Magawo oyambira a makondo owoneka bwino

Magawo oyambira a siginechaojambula zithunzi:

Tisanapezere mitundu yosiyanasiyana ya zithunzi, magawo azomwe amagwirira ntchitoZithunzi zowoneka bwinomwachidule. Makhalidwewa amaphatikizapo kulandira mauthenga, kuyankha kowoneka bwino, phokoso lofanana (Nep), kuwunika kwakanthawi, komanso kusazindikira. D *), kuchuluka kwa mphamvu, komanso nthawi yoyankha.

1. Kuukira kwa RD kumagwiritsidwa ntchito kumveketsa chidwi cha chipangizocho ku ma radication ma radiation. Imayimiridwa ndi chiwerengero cha chizindikiro chotulutsa chizindikiro. Khalidwe ili silimawonetsa phokoso la chipangizocho, koma chothandiza chokha chosintha magetsi opaleshoni ya electromagnemic kukhala injini yapano kapena yamagetsi. Chifukwa chake, imatha kukhala yosiyanasiyana ndi mafunde a zomwe zidachitika. Kuphatikiza apo, maluso oyankha ndi ntchito yovuta ya kukondera ndi kutentha kozungulira.

2. Kuyankha kowoneka bwino ndi gawo lomwe limadziwika kuti mgwirizano wamphamvu lamphamvu lomwe limakhala ndi zotchinga zowoneka bwino komanso zomwe zikuchitika. Makhalidwe owonera a spectical signal showments pamalo osiyanasiyana nthawi zambiri amafotokozedwa kuchuluka kwa "Cutctral Curve". Tiyenera kudziwa kuti mawonekedwe owoneka bwino kwambiri mu curve amakongoletsa kwathunthu, ndipo mawonekedwe ena azomwe amangomvera mosiyanasiyana pamapangidwe osiyanasiyana amafotokozedwa ndi zofunikira kwambiri pakuyandikana kwambiri.

3. Nyuzipepala yofanana ndi mphamvu yopepuka yomwe imafunikira pamene magetsi a signatur opangidwa ndi makina owoneka bwino ndi ofanana ndi Vousege ya chipangizocho. Ndiye chifukwa chachikulu chomwe chimatsimikizira kukula kwamphamvu komwe kungayesedwe ndi kafukufuku wa sing'anga, ndiye kuti, kuzindikira.

4. Kuzindikira mwachindunji ndi gawo lomwe limadziwika kuti limadziwika kuti limapangidwa ndi zithunzi zaphindu. Imayimira njira yotsika kwambiri yomwe imachitika chifukwa cha kuchuluka komwe kumayesedwa ndi chotchinga siginecha. Mtengo wake umatha kusiyanasiyana malinga ndi zojambula zoyendetsedwa ndi zojambula za kugwedezeka kwa chizindikiro cha chizindikiro chowala (kutentha kotereku kozungulira, kuthirako kwamitundu, etc.). Chophimba chonyansa cha Bandwodth, chowongolera chotchinga chowoneka bwino, chocheperako chofanana ndi mphamvu nep, komanso zomwe zimapangitsa kuti chidwi ndi chizindikiritso. Kuzindikira kwapamwamba kwambiri kwa chofufumitsa kumatanthauza kuti ndikoyenera kuzindikira kwa anthu ambiri ofooka.

5. Amatanthauziridwa ngati chiwerengero cha kuchuluka kwa "mayankho" opangidwa ndi Phondomon omwe ali pachiwopsezo chiwerengero cha zithunzi zomwe zili pamwamba pazinthu za zithunzi. Mwachitsanzo, kuwunika kwa zikwangwani zopepuka kumagwira ntchito pa Photon Kutulutsa, mphamvu ya kuchuluka kwa Photoelectrons yomwe imapangidwa kuchokera pamwamba pa nambala ya zithunzi za zithunzi zomwe zimayesedwa. Mu wotchinga siginecha yogwiritsa ntchito pn Junction Semiconductor zinthu monga momwe zimawerengedwa ndikugawa kuchuluka kwa magetsi a electron yopangidwa ndi chiwerengero cha zithunzi zojambulajambula. Choyimira china chofala cha kuchuluka kwa njira yodziwika ya signal signal ndikugwiritsa ntchito zojambulazo za RD.

6. Nthawi yoyankha ndi gawo lofunikira kuti muzindikire kuthamanga kwa kawonedwe kwa signal kusinthidwe koyenera kwa chizindikiro. Pamene chizindikiritso chopepuka chimasinthidwa kukhala mawonekedwe a chowuma, kukula kwa mawonekedwe am'magetsi omwe amapangidwa kuti "atuluke" nthawi yoyambira, ndikubwerera "zero. Pofuna kufotokozera mayankho omwe amapezeka pakusintha kwakukulu kwa chizindikiritso chowala, nthawi yomwe kukula kwa magetsi okwanira 100% kumatchedwa "nthawi yomwe 10%" imatchedwa "nthawi yowonongeka" kapena "nthawi yowonongeka".

7. Pamafunika kutulutsa kwachotchinga chowoneka bwinokukhala wofanana ndi kuchuluka kwa kukula kwa chizindikiro cham'miyeso. Nthawi zambiri zimafotokozedwa kuti kupatuka kwa kuchuluka kwa malo owonjezera omwe abweretsa mkati mwa mitundu yolowera kowoneka ngati njira yoyatsira siyi.
