Astronomical telescope yog dab tsi?

Astronomical telescope yog cov cuab yeej tseem ceeb rau kev soj ntsuam lub cev ntuj ceeb tsheej thiab khaws cov ntaub ntawv xov xwm hnub qub.Txij li thaum Galileo tau tsim thawj lub koob yees duab hauv xyoo 1609, lub koob yees duab tau tsim tsis tu ncua.Los ntawm optical band mus rau tag nrho cov band, los ntawm hauv av mus rau qhov chaw, lub peev xwm soj ntsuam ntawm lub tsom iav raj yog ua kom muaj zog thiab muaj zog, thiab ntau thiab ntau lub cev ntawm lub cev yuav ntes tau.Tib neeg muaj telescopes hauv electromagnetic yoj band, neutrinos, gravitational tsis, cosmic rays thiab lwm yam.

Keeb kwm kev loj hlob:

Telescope keeb kwm los ntawm tsom iav.Tib neeg pib siv tsom iav li 700 xyoo dhau los.Nyob ib ncig ntawm 1300 ad, Italians pib ua cov tsom iav nyeem ntawv nrog cov lo ntsiab muag convex.Nyob ib ncig ntawm 1450 ad, myopia tsom iav kuj tshwm sim.Xyoo 1608, tus kws tshaj lij ntawm H. Lippershey, lub tuam txhab Dutch eyewear, nrhiav pom tias los ntawm kev muab ob lub lo ntsiab muag ua ke, nws pom tau meej meej pom qhov deb.Xyoo 1609, thaum Galileo, tus kws tshawb fawb Italian, tau hnov ​​​​txog qhov kev tsim khoom, nws tam sim ntawd ua nws tus kheej tsom iav thiab siv nws los soj ntsuam cov hnub qub.Txij thaum ntawd los, thawj astronomical telescope tau yug los.Galileo tau soj ntsuam qhov tshwm sim ntawm hnub ci, lunar craters, satellites ntawm Jupiter (Galileo satellites) thiab cov txiaj ntsig thiab poob ntawm Venus nrog nws lub tsom iav, uas txhawb nqa Copernicus txoj kev xav heliocentric.Galileo lub telescope yog tsim los ntawm lub hauv paus ntsiab lus ntawm refraction ntawm lub teeb, yog li nws yog hu ua refractor.

Nyob rau hauv 1663, Scottish astronomer Gregory tau ua ib daim iav Gregory los ntawm kev siv lub hauv paus ntsiab lus ntawm lub teeb, tab sis nws tsis nrov vim yog cov khoom siv tsis paub tab.Xyoo 1667, tus kws tshawb fawb Askiv Newton tau txhim kho Gregory lub tswv yim thiab ua ib daim iav Newtonian.Nws qhov aperture tsuas yog 2.5cm, tab sis qhov kev nthuav dav yog ntau dua 30 npaug.Nws kuj tshem tawm cov xim sib txawv ntawm lub tsom iav raj refraction, uas ua rau nws ua tau zoo heev.Xyoo 1672, Fab Kis Fab Kis Cassegrain tau tsim cov Cassegrain reflector feem ntau siv los ntawm cov iav concave thiab convex.Lub koob yees duab muaj qhov ntev focal ntev, lub lens luv luv, qhov loj loj thiab cov duab meej;Nws tuaj yeem siv los yees duab lub cev loj thiab me me hauv lub tshav pob.Lub Hubble telescope siv hom tsom iav tsom iav zoo li no.

Nyob rau hauv 1781, British astronomers W. Herschel thiab C. Herschel nrhiav tau Uranus nrog tus kheej-ua 15 cm aperture daim iav.Txij thaum ntawd los, astronomers tau ntxiv ntau lub luag haujlwm rau lub koob yees duab kom nws muaj peev xwm ntawm spectral tsom xam thiab lwm yam.Xyoo 1862, American astronomers Clark thiab nws tus tub (A. Clark thiab A. g. Clark) tau tsim lub 47 cm aperture refractor thiab thaij duab ntawm Sirius cov hnub qub.Xyoo 1908, American astronomer Haier tau coj kev tsim kho ntawm 1.53 meter aperture daim iav kom ntes cov spectrum ntawm Sirius tus khub hnub qub.Xyoo 1948, Haier telescope tau ua tiav.Nws qhov aperture ntawm 5.08 meters yog txaus los soj ntsuam thiab txheeb xyuas qhov kev ncua deb thiab pom meej tshaj tawm ntawm lub cev nyob deb ntawm ntuj ceeb tsheej.

Xyoo 1931, German optician Schmidt ua Schmidt telescope, thiab nyob rau hauv 1941, lub Soviet astronomer mark sutov ua lub cim sutov Cassegrain reentry daim iav, uas enriched hom telescopes.

