Vanhu vazhinji havagone kusiyanisa pakati pemutongi wegiya uye mutongi wegineti mumuchina wekuyeresa wechiratidzo.Nhasi tichataura pamusoro pekusiyana pakati pavo.
Iyo grating scale inzwa yakagadzirwa nemusimboti wekupindira kwechiedza uye diffraction.Kana magirati maviri ane pitch imwechete akaturikidzana, uye mitsetse inogadzira kona diki panguva imwe chete, zvino pasi pekuvhenekerwa kwechiedza chakafanana, symmetrically kupatsanurwa kwechiedza uye mitsetse yakasviba inogona kuoneka munzira yakatwasuka yemitsara.Inonzi Moiré fringes, saka Moiré fringes ndiwo maitiro akasanganiswa ekusiyanisa uye kukanganisa kwechiedza.Kana giraidhi richifambiswa nekanzwi kadiki, mipendero yemoiré inofambiswawo nemupendero mumwe chete.Nenzira iyi, tinogona kuyera hupamhi hwema moiré fringes zviri nyore kupfuura hupamhi hwemitsara yegrating.Mukuwedzera, sezvo imwe neimwe moire fringe inoumbwa nemharadzano yemitsara yakawanda ye grating, kana imwe yemitsara ine chikanganiso (kusaenzana kwepakati kana kutsetseka), iyi mutsara wakanganisa uye imwe mutsara wekugezera Nzvimbo yemharadzano yemitsara ichachinja. .Nekudaro, mupendero we moiré unoumbwa nemharadzano yakawanda yemitsara.Nokudaro, kuchinja kwechinzvimbo chemharadzano yemutsara kune zvishoma zvishoma pane imwe moiré fringe, saka iyo moire fringe inogona kushandiswa kuwedzera uye kuenzanisa.
Iyo magnetic scale inzwa inogadzirwa nekushandisa nheyo yemagineti matanda.Chigadziko chayo mutongi iuniformly magnetized steel strip.Mapango ayo S neN akaenzana pamutsara wesimbi, uye musoro wekuverenga unoverenga shanduko dzeS uye N matanda kuverenga.
Iyo grating chiyero inokanganiswa zvakanyanya netembiricha, uye nharaunda yekushandisa yakawanda iri pasi pe40 degrees Celsius.
Vhura magineti zviyero zviri nyore kukanganiswa nemagineti minda, asi yakavharwa magineti zviyero hazvina dambudziko iri, asi mutengo wakakwira.
