25/07/24Emhlabeni wanamuhla oqhutshwa izithombe, amakhamera akhona yonke indawo—kusuka ku-smartphone ephaketheni lakho kuya kumathuluzi asezingeni eliphezulu kumalebhu ocwaningo. Kodwa nakuba wonke amakhamera ethwebula izithombe, akuwona wonke akhiwe ngenjongo efanayo noma ngokunemba engqondweni.
Ikhamera yesayensi ihluke kakhulu kukhamera ongayisebenzisela ukuvakasha noma inkundla yezokuxhumana. Ngaphandle komehluko kuma-megapixel noma ukucija, amakhamera esayensi aklanywa njengamathuluzi okulinganisa nokuhlaziya, athwebula idatha, hhayi nje izithombe.
Ukuqonda ukuthi ahluke kanjani kumakhamera abathengi mayelana nobuchwepheshe bezinzwa, ukwethembeka kwesithombe, kanye nomklamo oqondene nohlelo lokusebenza kubalulekile ekukhetheni isistimu yokuthwebula elungile yezidingo zakho. Kungakhathaliseki ukuthi usebenza kusayensi yempilo, isayensi yezinkanyezi, i-spectroscopy, noma ukukhiqizwa kwe-semiconductor, ukwazi ukuthi lezi zinhlobo ezimbili zamakhamera zihluka kanjani kusiza ukuqinisekisa ukuthi imiphumela yakho yokuthwebula ayigcini nje ngokuhlaba umxhwele ngokubukeka kodwa futhi isemthethweni ngokwesayensi.
Iyini Ikhamera Yesayensi?
Ikhamera yesayensi ayilona nje ithuluzi lokuthwebula izithombe—iyithuluzi elinembayo lokuthola, ukulinganisa, nokuhlaziya amafothoni. Amakhamera esayensi aklanyelwe ukulawula, ukunemba, ukuphindaphinda, nobuqotho bedatha.
Izici ezibalulekile zamakhamera wesayensi zihlanganisa
● Isilinganiso se-photon sobuningi (hhayi nje ukuthwebula isithombe sobuhle)
