Dhinacyada wax soo saarka saxda ah iyo cilmi baarista sayniska, flatness ee dhufto ee saxda ah granite waa tilmaame muhiim ah si loo hubiyo saxnaanta qalabka. Kuwa soo socdaa waa horudhac tafatiran oo ku saabsan dhowr hab oo lagu ogaanayo guud ahaan iyo habraacyadooda hawleed ee adiga. ?
I. Habka ogaanshaha interferometer laser
Interferometer-ka laysarka ayaa ah aaladda la doorbido ee lagu ogaanayo flatness-ka saxda ah. Tusaale ahaan u soo qaado interferometer-ka laser-ka ee ZYGO GPI XP, xalintiisu waxa ay gaadhi kartaa 0.1nm. Markaad samaynayso ogaanshaha, marka hore isku hagaaji isha iftiinka interferometerka iyo madal oo u qaybi dusha sare ee meelaha 50mm × 50mm. Ka dib, xogta faragelinta faragelinta ayaa la soo ururiyay dhibco, xogtana waa la rakibay oo la falanqeeyay iyada oo la adeegsanayo polynomial Zernike si loo helo qaladka flatness. Habkani waa mid lagu dabaqi karo aaladaha saxda ah ee saxda ah waxaana lagu ogaan karaa khaladaadka flatness ≤0.5μm/m². Waxaa caadi ahaan loo adeegsadaa ogaanshaha mashiinnada sawir-qaadista iyo aaladaha cabbiraadda saddex-dhamaadka sare ee isku-duwayaasha. ?
Ii. Habka Array Heerka Elektaroonigga ah
Ogaanshaha qaabka elektiroonigga ah waa mid fudud in la shaqeeyo oo aad u hufan. Heerka elektiroonigga ah ee TESA A2 (oo leh xallinta 0.01μm/m) ayaa la doortay oo lagu habeeyey 9 × 9 array oo ay weheliyaan jihada dhidibka X/Y ee goobta. Iyadoo si isku mid ah loo ururiyo xogta u janjeerta heer kasta ka dibna la isticmaalo habka ugu yar ee labajibbaaran ee xisaabinta, qiimaha flatness si sax ah ayaa loo heli karaa. Habkani wuxuu si wax ku ool ah u aqoonsan karaa miyir-beelka maxalliga ah iyo xaaladaha isku-laabashada ee goobta. Tusaale ahaan, isbedbedelka 0.2μm ee dhexroorka 50mm ah ayaa sidoo kale la ogaan karaa, kaas oo ku habboon in si degdeg ah loo ogaado wax soo saarka ballaaran. ?
Iii. Habka crystal Flat Optical
Habka kristanta siman ee indhaha ayaa ku habboon in la ogaado meelaha yaryar ee meelaha yaryar. Ku dheji kristanta fidsan indhaha si adag oogada si loogu tijaabiyo goobta oo u fiirso faragelinta ka dhex sameysan iyaga oo iftiiminaya il monochromatic ah (sida nalka sodium). Haddii xariijimo toosan yihiin oo barbar socda, waxay tusinaysaa fidnaan wanaagsan. Haddi ay xariijimo qaloocan ay muuqdaan, xisaabi khaladka fidsanaanta oo ku salaysan heerka qalooca xariijimaha. Xariijimo kasta oo qaloocan waxay ka dhigan tahay farqiga dhererka 0.316μm, xogta fidsanaantana waxaa lagu heli karaa beddelaad fudud. ?
Afar. Habka kormeerka mashiinka cabbiraadda saddex-isku-duwan
Mashiinka cabbiraadda saddex-isku-duwan wuxuu gaari karaa cabbiraad sax ah oo sare oo bannaan oo saddex-cabbir ah. Dhig goobta granite miiska shaqada ee mishiinka cabbirada oo isticmaal baaraha si aad si isku mid ah uga soo ururiso xogta dhibcaha cabbirka badan ee dusha sare ee goobta. Nidaamka mashiinka cabbiraadda ayaa socodsiiya oo falanqeynaya xogtan si uu u soo saaro warbixinta flatness ee goobta. Habkani ma aha oo kaliya in la ogaado flatness, laakiin sidoo kale heli xuduudaha kale joomatari ee madal isku mar, oo ku haboon ogaanshaha dhamaystiran ee dhufto ee granite waaweyn. ?
Qabashada hababkan ogaanshaha waxay kaa caawin kartaa inaad si sax ah u qiimeyso flatness ee madal sax ah granite iyo bixinta dammaanad lagu kalsoonaan karo ee hawlgalka xasilloon ee qalabka saxda ah.
