Incazelo yesibuko esijiyile
Olunye uhlobo lwesibuko olusetshenziswa ekuphileni kwansuku zonke yisibuko esijiyile. Isibuko esijiyile sinezimo ezigobile, lapho ubuso besibuko, obubonisa ukukhanya, bugobela phambili.
Ukusetshenziswa kwesibuko esijiyile
Uma uke wabona isibuko sokubuka emuva sesithuthuthu noma semoto, vele, usuvele uyazi ukusetshenziswa kwezibuko ezigobile empilweni yansuku zonke. Izibuko zisetshenziswa njengezibuko zokubuka emuva ngoba izithombe ezakhiwe ngezibuko ezigobile ziqondile, futhi izithombe zincane kunezinto ukuze zibe nobubanzi bokubukwa. Ngaphezu kosayizi wesithombe omncane, zonke izithombe ezakhiwe ngezibuko ezigobile zingokoqobo.
Indawo ebalulekile yesibuko esijiyile
Uma ubuso besibuko obubonisa ukukhanya buvezwa entweni ekude kakhulu njengemisebe yeLanga, khona-ke ukukhanya okukhishwa yilanga kuyavela.
izohambisana ne-axis eyinhloko yesibuko, njengoba kuboniswe esithombeni esingezansi. I-axis eyinhloko ingumugqa ocatshangelwayo oqonde phakathi nendawo ebusweni besibuko. Esifanekisweni esingezansi, i-axis eyinhloko ihambisana nephuzu eligxile (F) lesibuko.
Uma ushaya ubuso besibuko, umsebe ngamunye wokukhanya ugcwalisa umthetho wokubonakaliswa kokukhanya, lapho i-engeli yokwenzeka ifana ne-engeli yokubonakaliswa. Uma umugqa onamachashazi udwetshwe kusukela phansi kokukhanya okubonakalayo, yonke imigqa enamachashazi ihlangana endaweni efanayo, futhi leli phuzu libizwa ngokuthi i-focal point (F) yesibuko.
Iso lomuntu libona ukukhanya kuhamba endleleni eqondile kanye nokukhanya okubonakalayo njengokungathi kuvela endaweni eqondile yesibuko. Indawo eqondile yindawo yesithombe sento ekude kakhulu nobuso besibuko, isibonelo, ilanga nesithombe kungokoqobo.
Ubude obugxile besibuko esijiyile
Ubude be-focal (f) yibanga eliphakathi kwe-focal point (F) kanye nobuso besibuko. Iphuzu C liyiphuzu eliphakathi le-mirror curve. Ubude be-focal yesibuko esi-convex buyi-f (focal length = f = FQ) kanti i-radius ye-curve yesibuko esi-convex ingu-r (radius of curve = r = CQ = CP).
Umsebe ongenayo ushaya isibuko ku-P bese uboniswa yisibuko esijiyile, lapho ukukhanya okubonakalayo kubonakala sengathi kuvela endaweni yokugxila u-F. Umugqa onamachashazi i-CP umugqa ojwayelekile. Ukukhanya okungenayo kanye nokukhanya okubonakalayo kugcwalisa umthetho wokubonakaliswa kokukhanya lapho i-engeli yokwenzeka (θ) ilingana ne-engeli yokubonakalisa (θ), futhi le engeli ilingana ne-engeli yonxantathu i-PCQ (θ). I-engeli yonxantathu i-PCQ ifana ne-engeli yonxantathu i-CPF, ngakho-ke, unxantathu we-PFC unxantathu olinganayo. Ngenxa yokuthi unxantathu we-PFC unxantathu olinganayo, ubude be-PF bulingana nobude be-CF. Uma sicabanga ukuthi ububanzi besibuko buncane kune-radius yokugoba kwesibuko, 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 yokugoba kwesibuko kanye ne-FQ = f = ubude bokugxila kwesibuko. Ngakho-ke, kungaphethwa ngokuthi irediyasi yokugoba kwesibuko esijiyile (r) = ubude obungu-2x obuqondile (f) besibuko esijiyile. Ngokwezibalo:
r = 2f noma f = r / 2
Ukwakheka kwesithombe ngesibuko esijiyile
Izibuko ezigobile zingakha izithombe zangempela nezingokoqobo, kanti izibuko ezigobile zingakha izithombe ezibonakalayo kuphela. Ngokuphathelene nokwakheka kwesithombe sento ngezibuko ezigobile, kuchazwe ngokuningiliziwe esihlokweni sokwakheka kwesithombe ngesibuko esigobile.
Isithombe esibonakalayo
Uma isibuko esijiyile sibonakalisa ukukhanya okuza ebusweni besibuko esijiyile, isiqondiso sokukhanya okujiyile
Kubonakala sengathi kuvela endaweni egxile esibukweni esijiyile kanye nendawo ephakathi yokugoba kwesibuko esijiyile. Ngenxa yokuthi ukukhanya akudluli ngemuva kwesibuko esijiyile, isithombe esakhiwe siyisithombe esibonakalayo. Uma ubeka isikrini endaweni lapho kukhona isithombe esibonakalayo, asikho isithombe esikrinini. Isithombe esibonakalayo sikhona ngoba iso lomuntu libona imisebe yokukhanya ihamba iqonde futhi ibukeka sengathi imisebe ivela endaweni lapho isithombe esibonakalayo sikhona.
