Incazelo yesibuko esiguquguqukayo
Olunye uhlobo lwesibuko olusetshenziswa ekuphileni kwansuku zonke yisibuko esijiyile. Isibuko esijiyile isibuko esigobile, lapho ubuso besibuko obukhombisa ukukhanya bujika phambili.
Sebenzisa
Uma uke wabona isibuko sokubuka emuva sesithuthuthu noma semoto, cishe ujwayelene nokusetshenziswa kwansuku zonke kwezibuko eziqondile. Zisetshenziswa njengezibuko zokubuka emuva ngoba isithombe ezisikhiqizayo sincane, okuvumela insimu ebanzi yokubuka. Ngaphandle kosayizi wesithombe omncane, zonke izithombe ezikhiqizwayo zingokoqobo noma zingokomfanekiso. Sicela ufunde isihloko. isithombe sesibuko esijiyile ukuze kucaciswe ukuqonda kwakho.
Iphuzu Lokugxila
Uma ubuso besibuko obubonisa ukukhanya bubhekene nento ekude kakhulu, njengelanga, khona-ke ukukhanya okuphuma yilanga kuzohambisana ne-axis eyinhloko yesibuko, njengoba kuboniswe esithombeni esingezansi. I-axis eyinhloko ingumugqa ocatshangwayo oqonde phakathi nendawo ebusweni besibuko.
Uma ushaya ubuso besibuko, umsebe ngamunye wokukhanya noma umsebe wokukhanya uyalalela umthetho wokubonakaliswa kokukhanya. Yonke imisebe eboniswayo ibonakala ivela endaweni egxile esibukweni esiqondile (F). Ngamanye amazwi, indawo egxile yindawo yesithombe sento ekude kakhulu nobuso besibuko futhi lesi sithombe singokoqobo.
Ubude be-Focal
Ubude be-focal (f) yibanga eliphakathi kwe-focal point (F) kanye nobuso besibuko. Iphuzu C liyisikhungo sokugoba kwesibuko. Ubude be-focal yesibuko ngu-f (focal length = f = FQ) kanti i-radius yokugoba kwesibuko ngu-r (radius of curvature = r = CQ = CP).
Umsebe wesigameko ushaya isibuko ku-P bese uboniswa yisibuko, lapho umsebe obonakalayo ubonakala uvela endaweni egxile ku-F. Umugqa onamachashazi i-CP ukhona umugqa ojwayelekile. Umsebe wesigameko kanye nomsebe obonisiwe kulalela umthetho wokubonakaliswa kokukhanya lapho i-engeli yokwenzeka (θ) ilingana ne-engeli yokubonakaliswa (θ) futhi le engeli ilingana ne-engeli yonxantathu PCQ (θ). I-engeli yonxantathu PCQ ilingana ne-engeli yonxantathu CPF ngakho-ke unxantathu PFC unxantathu olinganayo. Ngenxa yokuthi unxantathu PFC unxantathu olinganayo khona-ke ubude be-PF bulingana nobude be-CF. Ngokuthatha ukuthi ububanzi besibuko buncane kune-radius yokuguquka kwesibuko esijijekile ngakho-ke ubude be-PF bubhekwa njengobulingana nobude be-FQ. Ngenxa yokuthi i-CF = PF kanye ne-PF = FQ khona-ke i-CQ = 2 CF = 2 FQ. I-CQ = r = i-radius yokuguquka kwesibuko kanye ne-FQ = f = ubude bokugxila kwesibuko. Ngakho-ke kungaphethwa ngokuthi i-radius yokuguquka kwesibuko (r) = 2 x ubude bokugxila (f) besibuko. Ngokwezibalo:
r = 2 f noma f = r / 2
Isithunzi
Izibuko ezigobile zingakha izithombe zangempela nezingokoqobo, kanti izibuko ezigobile zingakha izithombe ezibonakalayo kuphela. Ukwakheka kwesithombe sento ngesibuko esigobile kuchazwe ngokuningiliziwe esihlokweni isithombe sesibuko esijiyile.
Isithunzi sikaMaya
Uma ukukhanya okuza ebusweni besibuko kuboniswa, isiqondiso sokukhanya okubonakalayo sibonakala sivela endaweni egxile esibukweni kanye nasenkabeni yokugoba kwesibuko. Ngenxa yokuthi ukukhanya akudluli ngemuva kwesibuko, isithombe esakhiwe sibonakala isithunzi esibonakalayo noma iphantomUma ubeka isikrini endaweni lapho isithombe esibonakalayo sitholakala khona, akukho sithunzi esizovela esikrinini.
