Maonero eJomethri nePhysical Optics: Pfupiso Yakakwana
Optics, bazi refizikisi rinobata nekudzidza kwechiedza uye kudyidzana kwacho nezvinhu, rinopa ruzivo rwakadzama nezvenyika yechisikigo. Rinopatsanurwa kuita zvikamu zviviri zvikuru: geometric optics ne physical optics, rimwe nerimwe richitaura nezvemaitiro echiedza. Chinyorwa chino chinotarisa misimboti inokosha, zviitiko, uye mashandisirwo e geometric ne physical optics, zvichiratidza kuti minda iyi inoshanda sei kuti ijekese kuoma kwechiedza.
Optics yeGeometric: Kuswedera kweRay
Maoptical geometric, dzimwe nguva anonzi maoptical ray, anoita kuti kudzidza chiedza kuve nyore nekuchiona semuunganidzwa wemwaranzi inofamba mumitsara yakatwasuka. Kufungidzira uku kunoshanda kana saizi yezvinhu zvinodyidzana nechiedza yakakura kupfuura urefu hwewavelength yechiedza pachacho. Maoptical geometric anotongwa nenheyo nemitemo yakati wandei:
1. Kupararira kweChiedza kwakabatana: Munzvimbo imwe chete, chiedza chinofamba mumitsara yakatwasuka. Iyi nheyo ndiyo hwaro hwekuongorora zviitiko zvakaita semimvuri uye kuumbwa kwemifananidzo nemagirazi.
2. Kufungisisa: Kana chiedza chikasangana nechinhu chinopenya, senge girazi, chinodzokera shure. Mutemo wekufungisisa unoti kona yechiitiko (θi) yakaenzana nekona yekuratidzira (θr). Iyi nheyo yakakosha pakugadzira zvishandiso zve optical zvakaita se periscopes uye mashandisirwo akawanda ezuva nezuva.
3. Kupatsanura: Kukombama kwechiedza pachinopfuura kubva pane imwe nzira kuenda kune imwe kunotsanangurwa nemutemo waSnell. Unotaura kuti chiyero chemasine emakona echiitiko nekupatsanura chakaenzana nechiyero chekumhanya kwekupararira muzvikamu zviviri. Pamasvomhu, chinoratidzwa se:
\(n_1 \cdot \sin(\theta_1) = n_2 \cdot \sin(\theta_2)\)
apo \(n_1\) uye \(n_2\) zviri zviratidzo zvekurefractory zve media yacho. Kurefractory kwakakosha mumalenzi, maprism, uye kudzidza nezvezviitiko zve optical zvakaita semarainbow nemamirages.
4. Maekisioni eLenzi neMagirazi: Hukama huripo pakati pedaro rechinhu (\(d_o\)), daro remufananidzo (\(d_i\)), uye urefu hwefocal (\(f\)) hwemalenzi nemagirazi hunopiwa neekisioni/girazi:
\(\frac{1}{f} = \frac{1}{d_o} + \frac{1}{d_i}\)
Iyi equation ndiyo inoumba hwaro hwekugadzira zvishandiso zve optical zvakaita semakamera, materesikopu, uye maikorosikopu.
5. Kuratidzwa Kwemukati Kwese: Kana chiedza chichifamba kubva pane chinhu chine refractive index yakakwira kuenda kune chine refractive index yakaderera, kupfuura imwe angle yakakosha, chiedza chose chinodzoserwa zvakare muchinhu chekutanga. Ichi chiitiko ndicho musimboti uri shure kwefiber optics inoshandiswa mukutaurirana.
Kuona kweGeometric optics kunobatsira zvikuru mukugadzira zvishandiso zvakasiyana-siyana zve optical uye masisitimu atinoshandisa muhupenyu hwezuva nezuva. Kungave kuri kutarisa kamera, kugadzira magirazi emaziso, kana kuronga ma laser, nyore uye kushanda kwe ray approximation zvinopa mhinduro dzinoshanda kumatambudziko akaomarara.
Optics yemuviri: Mafungu eChiedza
Kunyange zvazvo geometric optics ichivimba nemuenzaniso wemwaranzi, physical optics inotarisa hunhu hwemafungu echiedza. Nzvimbo iyi inova yakakosha pakubata nezviitiko zvinobva muhunhu hwemafungu echiedza, zvakaita sekupararira kwechiedza uye kupindira.
