Tsis zoo siv
Kev siv ntawm kev sib xws aperture tuaj yeem txo qhov loj thiab qhov hnyav ntawm lub aperture loj. Tus kheej lossis cov dej ntws tsis yooj yim siv yog qhov nyuaj rau kev pom ntawm cov kab ke thiab txhim kho cov duab zoo. Piv nrog ua tau zoo me ntsis lossis spherical qhov chaw, kho qhov muag tsis pub luam tawm muaj cov kev tsim ywj pheej. Daim ntawv tsim no ib ob-daim iav sparse aperture telescope. Daim iav tseem ceeb yog ua los ntawm peb daim iav sub-tau npaj rau hauv Golay3 kev teeb tsa thaum lub Koom Haum Me Nyuam Yaus Cov txiaj ntsig qhia tau hais tias tag nrho cov chaw pom nce ntxiv rau 0. 32 degree hauv daim iav kho qhov muag thaum lub Koom Haum Me Nyuam Yaus siv cov kev ywj pheej. Cov duab zoo ua tau raws li cov cai ua nws txoj haujlwm hloov pauv.

1. Pib
Txhawm rau txhim kho cov kev daws teeb meem ntawm lub tshuab tsom iav, lub aperture ntawm cov kho qhov muag yuav tsum tau nce. Txawm li cas los xij, kev loj hlob ntawm loj aperture kho kho kho kho kho tau puas muaj txwv, cov nqi tsim khoom, ntim, qhov hnyav, qhov hnyav, qhov hnyav, qhov hnyav, qhov hnyav, qhov hnyav thiab lwm yam. Kev hais txog lub tsom iav [1] yog ib hom kev ntsuas kho qhov system uas siv kev cuam tshuam rau kev faib tawm thiab kev sib cuam tshuam ntawm aperture loj [2,3]. Lub luminous thaj tsam ntawm tag nrho cov kab ke yog me dua li ntawm ib qho loj loj. Lub kaw lus lub ntim thiab loj txo. Tab sis cov ntaub ntawv tau yog qhov tseeb sib npaug ntawm qhov ntawd ntawm ib qho loj me aperture system.
Muaj ob hom kev rau kev sib zog HTTse telescopes. Ib qho yog multi-multip telescope (mult) uas thawj daim iav yog ua los ntawm ob peb daim iav me me. Golay6 Kev Sib Tw Aperture Telescope ntawm Boeing Svs Tuam Txhab Company [4] yog cov multi-mody forces. Lwm tus yog ntau lub tsom iav ntau lub tsom iav (MTT) tias ob peb lub tsom iav ua kom muaj kev sib cav sib ceg, txhua tus nrog nws tus kheej thib ob nrog cov thib ob. Nws cov piv txwv yog yoog kev soj ntsuam golay3 Optical satellite (argos) ntawm Massachusetts Institute of Technology (MIT) [5]. Txawm li cas los xij, cov kab ke no feem ntau siv spherical lossis asferic ncaj, uas muaj cov kev txwv nyob rau hauv tau txais ib daim teb loj ntawm kev pom thiab cov duab zoo dua.
Piv nrog cov tsoos nto hom, tshwj xeeb tshaj yog rau lub tshuab kho qhov muag uas muaj kev pom zoo. Cov dawb dawb muaj ntau tsim kev ywj pheej [6]. Nws muaj lub peev xwm muaj zog los kho cov aberration. Yog li ntawd, kev siv cov kev ua kom dawb muaj peev xwm ua kom pom cov duab zoo thiab tau txais daim teb loj ntawm [7].
Hauv daim ntawv no, ib qho tshiab golay3 sib ncoo aperture ntau-daim iav tsom iav tsim qauv tsim nrog cov chaw dawb tau nthuav tawm. Lub kaw lus daim iav tseem ceeb yog qhov dawb dawb, thiab daim iav thib ob yog tsim nrog hyperboloid.