Niaj hnub no thiab niaj hnub no, astronomical telescopes tsis txwv rau optical bands.Xyoo 1932, American Radio Engineers tau tshawb pom lub xov tooj cua hluav taws xob los ntawm qhov chaw ntawm Milky Way galaxy, cim lub hnub yug ntawm xov tooj cua astronomy.Tom qab tso tawm cov neeg tsim satellites hauv xyoo 1957, lub koob yees duab hauv qhov chaw tau vam meej.Txij li thaum lub xyoo pua tshiab, lub tsom iav raj tshiab xws li neutrinos, cov teeb meem tsaus ntuj thiab cov nthwv dej gravitational yog nyob rau hauv ascendant.Tam sim no, ntau cov lus xa los ntawm lub cev xilethi-aus tau dhau los ua cov nyiaj txiag ntawm cov kws tshawb fawb, thiab tib neeg lub zeem muag tau dhau los ua qhov dav thiab dav.

Thaum lub Kaum Ib Hlis 2021, tom qab lub sijhawm ntev ntawm kev tsim kho engineering thiab kev sib koom ua ke, qhov kev cia siab ntau ntawm James Webb Space Telescope (JWST) thaum kawg tuaj txog ntawm qhov chaw tso tawm nyob rau hauv Fabkis Guiana thiab yuav raug tso tawm nyob rau yav tom ntej.

Ua hauj lwm hauv paus ntsiab lus ntawm astronomical telescope:

Lub hauv paus ntsiab lus ua haujlwm ntawm astronomical telescope yog tias lub hom phiaj lens (convex lens) tsom cov duab, uas yog amplified los ntawm eyepiece (convex lens).Nws yog tsom los ntawm lub hom phiaj lens thiab ces amplified los ntawm eyepiece.Lub hom phiaj lens thiab eyepiece yog ob chav sib cais, thiaj li los txhim kho cov duab zoo.Ua kom lub teeb pom kev hauv ib cheeb tsam, kom tib neeg tuaj yeem pom cov khoom tsaus thiab cov ntsiab lus ntxiv.Dab tsi nkag rau hauv koj ob lub qhov muag yog yuav luag thaum lub teeb sib luag, thiab qhov koj pom yog cov duab xav txog qhov loj ntawm lub qhov muag.Nws yog txhawm rau nthuav lub kaum sab xis me me ntawm cov khoom nyob deb raws li qee qhov kev nthuav dav, kom nws muaj lub kaum sab xis qhib loj hauv qhov chaw duab, kom cov khoom uas tsis tuaj yeem pom lossis qhov txawv ntawm qhov muag liab qab yuav pom tseeb thiab txawv.Nws yog ib qho kev kho qhov muag uas ua rau qhov xwm txheej sib npaug ntawm cov nqaj emitted nyob rau hauv parallel los ntawm lub hom phiaj lens thiab eyepiece.Feem ntau muaj peb hom:

1, Refraction telescope yog lub tsom iav nrog lub lens raws li lub hom phiaj lens.Nws tuaj yeem muab faib ua ob hom: Galileo telescope nrog concave lens li eyepiece;Kepler telescope nrog convex lens li eyepiece.Vim hais tias cov chromatic aberration thiab spherical aberration ntawm ib lub hom phiaj ntawm ib lub lens yog qhov hnyav heev, niaj hnub refraction telescopes feem ntau siv ob lossis ntau pawg lens.

2, Lub tsom iav tsom iav yog lub tsom iav tsom iav nrog daim iav concave raws li lub hom phiaj lens.Nws tuaj yeem muab faib ua Newton telescope, Cassegrain telescope thiab lwm yam.Lub ntsiab kom zoo dua ntawm lub telescope reflecting yog tias tsis muaj chromatic aberration.Thaum lub hom phiaj lo ntsiab muag txais ib qho paraboloid, lub spherical aberration kuj raug tshem tawm.Txawm li cas los xij, txhawm rau txo qis kev cuam tshuam ntawm lwm yam aberrations, qhov muaj kev pom yog me me.Cov khoom siv rau kev tsim cov iav tsuas xav tau me me expansion coefficient, tsis tshua muaj kev ntxhov siab thiab sib tsoo yooj yim.

3 、 Catadioptric telescope yog ua raws li daim iav kheej kheej thiab ntxiv nrog cov ntsiab lus refractive rau kev kho aberration, uas tuaj yeem zam kev ua haujlwm loj aspherical nyuaj thiab tau txais cov duab zoo.Lub nto moo tshaj plaws yog Schmidt telescope, uas muab Schmidt kho phaj rau ntawm qhov chaw ntawm daim iav kheej kheej.Ib qhov chaw yog lub dav hlau thiab lwm qhov yog me ntsis deformed aspherical nto, uas ua rau lub hauv paus ntawm lub nqaj converge me ntsis thiab lub peripheral feem diverge me ntsis, tsuas yog kho lub spherical aberration thiab coma.