1. Dzidziso yeMafungu eChiedza: Yakataurwa naChristiaan Huygens uye yakasimbiswa nekuenzanisa kwaJames Clerk Maxwell, dzidziso yemafungu inotsanangura chiedza semafungu emagetsi. Kunzwisisa uku kwakakosha pakutsanangura maitiro echiedza pachikero zvinoenderana nehurefu hwacho hwewavelength.
2. Kupindirana: Kana mafungu maviri kana kupfuura echiedza akabatana, anobatana kuti aumbe mafungu anobuda. Nheyo ye superposition inotsanangura chiitiko ichi, zvichikonzera kupindirana kunovaka (chiedza chakawedzerwa) kana kupindirana kunoparadza (chiedza chadzikira). Izvi zvinoonekwa mumapatani anogadzirwa nemafirimu matete, mafirita ekupindira, uye mumashandisirwo akaita se holography.
3. Kupatsanurwa: Kana chiedza chikasangana nechipingamupinyi kana mukaha wakaenzana nehukuru hwacho, chinokotama chakachitenderedza. Kukotama uku nekupararira kwemafungu echiedza kunotungamira kumapatani ekupatsanurwa, zvakakosha pakunzwisisa simba rekugadzirisa remateresikopu nemamaikorosikopu. Kuedza kwakakurumbira kwemukaha wakapetwa kaviri kwakaitwa naThomas Young kwakaratidza hunhu hwemafungu echiedza kuburikidza nemapatani ekupatsanurwa uye ekupindira.
4. Polarization: Mafungu echiedza anogona kutenderera munzira dzakasiyana, asi polarization inoderedza kutenderera uku kuenda kune imwe nzira. Chiitiko ichi chinoshandiswa mugirazi dzezuva dzine polarized, liquid crystal displays (LCDs), uye stress analysis muzvinhu zvinoonekera.
5. Quantum Optics: Panosangana physical optics ne quantum mechanics pane quantum optics, iyo inoongorora kudyidzana kwema photon nezvinhu. Izvi zvinosanganisira zviitiko zvakaita se photon entanglement, quantum coherence, uye mashandisirwo mumatekinoroji ari kubuda akadai se quantum computing ne cryptography.
Mashandisirwo uye Kubatanidzwa
Kudyidzana pakati pe geometric ne physical optics kunoonekwa mukushandiswa kwakasiyana-siyana uko mamodheru echiedza e ray nema wave anodiwa. Semuenzaniso:
– Zvishandiso Zvekuona: Zvishandiso zvakaita semamaikorosikopu nemateresikopu zvinoshandisa misimboti yejometri pakuwedzera, asi simba razvo rekugadzirisa rinodzorwa nemiganhu ye diffraction, pfungwa inobva ku physical optics.
– Fiber Optics: Dhizaini yetambo dze fiber optic inoshandisa kuratidzwa kwemukati kwese (geometric optics) uku ichivimbisa kurasikirwa kushoma kwechiratidzo kuburikidza nepfungwa dzekupararira kwemafungu (physical optics).
- Masisitimu Emifananidzo: Masisitimu emazuva ano emifananidzo, kubva pamidziyo yekurapa yakaita semichina yeMRI kusvika kumakamera edhijitari akareruka, achishandisa malenzi (geometric optics) uye masensa akagadziriswa kuti akwanise kupindira kwechiedza uye diffraction (physical optics).
– Tekinoroji yeLaser: MaLaser anoshanda zvichienderana nepfungwa dzinobva kumatunhu ese ari maviri; kuumbwa kwemwaranzi kwakabatana kunotevera geometric optics, nepo kugadzirwa kwechiedza kunosanganisira quantum mechanics uye mafungu emhepo.
mhedziso
Zvese zviri zviviri geometric ne physical optics zvinopa maturusi akakosha ekunzwisisa nekushandisa chiedza. Geometric optics, nekutarisa kwayo kwakananga kwemwaranzi, inopa mhinduro dzinonzwisisika dzezvishandiso zvezuva nezuva zve optical. Kusiyana neizvi, physical optics inoratidza hunhu hwechiedza hwakadzika, ichitsanangura zviitiko zvakaoma uye ichigonesa matekinoroji epamusoro. Pamwe chete, minda iyi inokurudzira hunyanzvi mune sainzi, mainjiniya, uye tekinoroji, ichiratidza hunhu hwakawanda hwechiedza uye basa rayo guru mukunzwisisa kwedu zvakasikwa. Kungave kugadzira lenzi yakapfava kana kuongorora duality yemafungu-particle emaphotons, nzvimbo dze geometric ne physical optics dzinoramba dzichijekesa nzira yedu yekuenda mberi.