2. Theoretical keeb kwm yav dhau
Golay3 kev sib zog Aperture yog qhia hauv daim duab 2.1. Cov chaw ntawm peb ntu-apertures yog nyob rau ntawm peb kab ntawv ntawm cov duab peb sab ib txwm. Lub voj voos me tshaj plaws ntawm lub voj voog ntawm sub-apertures yog hu ua qhov txuas rau Aperture. Qhov kev sau ua ke [8] ntawm ib qho kev sib xws icerture system txhais tau hais tias yog qhov sib piv ntawm tag nrho cov tsom iav 'thaj chaw rau ntawm lawv ib puag ncig aperture. Golay3 sparse aperture kho qhov muag uas kaw lus sau qhov system [9] yog
Daim duab 2.1 Qhov txheej txheem ntawm Golay3 sparse aperture kho qhov muag ua haujlwm
Ntawm no d sawv cev txoj kab uas hla ntawm sub-aperture, thiab d sawv cev txoj kab uas hla ntawm lub voj voog. Qhov kev sib sau ua ke qhia tias muaj peev xwm ntawm aperture mus sau lub teeb.
Lub tub ntxhais kawm muaj nuj nqi ntawm kev sib txawv aperture kho qhov system tuaj yeem qhia tau tias yog qhov kev ntseeg ntawm ib qho kev ua tiav ntawm ib qho kev ua haujlwm ntawm kev ua haujlwm ntawm ib qho kev ua haujlwm ntawm kev ua haujlwm ntawm ib qho kev ua haujlwm ntawm kev ua haujlwm ntawm kev ua haujlwm ntawm kev ua haujlwm ntawm ib qho kev ua haujlwm tiav
Los ntawm kev paub ntawm cov ntaub ntawv optics, cov tub ntxhais kawm muaj nuj nqi, taw tes sib kis ua haujlwm (PSF) thiab hloov chaw ua haujlwm muaj cov kev sib raug zoo hauv qab no, raws li qhia hauv daim duab 2.2:
Daim duab.2.2 Kev sib raug zoo ntawm cov tub ntxhais kawm txoj haujlwm, taw tes diffulion muaj nuj nqi thiab hloov ua haujlwm
Kev hloov pauv hloov (MTF) ntawm Golay3 sparse aperture kho qhov muag ntsuas yog[10] :
Ntawm no MTFlub hauv pausyog kev hloov pauv kev hloov haujlwm ntawm cov sub-aperture, thiab cov lus qhia yog:
Nws tuaj yeem pom los ntawm cov qauv uas ua ke ntawm ntau sub-aperture mtf hauv MTF ntawm tag nrho cov kev sib zog agerture system. MTF nkhaus kuj tseem yog ib qho ntawm cov qauv tseem ceeb los ntsuas qhov kev xav txog qhov ua tau zoo.
Hauv kev siv cov kev siv, ib qho ob-daim iav system feem ntau yog siv los tsim lub tsom iav. Golay3 kev sib zog aperture ntau daim iav tsom iav generescope tsim nyob rau hauv daim ntawv no tau muab los ntawm ob-daim iav system. Thawj daim iav ntawm ob-daim iav system tau hloov los ntawm Golay3 sparse aperture. Qhov kev teeb tsa ntawm ob-lub iav system tau qhia hauv Daim duab.2.3.
Daim duab2.3 Kev teeb tsa ntawm ob-daim iav system
Ob-daim iav piv ntawm daim iav thib ob thiab daim iav thib ob:
Nws tuaj yeem tau txais los ntawm kev siv cov mis ntawm Gaussian Optics:
Ntawm no r1thiab r2yog lub vojvoog ntawm curvature ntawm thawj daim iav m1thiab theem nrab daim iav m2feem xyuam.
