Kana chinhu chiri kudivi rimwe chete regirazi rakamonana, iro girazi rakamonana rinogona kuumba mufananidzo wechinhu ichocho. Kana nzvimbo yechinhu chiri kudivi rimwe chete regirazi rakamonana ichizivikanwa, ungadhirowa sei mufananidzo wechinhu ichocho? Kuti ujekese izvi, ngatitii chinhu chiri kuruboshwe. lenzi yakamoneredzwa sezvakaratidzwa mumufananidzo uri pazasi.
Mashoko ekuwedzera:
Mutsetse weorenji = lenzi yakakomberedzwa
Mutsetse webhuruu = axis ye lenzi
Museve (girini) = chinhu
F1 = kureba kwefocal 1 na F2 = kureba kwefocal 2
Mifananidzo yemumvuri yezvinhu inowanikwa nekudhirowa zvese chiedza chemwenje dzinopfuura nepakati pechinhu, asi izvi hazvigoneki nekuti pachava nemitsetse yakawanda inomiririra mwenje. Kuti zvive nyore, mwenje mishoma chete ndiyo inosarudzwa kumiririra mwenje yese inopfuura nepakati pechinhu. Tichifunga kuti chiitiko ichi chinosanganisira kudzorwa kwechiedza Maka mutemo wekusachinja chiedza inofanira kutevedzwa pakudhirowa kuumbwa kwemumvuri.
Marara matatu echiedza kana marara akakoshalenzi ine convex
Chiedza chakakosha 1:
Ray 1 kana chiedza 1 chinouya kune lenzi yakatenderedza girazi chinoratidzwa sechinofanana ne axis yelenzi uye inobata kumucheto wepamusoro wechinhu chacho, yobva yadzoserwa negirazi re convex uko mwenje wechiedza wakadzoserwa unofanira kupfuura nepakati pacho nzvimbo yekutarisa 2Mwaranzi wechiitiko nemwaranzi yakadzorwa zvinoratidzwa zvinofanira kuzadzisa mutemo wekusachinja chiedza.
Chiedza chakakosha 2:
Ray 2 kana kuti rambi rechiedza 2 rinouya richinanga kune lenzi ine convex rinoratidzwa serinofanira kupfuura nepakati nzvimbo yekutarisa 1 uye inobata kumucheto wepamusoro wechinhu, yobva yadzoserwa negirazi re convex uko mwenje wechiedza wakadzoserwa unofanirwa kuenderana ne axis huru. Mwaranzi wechiitiko nemwaranzi wakadzoserwa unoratidzwa zvinofanirwa kusangana mutemo wekusachinja chiedza.
Chiedza chakakosha 3:
Ray 3 kana kuti rambi rechiedza 3 rinouya richinanga kune lenzi ine convex rinoratidzwa serinofanira kupfuura nepakati nzvimbo inopindirana lenzi ine convex ne lenzi ine axis uye inobata kumucheto wepamusoro wechinhu chacho, ipapo mwenje unopfuudzwa.
Kuumbwa kwemumvuri (mwaranzi miviri yakakosha)
Kuumbwa kwemumvuri wechinhu kunogona kuratidzwa uchishandisa mwenje miviri chete, sezvakaratidzwa mumufananidzo uri pazasi. Kana mwenje miviri kana mwenje miviri yakakosha ikashandiswa, pane mifananidzo mitatu inogona kuratidzwa yekuumbwa kwemumvuri.
Misi chaiyo 1 ne2
Misi chaiyo 1 ne3
Misi chaiyo 2 ne3
Mufananidzo wekuumbwa kwemufananidzo wechinhu uchishandisa mwenje miviri chete unofanirwa kugadziriswa kuti uenzane nedaro rechinhu kubva kune lenzi yakapinza. Kana daro rechinhu kubva kune lenzi yakapinza riri seriri mumufananidzo uri pamusoro, pane nzira nhatu dzekudhirowa mufananidzo uchishandisa mwenje miviri chete. Kana daro rechinhu kubva kune lenzi yakapinza rakasiyana nemufananidzo uri pamusoro, semuenzaniso, chinhu chiri pakati penzvimbo yekutarisa nepakati pekona, saka panogona kunge pasina nzira nhatu dzekudhirowa mufananidzo, panogona kunge paine nzira mbiri chete dzekudhirowa.
Kana ukadhirowa kuumbwa kwemufananidzo uchishandisa lenzi ine convex, unogona kusarudza nzira imwe chete uye haufanirwe kushandisa nzira mbiri kana nhatu.
Kuumbwa kwemufananidzo (mwaranzi mitatu yakakosha)
Kuumbwa kwemumvuri wechinhu kunogona kuratidzwa uchishandisa mwenje mitatu kana maranzi matatu akakosha, sezvakaratidzwa mumufananidzo uri pazasi.
Kana daro rechinhu kubva pagirazi re convex risiri seriri mumufananidzo uri pamusoro, semuenzaniso chinhu chiri pakati pegirazi re convex nepfungwa yekutarisa, kana chinhu chiri pakati penzvimbo yekutarisa nepakati pekukombama kwegirazi re convex, saka hazvina chokwadi kuti kuumbwa kwemufananidzo wechinhu kunogona kutsanangurwa uchishandisa mikana mitatu kana nzira nhatu sezviri mumufananidzo uri pamusoro. Zvingave kuti pane mikana miviri chete kana nzira mbiri dzekudhirowa kuumbwa kwemufananidzo. Ndapota tarisai muenzaniso wemufananidzo wekuumbwa kwemufananidzo wechinhu negirazi re convex, uko daro rechinhu kubva pagirazi re convex rinosiyana, mumusoro wenyaya. mufananidzo wegirazi re convex.
