshenziswa kwezihlungi kuwo wonke ama-spectral band ahlukene embonini ye-optical kusebenzisa kakhulu amakhono azo okukhetha ubude be-wavelength, okuvumela ukusebenza okuthile ngokushintsha ubude be-wavelength, ubukhali, kanye nezinye izakhiwo ze-optical. Okulandelayo kuchaza...Funda kabanzi -
Yikuphi okufanelekile ukusetshenziswa njengegobolondo lelensi: ipulasitiki noma insimbi?
Ukwakheka kokubukeka kwamalensi kudlala indima ebalulekile kumadivayisi okukhanya anamuhla, lapho ipulasitiki nensimbi kuyizinto ezimbili ezikhethwa kakhulu zezinto ezibonakalayo. Umehluko phakathi kwalezi zinhlobo ezimbili ubonakala kuzo zonke izilinganiso, kufaka phakathi izakhiwo zezinto, ukuqina, isisindo...Funda kabanzi -
Ubude be-Focal kanye ne-field of view yamalensi optical
Ubude be-focal buyipharamitha ebalulekile elinganisa izinga lokuhlangana noma ukuhlukana kwemisebe yokukhanya ezinhlelweni zokukhanya. Le pharamitha idlala indima ebalulekile ekunqumeni ukuthi isithombe sakhiwa kanjani kanye nekhwalithi yaleso sithombe. Lapho imisebe ehambisanayo idlula...Funda kabanzi -
Ukusetshenziswa kwe-SWIR ekuhlolweni kwezimboni
I-Short-Wave Infrared (i-SWIR) yakha ilensi yokukhanya eklanywe ngokukhethekile ukuze ibambe ukukhanya kwe-short-wave infrared okungabonakali ngqo yiso lomuntu. Leli bhande libizwa ngokuthi ukukhanya okunama-wavelength asukela kuma-micron angu-0.9 kuya ku-1.7.Funda kabanzi -
Ukusetshenziswa kwelensi yemoto
Ekhamera yemoto, ilensi ithatha umthwalo wokugxila ukukhanya, iveze into ngaphakathi kwensimu yokubuka ebusweni bendlela yokuthwebula izithombe, ngaleyo ndlela yakhe isithombe esibonakalayo. Ngokuvamile, ama-70% amapharamitha okukhanya ekhamera anqunywa...Funda kabanzi -