Los ntawm kev paub ntawm geometry, peb tuaj yeem paub:
Firstly, lub apertature, tus txheeb ze aperture, txheeb ze aperture ntawm thawj daim iav thiab lub focal point projection Δ ntawm cov kab ke raug txiav txim siab los laij thiab. Tom qab ntawd L2, D, R1 thiab R2 tuaj yeem suav raws cov mis (5), (8) thiab (9). Thaum kawg, raws li qhov kev txiav txim siab thib peb aberration txoj kev xav, cov duab coefficients 𝑒𝑒 {}}}} ntawm thawj daim iav tau raug suav.
Txawm li cas los xij, thaj teb ntawm kev pom ntawm cov kab ke kis xwm txheej yog me me vim tias muaj kev cuam tshuam ntawm coma thiab astigmatism. Kev siv dawb dawb haum nrog rau Zernike los tsim cov golay3 sparse aperture tuaj yeem nce teb ntawm cov kab ke thiab txhim kho qhov kev xav zoo. Daim ntawv ntawm Freeform Dege yog raws li hauv qab no:
Muaj zlnyog zernike polynomial:
Yog li ntawd, cov Zerer Polynomials tuaj yeem sau ua:
Zernike polynomials muaj ob qhov zoo. Ib qho yog txuas ntxiv thiab orthogonal nyob rau hauv chav nyob lub voj voog sau, thiab coefficients ntawm tus polynomials muaj kev ywj pheej. Thib ob, nws muaj kev sib raug zoo nrog kev sib raug zoo ntawm yoj kev ua haujlwm, uas yooj yim los tsim kev sib raug zoo ntawm kev ua kom dawb thiab yoj aberration.
3. Simulations
Daim ntawv no tsim ib qho ob-daim iav system. Lub qhov rooj nkag rau cov tub ntxhais lub taub hau yog 25 0 hli thiab f ntawm kev pom yog ± 0.16 degree. Qhov ntau ntawm wavelength yog 486 ~ 656nm. Qhov txoj kab uas hla ntawm kev sib cav aperture Sub-aperture yog 52mm. Yog li cov kev sib sau ntawm lub system yog 51.92%. Tom qab xam cov qauv pib thiab ua kom zoo nrog zemax. Cov txheej txheem zaum kawg ntawm lub system yog qhia hauv tab.3.1:
Daim iav thib ob ntawm lub system yog cov hyperboloid. Nws cov congic coefficient yog -3. 838. Daim iav tseem ceeb yog qhov ua kom zoo tshaj plaws ntawm zernike txheem sag. Tus nqi ntawm thawj 14 yam khoom tau qhia hauv Table.3.2:
Qhov peb txoj cai qauv ntawm Golay4 lub tsom iav tsom iav tau qhia hauv Fig.3.1:
Fig.3.1 Peb txoj kev coj ua ntawm Golay3 Lub Cev Xov Tooj
Rau lub tshuab tsom iav pom kev ua haujlwm, qhov kev hloov kho kho qhov muag thiab cov ntaub duab yog feem ntau yog siv los ntsuas nws cov lus pom zoo. Fig.3.2 yog qhov chaw ntawm lub kaw lus ntawm lub system. Lub hauv paus siab tshaj plaws txhais tau tias square convent ntawm cov duab duab yog 3.514μm. Airy disk yog 3.308μm. Qhov kev xav zoo ntawm lub system yog qhov zoo.

4. Xaus
Kab lus no ua ntej qhia cov ntsiab lus ntawm kev sib sau ua ke thiab txoj kev ntawm kev ntsuas nws cov kev xav tau zoo. Tom qab ntawd siv zemax software los tsim cov golay3 sparse aperture ntau ntau daim iav tsom iav. Daim iav tseem ceeb uas tsim nrog kev sib ncaws aperture adopts ib qho dawb advedfe. Lub kaw lus tuaj yeem ua tiav tag nrho cov chaw ntawm ± 0. 16 degree}. 16 degree thiab ib qho kev sib sau ntawm ze li 51.92%. Nws yog qhov tseem ceeb rau kev txhim kho cov apertite loj astronomical.
